L-Mimosine (-(3-Hydroxy-4-Pyridone-1-yl)-L-Alanine)

matter in the seed has limited its use as a livestock feed since mimosine and its degradation products 3-hydroxy-4-(1H )-pyridone (3,4-DHP) and 2,3-dihydroxypyridine (2,3-DHP) have been known to be toxic to many species (Fig. 1) . Ingestion of mimosine

二肽的概念与二肽合成的个人心得体会

基连在连有羧基的碳上)中的氨基于羧基脱水缩合而成的。其中只含一个肽键即-CO-NH-。可水解。 肽大多性质不稳定，长期贮存宜防潮，放在4℃以下的地方。 医学和商用价值 活性肽，与营养，荷尔蒙、酵素抑制、调节免疫 、抗菌、抗病毒、抗氧化有非常紧密关系。 合成二肽工作中些许心得 最近一直在做合成N-Boc-L-His-L-Thr-OMe的实验，刚读研一的我来到实验室，看着凌乱的玻璃仪器，油腻的桌面，而且旋蒸的压力一点也上不去，看到这些心就凉
