This category links to categories with sites in which the topic is analysis of chemicals from living things. Nowadays, many of these analytes can be synthesized with out the need for a biological source.
The term is also used in cases where the analyte may be inorganic but the matrix is biological, such as iron in blood.
For cases of the presence of biological or inorganic contaminants in water, or effluent, see Environmental_Chemistry.
Category to supplement the Proteins_and_Enzymes category, for synthetic peptides, specifically used in Biochemical and Molecular Biology research and diagnostics.
For suppliers and reagents used in synthesis, see Biochemistry_and_Molecular_Biology: Products_and_Services: Peptides.
Only submit your site here, if it describes an analytical laboratory offering both biological and chemical testing.
If the laboratory specializes in Food or Environmental samples, submit it instead to Food_Science: Products and Services or Science: Environment: Products and Services, respectively.
