| humic acids | <chemical> Allomelanins found in soils, coals, and peat, resulting from the decomposition of organic matter, particularly dead plants. They are a mixture of complex macromolecules having polymeric phenolic structures with the ability to chelate metals, especially iron. (merck index, 11th ed) Pharmacological action: chelating agents. Chemical name: Humic acids (12 Dec 1998) |

| 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) |
| succinic acids | A class of dicarboxylic acids with the general structure of butanedioic acid (succinic acid). They are used in perfumery and as a chemical intermediate in medicine. (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) |
| 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) |
