摘　　要：本文根据胶原，改性胶原及模拟物与稀土（ＲＥ）作用的结果，认为在低ｐＨ范围内稀土主要与胶原的羧基结合，在较高的ｐＨ下（ｐＨ＞５．５），也与氨基结合。同时在较高ｐＨ下也有少量的稀土与肽基及羟基结合。According to the result of collagen,denaturated collagen and substitutes acted by RE,it is suggested that RE bonds mainly with cartoxyl groups in lower pH region,and also with amino groups at higher pH value (such as pH>5 5),at the same time small RE quantities were bonded on peptidyls and hydroxyl groups.
