Abstract
1. D-Gluconic acid and D-ribose are degraded well accompanied with phosphorylation by both adapted and inadapted cells for ascorbic acid, whereas other pentoses, e.g., DL-xylose and DL-arabinose, are not matabolized.
2. It was assumed by successive adaptation that AsA is partially degraded through araboascorbic acid through the Warburg-Dickens-Cohen pathway. Araboascorbic acid is also assumed to proceed through the above pathway.
