title: Inhibition of alpha-chymotrypsin by 2-halogeno-ethanols; comparisons with 2-methyl-ethanols and urea.
abstract: 2-Halogeno- and 2-methyl-ethanols inhibit alpha-chymotrypsin in the order of their substituted groups: [1] tri- greater than di- greater than mono-, [2] Br- greater than Cl- greater than CH3- greater than F-. The inhibition by the halogeno-ethanols is mediated differently from that by the methyl-ethanols, ethanol, and urea.
