説明
1. Total sugar content of crystalline phycoerythrin was estimated to be 4.78 per cent (28 moles per 105g.) by acid hydrolysis, and photometry with orcinol.<br> 2. More than two thirds of the sugar components seemed to be uronic acid-like substance which was liberated from phycoery-thrin only with difficulty by acid hydrolysis or by methanolysis.<br> 3. Three neutral sugars, xylose, arabinose and galactose were isolated in yields of 0.46, 0.24 and 0.40 per cent from phycoerythrin, respectively, together with much less amount of uronic acid-like substance and of an un-identified neutral sugar.<br> 4. No glucosamine, galactosamine and 3, 6-anhydrogalactose could be detected in phycoerythrin.<br> 5. A chromopeptide, P-12a derived from phycoerythrin with pepsin, also contained xylose, arabinose and galactose residues.<br> This work was performed in the Institute of Chemistry, Faculty of Industrial Arts, Kyoto Technical University, under the direction of Prof. C. Araki and in the Institute for Protein Research, Osaka Uni-versity, under the direction of Prof. S. Akabori.<br> The author wishes to express her sincere gratitude to Prof. C. Araki and Prof. S. Akabori for their Constant interest and encouragement.<br> She also wishes to thank Mr. Arai for his valuable suggestions and technical help and Miss K. Okada for technical assistance.
