L-Deuterio-glutamic acid was isolated in pure form from algae grown in nutrient solution containing better than 99 per cent Dz0. The pH profile for the transamination of glutamic acid with pyridoxal shows a peak at pH 4. The presence of acetate buffer increases the reaction rate up to about seven ti
## Abstract Reaction rates for the protodesilylation of trimethylphenylsilane and of [2,4,6β^2^H~3~]βtrimethylphenylsilane by HCIO~4~, were measured in aqueous methanol (2:5, __v/v__) and the secondary deuterium isotope effect for the reaction was found to be __k__~H~/__k__~D3~ = 0.79. The magnitud
