# List of omics topics in biology

Inspired by the terms genome and genomics, other words to describe complete biological datasets, mostly sets of biomolecules originating from one organism, have been coined with the suffix -ome and -omics. Some of these terms are related to each other in a hierarchical fashion. For example, the genome contains the ORFeome, which gives rise to the transcriptome, which is translated to the proteome. Other terms are overlapping and refer to the structure and/or function of a subset of proteins (e.g. glycome, kinome).
An omicist is a scientist who studies omeomics, cataloging all the “omics” subfields.
Omics.org is a Wiki that collects and alphabetically lists all the known "omes" and "omics."

| Envirome | Enviromics | Gene related environment factors (envirome) | | |
| Environmental DNA | Environmental omics | Sequencing of ambient DNA | | |
| Epigenome | Epigenomics | Epigenetic modifications | Molecular genetics | Epigenomics is the study of the complete set of epigenetic modifications on the genetic material of a cell, collectively known as the epigenome |
| Exposome (2005) | Exposomics | An individual's environmental exposures, including in the prenatal environment | Molecular genetics | A proposed term and field of study of the disease-causing effects of environmental factors (the "nurture" component of "nature vs. nurture"). |
| Exposome (2009) | | Composite occupational exposures and occupational health problems | Occupational safety and health | The proposers of this term were aware of the previous term as used above but proposed to apply the term to a new field. |
| Exome | Exomics | Exons in a genome | Molecular Genetics | |
| Foodome | Foodomics | Food and Nutrition issues related to bioactivity, quality, safety and traceability of foods through the application and integration of advanced omics technologies to improve consumer's well-being, health, and confidence. | Nutrition | The term was first defined in 2009 |
| Genome | Genomics (Classical genetics) | Genes (DNA sequences/Chromosomes) | Genetics | "Genome" refers to the set of all genes in an organism. However, "genome" was coined decades before it was discovered that most DNA is "non-coding" and not part of a gene; thus, "genome" originally referred to the entire collection of DNA within an organism. Today, both definitions are used, depending on the context. |
| Glycome | Glycomics | Glycans | Glycobiology | |
| Hologenome | Hologenomics | Genomes of community members (i.e., holobionts) | Metagenomics | |
| Humeome | Humeomics | The chemical components of soil humus | Soil science | |
| Interferome | Interferomics | Interferons | Immunology | Also a database of the same name. |
| Interactome | Interactomics | All interactions | | The term "interactomics" is generally not used. Instead, interactomes are considered the study of systems biology. |
| Ionome | Ionomics | Inorganic biomolecules | Molecular Biology | |
| Kinome | Kinomics | Kinases | Molecular Biology | Proteins that add a phosphate group |
| Lipidome | Lipidomics | Lipids | Biochemistry | |
| Mechanome | Mechanomics | The mechanical systems within an organism | | |
| Metabolome | Metabolomics | Metabolites | | All products of a biological reaction (including intermediates) |
| Metagenome | Metagenomics | Genetic material found in an environmental sample | Molecular Biology | The genetic material is assumed to contain DNA from multiple organisms and therefore multiple genomes, hence the inclusion of the prefix meta-. |
| Metallome | Metallomics | Metals and metalloids | | |
| Microbiome | microbiomics | Collection of microorganisms in another organism such as an animal | Microbiology | |
| Obesidome | Obesidomics | Obesity related proteins | Proteomics | Coined by Pardo et al., 2012. |

| Parvome | Parvomics | Secondary metabolites | Biochemistry | Coined by Mark Martin and introduced by Julian Davies in 2008, referring to the Latin parvus for "small", and describing the "humungous microbial world of small (secreted) molecules of great structural diversity". See also |
