| 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) |
| muramic acids | Compounds consisting of glucosamine and lactate joined by an ether linkage. They occur naturally as n-acetyl derivatives in peptidoglycan, the characteristic polysaccharide composing bacterial cell walls. (12 Dec 1998) |
| polyamino acids | Polypeptides that are polymers of aminoacyl groups, i.e., of -NH-CHR-CO-; typically, a term used with homopolymers. See: poly-. (05 Mar 2000) |
| polyenic acids | Fatty acids with more than one double bonds in the carbon chain; e.g., linoleic, linolenic, and arachidonic acids. Synonym: polyenic acids. (05 Mar 2000) |
| polyenoic acids | Fatty acids with more than one double bonds in the carbon chain; e.g., linoleic, linolenic, and arachidonic acids. Synonym: polyenic acids. (05 Mar 2000) |
| mycolic acids | Long-chain cyclopropanecarboxylic acids (C19-C21), further substituted by long-chain (C24-C30) alkanes containing free hydroxyl groups, found in certain bacteria; these waxy substances appear to be responsible for the acid-fastness of the bacteria that contain them. Synonym: mykol. (05 Mar 2000) |
| polymethacrylic acids | Poly-2-methylpropenoic acids. Used in the manufacture of methacrylate resins and plastics in the form of pellets and granules, as absorbent for biological materials and as filters; also as biological membranes and as hydrogens. Synonym: methylacrylate polymer; poly(methylacrylate); acrylic acid methyl ester polymer. (12 Dec 1998) |
| coumaric acids | Hydroxycinnamic acid and its derivatives. Act as activators of the indoleacetic acid oxidizing system, thereby producing a decrease in the endogenous level of bound indoleacetic acid in plants. (12 Dec 1998) |
| myristic acids | 14-carbon saturated monocarboxylic acids. (12 Dec 1998) |
| crotonic acids | 2-butenoic acids. 4-carbon monounsaturated monocarboxylic acids with the unsaturation in the 2 position. (12 Dec 1998) |
| propionic acids | 3-carbon saturated monocarboxylic acids. (12 Dec 1998) |
| heptanoic acids | 7-carbon saturated monocarboxylic acids. (12 Dec 1998) |
| prostanoic acids | 2-octylcyclopentaneheptanoic acids. The family of saturated carbon-20 cyclic fatty acids that represent the parent compounds of the prostaglandins. (12 Dec 1998) |
| hexuronic acids | Term used to designate tetrahydroxy aldehydic acids obtained by oxidation of hexose sugars, i.e. Glucuronic acid, galacturonic acid, etc. Historically, the name hexuronic acid was originally given to ascorbic acid. (12 Dec 1998) |
