Measurements of blood and liver water-soluble vitamins and of their metabolites urinary excretion helped characterize these vitamins metabolism in rats with streptozotocin-induced diabetes. The liver levels of recovered ascorbic acid and total thiamin were virtually the same in diabetic and intact rats. Essential changes of riboflavin metabolism were revealed in diabetes: riboflavin urinary excretion was five times higher than that in intact animals, the blood serum levels being the same in health and disease, whereas liver riboflavin levels in diabetic rats had a trend to lowering. The activities of FAD-dependent hepatic enzymes were the same in both groups. 4-pyridoxylic acid excretion was increased and 1-methylnicotinamide excretion reduced in diabetic rats.

D009536 Niacinamide An important compound functioning as a component of the coenzyme NAD. Its primary significance is in the prevention and/or cure of blacktongue and PELLAGRA. Most animals cannot manufacture this compound in amounts sufficient to prevent nutritional deficiency and it therefore must be supplemented through dietary intake.

D001205 Ascorbic Acid A six carbon compound related to glucose. It is found naturally in citrus fruits and many vegetables. Ascorbic acid is an essential nutrient in human diets, and necessary to maintain connective tissue and bone. Its biologically active form, vitamin C, functions as a reducing agent and coenzyme in several metabolic pathways. Vitamin C is considered an antioxidant.

D012256 Riboflavin Nutritional factor found in milk, eggs, malted barley, liver, kidney, heart, and leafy vegetables. The richest natural source is yeast. It occurs in the free form only in the retina of the eye, in whey, and in urine; its principal forms in tissues and cells are as FLAVIN MONONUCLEOTIDE and FLAVIN-ADENINE DINUCLEOTIDE.
