Abstract

Distribution of [3-14C] tryptophane in rat tissues was studied as affected by sodium deficiency in diet. The tissues are found to accumulate tryptophane differently. Elimination of sodium from the diet decreases the intensity of [3-14C] tryptophane delivery to animal tissues. The in vitro experiments established the dependence of the [3-14C] tryptophane incorporation into proteins on the sodium concentration in the medium. Its deficiency and redundancy lower the intensity of tryptophane incorporation into proteins.

摘要

研究了饮食中钠缺乏对[3-14C]色氨酸在大鼠组织中分布的影响。发现各组织对色氨酸的积累情况不同。从饮食中去除钠会降低[3-14C]色氨酸向动物组织输送的强度。体外实验确定了[3-14C]色氨酸掺入蛋白质的过程对培养基中钠浓度的依赖性。钠缺乏和过量都会降低色氨酸掺入蛋白质的强度。
