Flux, or metabolic flux is the rate of turnover of molecules through a metabolic pathway.
 Flux is regulated by the enzymes involved in a pathway.
 Within cells, regulation of flux is vital for all metabolic pathways to regulate the pathway's activity under different conditions.
 Flux is therefore of great interest in metabolic network modelling, where it is analysed via flux balance analysis.
Metabolomic Pathway Analysis, shortened to MetPA, is a freely available, user-friendly web server to assist with the identification analysis and visualization of metabolic pathways using metabolomic data.
 MetPA makes use of advances originally developed for pathway analysis in microarray experiments and applies those principles and concepts to the analysis of metabolic pathways.
 For input, MetPA expects either a list of compound names (identified as statistically significant or significant perturbed) or a metabolite concentration table with phenotypic labels (i.e. sick vs. healthy).
 The list of compounds can include common names, HMDB IDs or KEGG IDs with one compound per row.
 Compound concentration tables must have samples in rows and compounds in columns.
 MetPA’s output is a series of tables indicating which pathways are significantly enriched (along with accompanying statistics) as well as a variety of graphs or pathway maps illustrating where and how certain pathways were enriched.
 MetPA’s graphical output uses a colorful Google-Maps visualization system that allows simple, intuitive data exploration that lets users employ a computer mouse or track pad to select, drag and place images and to seamlessly zoom in and out.
 Users can explore MetPA’s output using three different views or levels: 1) a metabolome view; 2) a pathway view; 3) a compound view.
Zieve's syndrome is an acute metabolic condition that can occur during withdrawal from prolonged alcohol abuse.
 It is defined by hemolytic anemia (with spur cells and acanthocytes), hyperlipoproteinaemia (excessive blood lipoprotein), jaundice (elevation of unconjugated bilirubin), and abdominal pain.
 The underlying cause is liver delipidization.
 This is distinct from alcoholic hepatitis which, however, may present simultaneously or develop later.
Metabolic alkalosis is a metabolic condition in which the pH of tissue is elevated beyond the normal range (7.35-7.45).
 This is the result of decreased hydrogen ion concentration, leading to increased bicarbonate, or alternatively a direct result of increased bicarbonate concentrations.
The pentose phosphate pathway (also called the phosphogluconate pathway and the hexose monophosphate shunt) is a metabolic pathway parallel to glycolysis.
 It generates NADPH and pentoses (5-carbon sugars) as well as ribose 5-phosphate, the last one a precursor for the synthesis of nucleotides.
 While it does involve oxidation of glucose, its primary role is anabolic rather than catabolic.
The RecF pathway, also called the RecFOR pathway, is a pathway of homologous recombination that repairs DNA in bacteria.
 It repairs breaks that occur on only one of DNA's two strands, known as single-strand gaps.
 The RecF pathway can also repair double-strand breaks in DNA when the RecBCD pathway, another pathway of homologous recombination in bacteria, is inactivated by mutations.
 Like the RecBCD pathway, the RecF pathway requires RecA for strand invasion.
 The two pathways are also similar in their phases of branch migration, in which the Holliday junction slides in one direction, and resolution, in which the Holliday junctions are cleaved apart by enzymes.
Bilirubin (formerly referred to as haematoidin and discovered by Rudolf Virchow in 1847) is a yellow compound that occurs in the normal catabolic pathway that breaks down heme in vertebrates.
 This catabolism is a necessary process in the body's clearance of waste products that arise from the destruction of aged red blood cells. First the hemoglobin gets stripped of the heme molecule which thereafter passes through various processes of porphyrin catabolism, depending on the part of the body in which the breakdown occurs.
 For example, the molecules excreted in the urine differ from those in the faeces.
 The production of biliverdin from heme is the first major step in the catabolic pathway, after which the enzyme biliverdin reductase performs the second step, producing bilirubin from biliverdin.
The mevalonate pathway, also known as the isoprenoid pathway or HMG-CoA reductase pathway is an essential metabolic pathway present in eukaryotes, archaea, and some bacteria.
 The pathway produces two five-carbon building blocks called isopentenyl pyrophosphate (IPP) and dimethylallyl pyrophosphate (DMAPP), which are used to make isoprenoids, a diverse class of over 30,000 biomolecules such as cholesterol, heme, vitamin K, coenzyme Q10, and all steroid hormones.
Omega oxidation (ω-oxidation) is a process of fatty acid metabolism in some species of animals.
 It is an alternative pathway to beta oxidation that, instead of involving the β carbon, involves the oxidation of the ω carbon (the carbon most distant from the carboxyl group of the fatty acid).
 The process is normally a minor catabolic pathway for medium-chain fatty acids (10-12 carbon atoms), but becomes more important when β oxidation is defective.
The Small Molecule Pathway Database (SMPDB) is a comprehensive, high-quality, freely accessible, online database containing more than 600 small molecule (i.e. metabolic) pathways found in humans.
 SMPDB is designed specifically to support pathway elucidation and pathway discovery in metabolomics, transcriptomics, proteomics and systems biology.
 It is able to do so, in part, by providing colorful, detailed, fully searchable, hyperlinked diagrams of five types of small molecule pathways: 1) general human metabolic pathways; 2) human metabolic disease pathways; 3) human metabolite signaling pathways; 4) drug-action pathways and 5) drug metabolism pathways.
 SMPDB pathways may be navigated, viewed and zoomed interactively using a Google Maps-like interface.
 All SMPDB pathways include information on the relevant organs, subcellular compartments, protein cofactors, protein locations, metabolite locations, chemical structures and protein quaternary structures (Fig. 1).
 Each small molecule in SMPDB is hyperlinked to detailed descriptions contained in the HMDB or DrugBank and each protein or enzyme complex is hyperlinked to UniProt.
 Additionally, all SMPDB pathways are accompanied with detailed descriptions and references, providing an overview of the pathway, condition or processes depicted in each diagram.
 Users can browse the SMPDB (Fig. 2) or search its contents by text searching (Fig. 3), sequence searching, or chemical structure searching.
 More powerful queries are also possible including searching with lists of gene or protein names, drug names, metabolite names, GenBank IDs, Swiss-Prot IDs, Agilent or Affymetrix microarray IDs.
 These queries will produce lists of matching pathways and highlight the matching molecules on each of the pathway diagrams.
 Gene, metabolite and protein concentration data can also be visualized through SMPDB's mapping interface.
