Glycerol
A trihydroxy sugar alcohol that is an intermediate in carbohydrate and lipid metabolism. It is used as a solvent, emollient, pharmaceutical agent, or sweetening agent.
Year introduced: 1998
Solvents
Liquids that dissolve other substances (solutes), generally solids, without any change in chemical composition, as, water containing sugar. (Grant and Hackh's Chemical Dictionary, 5th ed)
Cryoprotective Agents
Substances that provide protection against the harmful effects of freezing temperatures.
Year introduced: 1972(1967)
Sugar Alcohols
Polyhydric alcohols having no more than one hydroxy group attached to each carbon atom. They are formed by the reduction of the carbonyl group of a sugar to a hydroxyl group. (From Dorland, 28th ed)
Year introduced: 1972
Organic Chemicals
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.
Carbohydrates
A class of organic compounds composed of carbon, hydrogen, and oxygen in a ratio of Cn(H2O)n. The largest class of organic compounds, including STARCH; GLYCOGEN; CELLULOSE; POLYSACCHARIDES; and simple MONOSACCHARIDES.
Year introduced: /metabolism was CARBOHYDRATE METABOLISM 1963-1965
Alcohols
Alkyl compounds containing a hydroxyl group. They are classified according to relation of the carbon atom: primary alcohols, R-CH2OH; secondary alcohols, R2-CHOH; tertiary alcohols, R3-COH. (From Grant and Hackh's Chemical Dictionary, 5th ed)
Triose Sugar Alcohols
Sugar alcohol molecules that contain three carbons.
Year introduced: 2018
Physiological Effects of Drugs
Activities which affect organs and systemic functions without regard to a particular disease.
Year introduced: 2004
Specialty Uses of Chemicals
Uses of chemicals in a research, industrial, or household setting. This does not include PHARMACOLOGIC ACTIONS.
Year introduced: 2004(1999)
Pharmacologic Actions
A broad category of chemical actions and uses that result in the prevention, treatment, cure or diagnosis of disease. Included here are drugs and chemicals that act by altering normal body functions, such as the REPRODUCTIVE CONTROL AGENTS and ANESTHETICS. Effects of chemicals on the environment are also included.
Chemical Actions and Uses
A group of pharmacologic activities, effects on living systems and the environment, and modes of employment of drugs and chemicals. They are broken into actions, which describe their effects, and uses, which describe how they are employed.
Year introduced: 1999
Protective Agents
Synthetic or natural substances which are given to prevent a disease or disorder or are used in the process of treating a disease or injury due to a poisonous agent.
