/chemistry .
/chemical characterization .
/chemical composition .
/chemical content .
/chemical properties .
/chemical structure .
Used with chemicals, biological, and non-biological substances for their composition, structure, characterization, and properties; also used for the chemical composition or content of organs, tissue, tumors, body fluids, organisms, and plants. Excludes chemical analysis and determination of substances for which "analysis" is used; excludes synthesis for which "chemical synthesis" is used; excludes isolation and purification of substances for which "isolation & purification" is used. .

Organic Chemicals .
Chemicals, Organic .
Organic Substances .
A broad class of substances containing carbon and its derivatives. Many of these chemicals will frequently contain hydrogen with or without oxygen, nitrogen, sulfur, phosphorus, and other elements. They exist in either carbon chain or carbon ring form. .

/chemical synthesis .
Used for the chemical preparation of molecules in vitro. For the formation of chemical substances in organisms, living cells, or subcellular fractions, "biosynthesis" is used. .

/pharmacologic action .
Used with drugs and exogenously administered chemical substances for their effects on living tissues and organisms. It includes acceleration and inhibition of physiological and biochemical processes and other pharmacologic mechanisms of action. .

Indicators .
Reagents and Indicators .
Reagents .
Substances used for the detection, identification, analysis, etc. of chemical, biological, or pathologic processes or conditions. Indicators are substances that change in physical appearance, e.g., color, at or approaching the endpoint of a chemical titration, e.g., on the passage between acidity and alkalinity. Reagents are substances used for the detection or determination of another substance by chemical or microscopical means, especially analysis. Types of reagents are precipitants, solvents, oxidizers, reducers, fluxes, and colorimetric reagents. (From Grant & Hackh's Chemical Dictionary, 5th ed, p301, p499) .

/metabolism .
/biochemical pathways .
/biodegradation .
/biotransformation .
/catabolism .
/degradation .
/incorporation .
/mobilization .
/turnover .
Used with organs, cells and subcellular fractions, organisms, and diseases for biochemical changes and metabolism. It is used also with drugs and chemicals for catabolic changes (breakdown of complex molecules into simpler ones). For anabolic processes (conversion of small molecules into large), BIOSYNTHESIS is used. For enzymology, pharmacokinetics, and secretion use the specific subheadings. .
