CatabolicPathwaysforArginineHistidineGlutamateGlutamine,andProline
Glutamine is converted to glutamate by glutaminase or several other enzymes by the removal of the amide nitrogen. Proline is first converted to a Schiff base and then converted by hydrolysis to glutamate-5-semialdehyde. All of these changes occur on the same carbon. Arginine and histidine contain 5adjacent carbons and a sixth carbon attached through a nitrogen attom. The catabolism of these amino acids is thus slight......阅读全文

构成蛋白质氨基酸有哪些类型
甘氨酸 (Glycine, Gly)：是分子量最小的氨基酸，因其侧链仅为一个氢原子，从而使得其在蛋白质结构中具有极大的灵活性。 丙氨酸 (Alanine, Ala)：具有较小的疏水性侧链，使其能够在蛋白质内部稳定存在。 缬氨酸 (Valine, Val)：是一个分支链氨基酸，其较大的疏水性侧

关于脉络膜视网膜环状萎缩的治疗介绍
鉴于发病机制和生化研究，发现脉络膜视网膜环状萎缩是由于先天性某种酶的缺乏，并发现这种酶是0KT、0AT，由于酶缺乏鸟氨酸不能转化为谷氨酸而存在于血液内，并引起各种临床表现，因此本病可试用几种治疗方法。 限制鸟氨酸转化 主要限制精氨酸（arginine）饮食量，可降低血浆鸟氨酸水平。鸟氨酸不是
