| halogen | <chemistry> An electronegative element or radical, which, by combination with a metal, forms a haloid salt; especially, chlorine, bromine, and iodine; sometimes, also, fluorine and cyanogen. See Chlorine family, under Chlorine. Origin: Gr. "als, "alos, salt + -gen: cf. F. Halogene. Source: Websters Dictionary (01 Mar 1998) |

| transferases (other substituted phosphate groups) | <enzyme> A class of enzymes that transfers substituted phosphate groups. Registry number: EC 2.7.8 (12 Dec 1998) |
| aliphatic | <biochemistry, chemistry> A major class of organic compounds where carbon and hydrogen molecules are arranged in straight or branched chains. A type of hydrocarbon that includes alkanes, alkenes, and alkynes. (13 Nov 1997) |
| 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) |

| polycyclic hydrocarbons, aromatic | <chemical> A major group of unsaturated cyclic hydrocarbons containing two or more rings. The vast number of compounds of this important group, derived chiefly from petroleum and coal tar, are rather highly reactive and chemically versatile. The name is due to the strong and not unpleasant odour characteristic of most substances of this nature. Pharmacological action: carcinogens. (12 Dec 1998) |
