together with a process for producing N-glycosides of aldose and ketose sugars containing from 5 to 7 carbon atoms in the sugar moiety by reacting in an inert solvent an N-glycoside forming base with a 3-O-acyl ketose, 2-O-acyl aldose or a trityl derivative of those acylated sugars that...
Cleavage of N-Glycosidic Linkage in Peptide--lysyl-N-glycosides by Ion Exchange Resin 来自 国家科技图书文献中心 喜欢 0 阅读量: 18 作者: S Adachi 摘要: IT is well known that the sugar components of amino-acid-glycosides are not always detected in the acidic hydrolysates; this is in ...
