| nucleic acid probes | Nucleic acid which complements a specific mRNA or DNA molecule, or fragment thereof; used for hybridization studies in order to identify microorganisms and for genetic studies. (12 Dec 1998) |
|---|---|
| nucleic acid renaturation | The reformation of all, or part of, the native conformation of a nucleic acid molecule after the molecule has undergone denaturation. (12 Dec 1998) |
| nucleic acid synthesis inhibitors | Compounds that inhibit cell production of DNA or RNA. (12 Dec 1998) |
| in situ nucleic acid hybridization | <molecular biology> The use of a DNA or RNA probe to detect the complementary DNA sequence. (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) |
| amino acids, branched-chain | Amino acids which have a branched carbon chain. (12 Dec 1998) |
