High-performance liquid chromatography (HPLC) coupled in-line with mass spectrometry (MS) permits rapid and specific identification and quantification of N -acyl-l -homoserine lactones (AHLs) and 4-hydroxy-2-alkylquinolines (HAQs

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
