| choleic acids | Compounds of bile acids and sterols. (05 Mar 2000) |
|---|---|
| cholic acids | <chemical> The 3 alpha,7 alpha,12 alpha-trihydroxy-5 beta-cholanic acid family of bile acids in man, usually conjugated with glycine or taurine. They act as detergents to solubilise fats for intestinal absorption, are reabsorbed by the small intestine, and are used as cholagogues and choleretics. Pharmacological action: cholagogues and choleretics, gastrointestinal agents. (12 Dec 1998) |
| chrysanthemum-carboxylic acids | Cyclopropane carboxylic acids substituted in one position by two methyl groups, the other by 2-methyl-1-propenyl (chrysanthemum monocarboxylic acid) or by 3-methoxy-2-methyl-3-oxo-1-propenyl (chrysanthemum dicarboxylic acid methyl ester); these acids, esterified with allethrolone or pyrethrolone, are the allethrins and pyrethrins, respectively. (05 Mar 2000) |
| phenylpyruvic acids | A group of compounds that are derivatives of phenylpyruvic acid which has the general formula c6h5ch2cocooh, and is a metabolite of phenylalanine. (12 Dec 1998) |
| phosphatidic acids | Fatty acid derivatives of glycerophosphates. They are composed of glycerol bound in ester linkage with 1 mole of phosphoric acid at the terminal 3-hydroxyl group and with 2 moles of fatty acids at the other two hydroxyl groups. (12 Dec 1998) |
| phosphinic acids | Hypophosphorous acids. Inorganic or organic derivatives of phosphinic acid, h2po(oh). They include phosphinates and phosphinic acid esters. (12 Dec 1998) |
| phosphoamino acids | Amino acids that contain phosphorus as an integral part of the molecule. (12 Dec 1998) |
| phosphonic acids | Inorganic or organic derivatives of phosphonic acid with the general formula rop(oh)2. This includes phosphonates and phosphonic acid esters. The tautomeric form of this compound (p(oh)3) = phosphorous acids. (12 Dec 1998) |
| phosphoric acids | Inorganic derivatives of phosphoric acid (h3po4). Inorganic salts are known as phosphates and organic esters are phosphoric acid esters. (12 Dec 1998) |
| phosphorous acids | Inorganic or organic derivatives of phosphorous acid (p(oh)3). Inorganic salts are known as phosphites. The tautomeric form of this compound (hpo(oh)2) = phosphonic acids. (12 Dec 1998) |
| phosphorus acids | Inorganic acids that contain phosphorus as an integral part of the molecule. (12 Dec 1998) |
| clavulanic acids | <chemical> Acids, salts, and derivatives of clavulanic acid (c8h9o5n). They consist of those beta-lactam compounds that differ from penicillin in having the sulfur of the thiazolidine ring replaced by an oxygen. They have limited antibacterial action, but block bacterial beta-lactamase irreversibly, so that similar antibiotics are not broken down by the bacterial enzymes and therefore can exert their antibacterial effects. Pharmacological action: antibiotics, lactam, enzyme inhibitors. (12 Dec 1998) |
| phthalic acids | A group of compounds that has the general structure of a dicarboxylic acid-substituted benzene ring. The ortho-isomer is used in dye manufacture. (12 Dec 1998) |
| pimelic acids | A group of compounds that are derivatives of heptanedioic acid with the general formula r-c7h11o4. (12 Dec 1998) |
| monounsaturated fatty acids | A fatty acid chain with at least two empty spaces that could be hydrogenated (have a hydrogen atom added). Saturated (hydrogenated) fatty acids are a greater health risk for the development of atherosclerotic vascular disease. (27 Sep 1997) |
