| hydroxamic acids | A class of weak acids with the general formula r-conhoh. (12 Dec 1998) |
|---|---|
| hydroxy acids | Organic compounds containing both the hydroxyl and carboxyl radicals. (12 Dec 1998) |
| hydroxybenzoic acids | Benzoic acid substituted by one or more hydroxy groups in any position on the benzene ring. (12 Dec 1998) |
| hydroxyeicosatetraenoic acids | Eicosatetraenoic acids substituted in any position by one or more hydroxy groups. They are important intermediates in a series of biosynthetic processes leading from arachidonic acid to a number of biologically active compounds such as prostaglandins, thromboxanes, and leukotrienes. (12 Dec 1998) |
| sialic acids | A group of naturally occurring n-and o-acyl derivatives of the deoxyamino sugar neuraminic acid. They are ubiquitously distributed in many tissues. (12 Dec 1998) |
| naphthaleneacetic acids | Naphthalene derivatives containing the -ch2cco2h radical at the 1-position, the 2-position, or both. Compounds are used as plant growth regulators to delay sprouting, exert weed control, thin fruit, etc. (12 Dec 1998) |
| stearic acids | A group of compounds that are derivatives of octadecanoic acid which is one of the most abundant fatty acids found in animal lipids. (12 Dec 1998) |
| nicotinic acids | 2-, 3-, or 4-pyridinecarboxylic acids. Pyridine derivatives substituted with a carboxy group at the 2-, 3-, or 4-position. The 3-carboxy derivative (niacin) is active as a vitamin. (12 Dec 1998) |
| sugar acids | Acids, such as gluconic, glycuronic, and saccharic acid, produced by the oxidation of glucose. (05 Mar 2000) |
| sulfanilic acids | Aminobenzenesulfonic acids. Organic acids that are used in the manufacture of dyes and organic chemicals and as reagents. (12 Dec 1998) |
| nucleic acids | Highly complex portions of nucleoproteins that yield a mixture of purines and pyrimidines, a ribose or deoxyribose component, and phosphoric acid on complete hydrolysis. The two general types are ribonucleic acid (RNA) and deoxyribonucleic acid (DNA). (12 Dec 1998) |
| nucleic acids, nucleotides, and nucleosides | Complex compounds of high molecular weight occurring in living cells. These are basically of two types, ribonucleic (RNA) and deoxyribonucleic (DNA) acids, both of which consist of nucleotides (nucleoside phosphates linked together by phosphate bridges). (12 Dec 1998) |
| sulfenic acids | Oxy acids of sulfur with the general formula rsoh, where r is an alkyl or aryl group such as ch3. They are often encountered as esters and halides. (12 Dec 1998) |
| sulfinic acids | Any of the monobasic inorganic or organic acids of sulfur with the general formula rso(oh). (12 Dec 1998) |
| sulfonic acids | Inorganic or organic oxy acids of sulfur which contain the rso2(oh) radical. (12 Dec 1998) |
