A scheme for coordination of sorbitol, pentose phosphate, and glycolysis pathways of carbohydrate metabolism in tissues of the silkworm is proposed. The scheme considers the functional role of multiple forms of glucose-1-phosphatase, acid phosphatase, and NAD⁺- and NADP⁺-dependent sorbitol dehydrogenases isolated from the fat body, hemolymph, and intestinal wall of the silkworm.
