|---|---|
| acyclic acid | <chemistry> Carboxylic acids that have open-chain molecular structures as opposed to ring-shaped structures. (25 Jun 1999) |
| acyclic compound | An organic compound in which the chain does not form a ring. Synonym: aliphatic compound, open chain compound. (05 Mar 2000) |
| acyclic monoterpene primary alcohol - NADP oxidoreductase | <enzyme> From catmint nepeta racemosa; involved in the biosynthesis of iridoid monoterpenes; oxidises geraniol, nerol, and their 10-hydroxy derivatives in the presence of nadp(+). Registry number: EC 1.1.1.- Synonym: monoterpene primary alcohol - nadp oxidoreductase, ampano (26 Jun 1999) |
| hydrocarbons, acyclic | Organic compounds composed exclusively of carbon and hydrogen where no carbon atoms join to form a ring structure. (12 Dec 1998) |
| acids, carbocyclic | Carboxylic acids that have a homocyclic ring structure in which all the ring atoms are carbon. (12 Dec 1998) |
| acids, heterocyclic | A class of acids containing a ring structure in which atleast one atom other than carbon is incorporated. (12 Dec 1998) |
| 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) |
