L-组氨酸盐酸盐,一水

L-组氨酸盐酸盐,一水用途

【用途一】
营养增补剂。人体内合成速度较慢，为准必需氨基酸。可用于强化婴幼儿食品，外科手术后病人食品。用化学膨松剂制造面包时，添加组氨酸、亮氨酸、精氨酸可改善香味。
【用途二】
组织胺（histamine）的前体物质，依靠组氨酸脱羧酶（histidine decarboxylase）。

L-组氨酸盐酸盐,一水制备

1.由脱脂大豆水解物分离赖氨酸时的副产物。在碱性氨基酸中其碱性最弱，通过离子交换树脂柱，即能与其他碱性氨基酸分离。或使其形成难溶的汞盐、3，5-二氯苯磺酸盐等而分离。
2.由血红蛋白经用盐酸水解而得。
3.发酵法制取。

4.提取法

5.注射液制法如下。
