摘要:摘要 建立了在基本培养基中培养这种硫酸盐还原菌的过程中特异标记普通脱硫弧菌宫崎f的四血红素蛋白细胞色素c 3 的条件.苯丙氨酸和酪氨酸残基的氘化效率超过 85%.细胞色素 C 3 具有九个组氨酸,三个酪氨酸和两个苯丙胺残基.八个组氨酸咪唑与四个血红素基团连接.使用氘代细胞色素 C 3,鉴定了完全氧化状态下苯丙氨酸和酪氨酸残基的芳香质子信号.然而,一个苯丙氨酸残基的信号缺失,暂时将其归于 Phe20.his67 的芳香质子信号也被指定为 P 2 H 滴定.它的 Pk 1 远高于游离组氨酸残基的 Pk 1.

标题 :Composition to improve athletic performance by supporting muscle protein synthesis and mental focus
发明人：WOLFE ROBERT REESE; WOLFE FREDERICK LEE
权利人:The Amino Company LLC
摘要:The present invention generally relates to compositions and methods for supporting exercise performance or activities of daily living. The compositions described herein are pharmaceutical or nutritional compositions suitable for enhancing exercise performance. The compositions are based on a specially formulated mixture of essential amino acids (EAAs) with additional components. The compositions target support of muscle protein synthesis and reduction of muscle breakdown during exercise, increasing muscle blood flow during exercise, decreasing the perception of fatigue by supporting optimal availability of neurotransmitter precursors, providing energy for rapids bursts of exertion during exercise, and maintaining adequate electrolyte balance during exercise.
