Substitution of A1-glycine of insulin by L-amino acids yields in analogues with low biological activity. With D-amino acids in A1 biological activity is essentially retained. The influence of aliphatic, aromatic, acidic and basic alpha-D-amino acids as well as omega-amino acids in A1 on the biological effects in different test systems is studied and discussed.
将胰岛素的A1位甘氨酸用L-氨基酸取代会产生生物活性较低的类似物。而在A1位用D-氨基酸取代时,生物活性基本得以保留。研究并讨论了A1位的脂肪族、芳香族、酸性和碱性α-D-氨基酸以及ω-氨基酸对不同测试系统中生物效应的影响。
