“This is caused by a dehydration reaction between the hydroxyl group from the glycerol and the carboxyl groups of the fatty acids.”

“Compounds in which two hydroxyl groups are attached to the same carbon atom normally cannot be isolated.”

“When this hydroxyl group is then methylated to give there is a very significant, 3000-fold, decrease in inhibitor binding.”

“Betacynin biosynthesis starts by the oxidation of tyrosine to dopa by a tyrosine hydroxylase.”

“For nicotinate hydroxylase assays, cnxE strains were first crossed to a mutant in the structural gene encoding xanthine dehydrogenase to generate cnxE hxA1 double mutants.”

“It is noteworthy that the values obtained for the wild type in cells grown in the presence of molybdate are lower for nitrate reductase and nicotinate hydroxylase.”

“This analysis indicated that, tentatively, increased stem elongation was accompanied by a promotion of cutin monomer hydroxylation.”

“Flavonoids are plant derivatives of flavone with various degrees of hydroxylation and glycosidic substitutions.”

“However, some children display slow hydroxylation and clear tricyclic antidepressants more slowly.”
