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. |
