bromochloroacetic acid Keratins: A class of fibrous proteins or scleroproteins that represents the principal constituent of EPIDERMIS; HAIR; NAILS; horny tissues, and the organic matrix of tooth ENAMEL. Two major conformational groups have been characterized, alpha-keratin, whose peptide backbone forms a coiled-coil alpha helical structure consisting of TYPE I KERATIN and a TYPE II KERATIN, and beta-keratin, whose backbone forms a zigzag or pleated sheet structure. alpha-Keratins have been classified into at least 20 subtypes. In addition multiple isoforms of subtypes have been found which may be due to GENE DUPLICATION.. bromochloroacetic acid : A monocarboxylic acid that is acetic acid in which one of the methyl hydrogens is replaced by bromine while a second is replaced by chlorine. A low-melting (27.5-31.5degreeC), hygroscopic crystalline solid, it can be formed during the disinfection (by chlorination) of water that contains bromide ions and organic matter, so can occur in drinking water as a byproduct of the disinfection process. | 1.96 | 1 | 0 | 2-bromocarboxylic acid; monocarboxylic acid; organochlorine compound | |

aldrin Aldrin: A highly poisonous substance that was formerly used as an insecticide. The manufacture and use has been discontinued in the U.S. (From Merck Index, 11th ed). aldrin : An organochlorine compound resulting from the Diels-Alder reaction of hexachlorocyclopentadiene with norbornadiene. A proinsecticide (by epoxidation of the non-chlorinated double bond to give dieldrin), it was widely used as an insecticide before being banned in the 1970s as a persistent organic pollutant. | 2.02 | 1 | 0 | | |
