概要
- 論文の詳細を見る
Itin sulfate was successfully crystallized as the calcium salt from the mucoproteins of a sea cucumber, Cucumaria japonica, by the procedure shown in Fig. 1. The chemical com-position of the crystalline itin sulfate was found to be quite similar to chondroitin sulfate prepared by the SCHUBERT method, being composed of each equimole of hexosamine, hexuro-nic acid and sulfur. The values of nitrogen and sulfur were however slightly higher in the former than in the latter (Table 1). The component sugars of the compound were identified by paper chromatography as gal-actosamine and glucuronic acid (Table 2) and the compound bears similarity to the chondroitin sulfate.
