从六种不同动物中所制得之胰岛素其中氨基酸的排列在以前已有所报导。其不同点仅发现在A链的8.9.10位置上三种氨基酸的不同。如果知道人体胰岛素与其他动物胰岛素之间的差别则是很有意义的,因为可将它们作为代用品。结晶的人体胰岛素是从屍体的胰脏而制得的,B部分氨基酸排列的测定如以前所述,即 Insulin produced from six different animals, the amino acid arrangement of which has been previously reported. The difference is only found in the A chain 8.9.10 position of the three amino acid differences. If you know the difference between human insulin and other animal insulin is very significant, because they can be used as a substitute. Crystallized human insulin is prepared from the body’s pancreas and the measurement of the amino acid sequence of Part B is as described previously
