متن کاملTransporters in plant sulfur metabolism
Sulfur is an essential nutrient, necessary for synthesis of many metabolites. The uptake of sulfate, primary and secondary assimilation, the biosynthesis, storage, and final utilization of sulfur (S) containing compounds requires a lot of movement between organs, cells, and organelles. Efficient transport systems of S-containing compounds across the internal barriers or the plasma membrane and ...
متن کاملThe Metabolism of Sulfur
The relation of the cystine of the diet to the growth and composition of the hair of young white rats has been established (l-3). In the absence of adequate amounts of dietary cystine, optimal growth of the hair was not observed and the cystine and sulfur contents of the hair were lower than those of rats maintained on diets supplying ample amounts of cystine. The ingestion of cystine in quanti...
متن کاملThe Metabolism of Sulfur
In previous studies (1, 2, 3) one of us (L.) has reported experiments which are concerned with the oxidation of sulfur in the cystine molecule. It was demonstrated that if deamination of cystine be prevented by “blocking” the amino group (as in phenyluraminocystine (1) or dibenzoylcystine (3) ), the sulfur of the molecule was not oxidized normally and was excreted in the urine in large part in ...
متن کاملThe Metabolism of Sulfur
The extent of the oxidation of the sulfur of the amino acid, cystine, by the animal organism has been the subject of frequent study (1, 2). It has been shown that the sulfur of cystine administered in moderate quantities is oxidized readily and excreted in bhe urine chiefly as sulfate sulfur. Variable recoveries of the sulfur of cystine when fed are frequently obtained, owing presumably to t,he...
