Abstract
Enzymic dehydration of triose-phosphoric acid was a step in those carbohydrate metabolic reactions such as fermentation, glycolysis, and respiration. These were mediated in many cells by hexose phosphate. Cozy-mase was reduced to dihydro-cozymase by triosephosphoric acid in presence of triosephosphoric acid-apodehydrase. This reaction reached an equilibrium. Enzyme preps. from brain and yeast were used. Equilibrium between cozymase and dihydro-cozymase in the triosephosphate dehydrating system depended upon cozymase conc. and pH. Glycerin phosphoric acid was without effect on the equilibrium. Iodacetic acid in low, and phosphates in high concs. inhibited dehydration by triosephosphoric acid.This publication has 0 references indexed in Scilit:
