Abstract
THE products of radiolysis of carbohydrates have been studied in great detail1: deoxycompounds have been found only by Kochetkov et al.2 and only as radiolysis products of α-methylglucose. My results indicate that deoxycompounds are also formed when unsubstituted mono and disaccharides, starch and cellulose powder are irradiated. Treatment with periodic acid converts deoxycompounds to malondialdehyde3, which can be determined with 2-methylindol4. This reagent gives a deep red colour with malondialdehyde, with a sharp absorption maximum at 555 nm.
