Cambridge Isotope Laboratories, Inc.

Foodomics, a term coined in 2009 by Cifuentes,1 is a discipline that studies food and nutrition in relation to its impact on a consumer’shealth and disease. Applicable applications include, but are not limited by, the evaluation of food composition, safety, quality, additives,adulterants, and contaminants. Such studies integrate information from multiple research areas (spanning ‘omics and environmental).
A blend of analytical technologies has been utilized therein to obtain deeper insights into the impact/mechanisms that the compounds
in food /beverage samples have on biological systems.
Cambridge Isotope Laboratories, Inc. (CIL) is pleased to offer a multitude of highly characterized stable isotope-labeled and unlabeledstandards in their neat and/or solution form for food and beverage analysis. The following presents a sampling of our chemical standards
to aid foodomics research and testing. Please see isotope.com/products for a comprehensive list of our offerings and for additional
information on those presented below.

Metabolic Biomolecules

Cambridge Isotope Laboratories, Inc.
isotope.com

Metabolomics is conventionally used to study the small molecules (called metabolites) present in biological systems.
These metabolites are complex (due, for example, to diversity of physicochemical properties, structure, concentration)
and are categorized according to their chemical structures in what is referred to as metabolic class (e.g., amino acids,
fatty acids and lipids, vitamins). Metabolites are used as internal standards within metabolomic methods in foodscience to, for example, assess nutritional content, study dietary intake, screen for candidate or valid health/diseasebiomarkers, and gain insights into pathway mechanisms affecting human nutrition, among other purposes.
The following sections outline example biochemical standards spanning a number of metabolic classes pertaining
to the foodomics research and testing sector.

Amino Acids and Derivatives
Amino acids are building blocks of peptides and proteins. These starting materials serve as key intermediates
in various metabolic pathways (e.g., citric acid cycle, urea cycle) and are required for the proper functioning of
biological systems. The analysis of amino acids /proteins in food (e.g., eggs, fish, turkey) and feed (e.g., animal food)is conducted for a variety of reasons, spanning from nutritional assessment to process quality control (e.g., proteinhydrolysis, oxidative degradation). To complement method development and testing in this research space, CIL offersa plethora of stable isotope-labeled (and unlabeled) free amino acids with uniform or positional labeling patterns ofdifferent stereochemical orientations (i.e., D, L, and DL).

Caffeine and Its Metabolites
Caffeine is a psychoactive stimulant of the central nervous system that is extensively consumed worldwide. MS-based research into thekinetics/metabolism of this compound and its metabolites (e.g., paraxanthine, theobromine, theophylline) has revealed insight into its healthimpact and abuse in humans. Studies further suggest an influence on pharmacological activity and neurodegeneration; thus, strengthening
a need for its robust and accurate analysis in food and beverage products. To support such endeavors, CIL offers stable isotope-labeled
caffeine and a collection of its isotopically labeled metabolites as neat standards.

Carbohydrates
Carbohydrates are organic compounds that are structurally classified as polyhydroxy aldehydes or ketones. These are integral biomolecules
to the functional process of living systems (e.g., cell-to-cell signaling, immune responses, protein folding) and are contained in natural/
processed food and beverages in their simple or complex form. The identity and concentration of carbohydrates is an important aspectof food science for a number of reasons (e.g., nutritional labeling, quality control). To aid these and other research activities, CIL offers anumber of stable isotope-labeled carbohydrates spanning several of its subclasses (e.g., monosaccharides, disaccharides, polysaccharides,
sugar alcohols). These standards are available in various labeling patterns in their neat form.

Elements and Their Compounds
CIL offers an extensive inventory of stable isotope-labeled elements and their compounds. These materials are amenable for a wide
range of applications, encompassing ‘omics (foodomics included), agriculture, botany, and conductivity measurements, all enabledthrough element-specific detection methods. In foodomic science, the presence and concentration of elements (e.g., trace and heavy
metals) is important to, for example, determining exposure levels and their risk or benefit to human health. In application, the isotopelabeled elements or compounds could be used as matrix spike standards in the qualitative/quantitative analyses of food and feed
products, dietary supplements, beverages, and biosamples.

Fatty Acids and Lipids
Fatty acids and lipids are important biological compounds that are essential to the regulation and control of cellularfunctions and metabolic pathways. These are present in a variety of foods (e.g., animal fat, fish and vegetable oil,fruits, nuts/seeds) and are analyzed at qualitative/quantitative levels in foodomics research. To support these andother initiatives (e.g., structure and physicochemical property analysis), CIL is pleased to offer a multitude of stable
isotope-labeled (and unlabeled) fatty acids and lipids. The fatty acids cover saturated and unsaturated classes, while
the lipids include ceramides (e.g., N-palmitoyl-D-sphingosine, N-oleoyl-D-sphingosine) and triacylglycerides (e.g.,
tripalmitin, tristearin, triolein). These standards are available in various labeling patterns (i.e., uniform, partial) andforms (i.e., free acid, salt, ester).

Organic Acids and Their Conjugate Salts
Organic acids (OAs) play essential roles in energy metabolism pathways (e.g., glycolysis, tricarboxylic acid cycle), with the short-chained
OAs having emerged as important regulators of host immune response and transcriptional regulation. These biochemicals are present inmany foods naturally and are being utilized in industrial food and beverage production as preservatives, acidulants, and /or as flavorants.
To help facilitate their qualitative /quantitative analysis in metabolic and foodomic studies, CIL is pleased to offer a collection of stable
isotope-labeled (and unlabeled) OAs along with their conjugate salts in their free and/or mixture form. These standards encompass
monocarboxylic (e.g., acetic, lactic), dicarboxylic (e.g., malic, succinic), and tricarboxylic (e.g., cis-aconitic, citric) acids.

Vitamins and Their Metabolites
Vitamins are organic compounds that directly or indirectly participate in organisms’ biochemical reactions. These are
divided into two classes, based on their solubility in fat (includes A, D, E, and K) and water (includes B and C), andcan be obtained through a variety of sources (e.g., carrots and tuna for A, animal products for the Bs, citrus fruits forC, sunlight for D). CIL offers stable isotope-labeled (and unlabeled) vitamins as neat compounds and/or as solutionsat specified concentrations for food-science research. The standards help facilitate accurate/precise quantificationand food testing of vitamins in biological matrices and food-related products.

Food Contaminants

Standards for

In addition to the nutrients and natural components of food, we must also consider the effects of additives,contaminants, and adulterants in food. Testing for the presence of contaminants and metabolites has become
increasingly more routine and, in many cases, drives the implementation of new regulations and /or acceptable daily
intake levels. The following sections outline example products for a number of environmental-contaminant classes
pertaining to the foodomics research sector.

Bisphenols
Bisphenol A (BPA) is a synthetic compound that has long been used in the production of polycarbonate plastics
and epoxy resins, largely as a component in food and beverage containers. BPA can mimic estrogen in the body,potentially interfering with functionality of the endocrine system. BPA has been banned for use in certain products
related to food and beverage consumption, and manufacturers have turned to other bisphenol compounds asalternatives. CIL offers stable-isotope labeled and native bisphenol and bisphenol-related compounds, including
glucuronide conjugated standards, bissulfate conjugated standards, and bisphenol diglycidyl ethers.

Cannabinoids
Research suggests that the cannabis plant produces between 80-100 cannabinoids, with the main ones being tetrahydrocannabinol(THC) and cannabidiol (CBD). THC is the compound responsible for the psychoactive effects associated with cannabis use, whereas CBD is
associated with antipsychoactive effects. Human use of cannabinoids occurs via recreational, medicinal, and synthetic routes. CBD has been
gaining popularity for use in a variety of topical and ingestible wellness products, with the proposed benefits of providing relief from mild
pain or discomfort, stress, and occasional sleeplessness. CIL has developed stable isotope-labeled and native standards of THC, CBD, andother cannabinoids to assist researchers with their testing needs.

Chloropropanols
Chloropropanols have been of increased interest for detection in food, with a focus on oyster and soy sauces. It is thought thatthe compounds are formed during the production of hydrolyzed vegetable protein in the presence of hydrochloric acid. The majorchloropropanols that can be found in foods are 3-chloro-1,2-propanediol (3-MCPD) and 1,3-dichloro-2-propanol (1,3-DCP). 3-MCPD
has been shown to cause cancer in laboratory animals that consumed large amounts over their lifetimes,1 and although people generally
consume low amounts of these contaminants in food, there is still concern over the potential health risk.

Cyanotoxins
Cyanotoxins are toxic bioactive compounds that are released from planktonic cyanobacteria (blue-green algae) undercertain conditions. This can result in harmful algal blooms (HABs) that contaminate water systems and bioaccumulate
in aquatic vertebrates / invertebrates. Cyanotoxins are also potentially an issue for health and dietary foodsupplements derived from algae.

Dioxins/Furans
Dioxins and furans are a family of toxic substances that can be found as byproducts in commercial organochlorine
pesticide formulations, chlorine-bleached pulp and paper products, and incineration of organic material in thepresence of chlorine. The compounds can build up in the fatty tissues of animals, leading to the main source ofhuman exposure through ingestion of contaminated pork, beef, poultry, fish, and dairy products. CIL offers stableisotope labeled and native individual dioxin and furan standards, and has for many decades collaborated withregulators to develop standard mixtures used in US EPA, European, and Japanese standardized methods. CIL alsooffers mixtures containing dioxins, furans, and PCBs as well as standard mixtures for food /feed testing.

Flame Retardants
Flame retardants (FRs) have been used for decades in electronics, textiles, and other industrial products, and many
have demonstrated “POPs” characteristics for stability, toxicity, long-range transport, and bioaccumulation. FRs havelong been detected in the environment, and studies have shown their presence in food as well, often due to contact
with packaging and food handling equipment. CIL offers stable isotope-labeled and native brominated diphenyl
ether (BDE) standards and standard mixtures, BDE metabolites, US EPA Method 1614 and RoHS BDE standard
mixtures, alternative halogenated flame retardants, polybrominated biphenyls (PBB), phosphate flame retardants(PFR), and multiclass BFR calibration and spiking mixtures.

Melamine and Melamine Byproducts▼

Melamine and cyanuric acid have been identified as the source of two notable human- and pet-food poisonings.
Manufacturers sometimes illegally add melamine to food and beverage products to artificially boost protein values.
Melamine contains small amounts of cyanuric acid and, when hydrogen bonded with one another, highly insoluble
melamine cyanurate crystals form in the kidneys. These crystals have led to numerous cases of renal failure and evendeath to both humans and animals.

Nitrofuran Metabolites
Nitrofuran drugs have been used in veterinary applications as antimicrobial treatments, as well as prophylactic growth promoters. While
many of these compounds are now banned in food-producing species such as pigs, cattle, turkeys, chicken, goats, and sheep, the concern
remains for potential illegal use in these species. Several nitrofuran metabolites such as AHD, AOZ, AMOZ, and SEM remain important
markers to determine potential illegal use of nitrofuran drug use.

Nitrosamines
Nitrosamines are a group of organic compounds which may be found in processed foods and beverages, as well as
cosmetics and tobacco. Many of the compounds within this class are suspected carcinogens, with human exposure
mainly occurring from use of tobacco products and consumption of cured and processed foods. CIL provides a rangeof nitrosamine standards to assist researchers, offering both native and stable isotope-labeled internal standards for
accurate, low-level detection in various matrices.

Parabens▼

Parabens are a class of 4-hydroxybenzoate alkyl esters commonly used as preservatives in the cosmetic,
pharmaceutical, and food industries as antimicrobial agents. There is growing concern over the estrogen-likebehavior of parabens and their metabolites, causing many consumers and manufacturers to seek paraben-freealternatives. CIL offers stable isotope-labeled and native paraben and paraben metabolite standards, as well as
mixtures combined with other phenolic compounds.

Per- and Polyfluoroalkyl Substances (PFAS)▼

PFAS have been one of the most discussed classes of chemical pollutants in recent years, and many have been
scrutinized and even withdrawn from production over the past two decades. PFAS have been largely detectedin water samples near manufacturing sites, including drinking water sources. PFAS have also been used in foodpackaging materials as they are resistant to saturation by oil and steam, leading to contact food contamination.
CIL offers stable isotope-labeled and native standards for many of the traditional PFAS classes, as well as emerging
fluoropolymer classes. CIL also offers several native and labeled multicomponent standard mixtures, including US
EPA Method 537 and 537.1 mixtures.

Phthalates and Phthalate-Replacement Products▼

Phthalates are a class of industrial chemicals used to increase the flexibility, durability, transparency, and longevityof plastics. The main source of food contamination occurs through contact with packaging and food-handlingequipment. Phthalates have been associated with causing reproductive and endocrine-related health issues inhumans, and regulations for certain phthalates have been enacted. CIL offers stable isotope-labeled and native
phthalates and phthalate metabolites, as well as phthalate-related compounds. A mixture of phthalate andphthalate-replacement metabolites is also available.

Polychlorinated Biphenyls (PCBs)
PCBs are a class of synthetic chemicals that were widely used in electrical equipment, such as transformers and capacitors. PCBs werebanned from production in most countries in the 1970s, though large-scale contamination of the environment remains a problem today.
The compounds accumulate within the food chain, with the highest concentrations being in the fatty tissues of animals, dairy products, andfish. Ingestion of these contaminated food sources accounts for over 90% of human exposure to PCBs.1 CIL offers stable isotope-labeled
and native individual PCB standards, as well as US EPA Method 1668, CEN Method EN-1948-4, WHO “dioxin-like” and “non-dioxin-like”
mixtures, and combined dioxin, furan, and PCB mixtures.
