Degradation of the sycamore cell wall by hydrazinolysis yielded soluble glycopeptides. The peptide portion of the predominant glycopeptide was shown to be cyclic (4-trans-hydroxy-l-prolyl)-4-trans-hydroxy- l-proline. From this structure and the composition of the major glycopeptide it was deduced that only short oligosaccharides are attached to the hydroxyprolyl residues of the wall glycoprotein. Detailed evidence for the structure of the peptide is given in a supplementary paper that has been deposited as Supplementary Publication SUP 50020, at the National Lending Library for Science and Technology, Boston Spa, Yorks.

通过肼解作用降解梧桐细胞壁可产生可溶性糖肽。已表明主要糖肽的肽部分为环状（4-反式羟基-L-脯氨酰基）-4-反式羟基-L-脯氨酸。根据这一结构和主要糖肽的组成可以推断，只有短寡糖与壁糖蛋白的羟脯氨酰残基相连。肽结构的详细证据见一篇补充论文，该论文已作为补充出版物SUP 50020存放在英国约克郡波士顿温泉市国家科技出借图书馆，邮编LS23 7BQ，可按《生物化学杂志》（1973年）第131卷第5期所示条件从该处获取复印件。
