Basic concepts
erythrose
It contains two adjacent chiral carbon atoms (see chirality). Free erythrin has not been found in nature, and D-erythrin-4-phosphate is carbohydrate Intermediate of enzymatic conversion. D-Erythritose is a syrup like liquid, with the phenomenon of rotation change; The specific rotation is+1 ° → - 14.5 ° (3 days, water, C=11). L-Erythritose is also a syrup liquid with sweet taste,+11.5 ° →+30.5 ° (long-term balance, water, C=3). Neither D - nor L-Erythritose is fermented by yeast. D-erythrin is generally composed of D-arabinose Calcium carbonate is prepared by oxidation; L-erythrin can be determined by L-arabinose It is prepared by oxidation of calcium carbonate. An organic compound containing two adjacent chiral carbon atoms, such as the configuration of the chiral carbon atom equivalent to erythrin, is called the red configuration.
