Amino Acid Composition of Cereal and Oilseed

Abstract

Quantitative amino acid composition of acid hydrolysates was determined for samples of some Polish varieties of cereal grain (wheat, rye, barley, oats, millet and buckwheat) and oilseed (rapeseed, sunflower, poppy and soybean). Comparison of investigated genera was done.

Biosynthesis of 5,6-dimethylbenzimidazole from [1'-14C,5-15N]6,7-dimethyl-8-ribityllumazine

“…Renz (1970) has reported that [14C]riboflavin is an efficient precursor of the DBI moiety of vitamin Bi2 in broken cell preparations of P. shermanii. It has also been established that P. shermanii cultures produce riboflavin (Janicki et al, 1966). The labeling results reported here, as well as earlier labeling results from the 6,7-[14C]dimethyl-8-ribityllumazine precursor, are consistent with two reasonable biosynthetic pathways.…”
