| acids, noncarboxylic | Inorganic acids with a non metal, other than carbon, attached to hydrogen, or an acid radical containing no carbon. (12 Dec 1998) |
|---|---|
| acroleic acids | A series of unsaturated aliphatic acids of the general formula R==CH-COOH; the prototype, acrylic acid (R=CH2) or 2-propenoic acid, is derived from propionic acid by reduction or from glycerol by dehydration. Synonym: acroleic acids. (05 Mar 2000) |
| acrylic acids | A series of unsaturated aliphatic acids of the general formula R==CH-COOH; the prototype, acrylic acid (R=CH2) or 2-propenoic acid, is derived from propionic acid by reduction or from glycerol by dehydration. Synonym: acroleic acids. (05 Mar 2000) |
| adipic acids | A group of dicarboxylic acids that are structurally related to hexanedioic acid (adipic acid). (12 Dec 1998) |
| aldonic acids | Monosaccharide derivatives in which the aldehyde group has been oxidised to a carboxyl group. They may form lactones (e.g., galactonic acid). Synonym: glyconic acids. (05 Mar 2000) |
| aliphatic acids | The acids of nonaromatic hydrocarbons (e.g., acetic, propionic, butyric acids); the so-called fatty acids of the formula R-COOH, where R is a nonaromatic (aliphatic) hydrocarbon. (05 Mar 2000) |
| alkanesulfonic acids | Sulfonic acid derivatives that are substituted with an aliphatic hydrocarbon group. (12 Dec 1998) |
| amino acids | Organic compounds that generally contain an amino (-nh2) and a carboxyl (-cooh) group. Twenty alpha-amino acids are the subunits which are polymerised to form proteins. (12 Dec 1998) |
| amino acids, branched-chain | Amino acids which have a branched carbon chain. (12 Dec 1998) |
| amino acids, cyclic | A class of amino acids characterised by a closed ring structure. (12 Dec 1998) |
| amino acids, peptides, and proteins | Amino acids and chains of amino acids connected by peptide linkages. (12 Dec 1998) |
| aminobutyric acids | <chemistry> Aliphatic four carbon acids substituted in any position(s) with amino group(s). They are found in most living things. The best known is gaba. (12 Dec 1998) |
| aminohippuric acids | A group of glycine amides of aminobenzoic acids. (12 Dec 1998) |
| aminoisobutyric acids | A group of compounds that are derivatives of the amino acid 2-amino-2-methylpropanoic acid. (12 Dec 1998) |
| aminosalicylic acids | Amino-2-hydroxybenzoic acids. A group of hydroxybenzoic acids that include substitution by amino groups at the 3-, 4-, 5-, or 6-position. The 4-amino derivative, p-aminosalicylic acid, is an antitubercular agent. (12 Dec 1998) |
