Ascorbic acid metabolism in rats fed high fat cholesterol diet. 1976

B Nambisan, and P A Kurup

The synthesis and catabolism of ascorbic acid has been studied in rats fed an atherogenic diet as also has the relation between the concentration of ascorbic acid and concentration of lipids in the tissues. The concentration of ascorbic acid was found to decrease in the serum, liver, spleen and adrenals, but not in the kidney, in the animals fed an atherogenic diet when compared with those fed normal diet. An inverse relationship was found between the concentration of ascorbic acid in the tissue and the concentration of lipids. The synthesis of ascorbic acid from D-glucuronalactone did not significantly differ in the liver and kidney, but decreased in the spleen in the animals fed the atherogenic diet. On the other hand, the catabolism of ascorbic acid significantly increased in the liver and spleen.

D010743	Phospholipids	Lipids containing one or more phosphate groups, particularly those derived from either glycerol (phosphoglycerides see GLYCEROPHOSPHOLIPIDS) or sphingosine (SPHINGOLIPIDS). They are polar lipids that are of great importance for the structure and function of cell membranes and are the most abundant of membrane lipids, although not stored in large amounts in the system.

D002784	Cholesterol	The principal sterol of all higher animals, distributed in body tissues, especially the brain and spinal cord, and in animal fats and oils.	Epicholesterol
D002791	Cholesterol, Dietary	Cholesterol present in food, especially in animal products.	Dietary Cholesterol
D000311	Adrenal Glands	A pair of glands located at the cranial pole of each of the two KIDNEYS. Each adrenal gland is composed of two distinct endocrine tissues with separate embryonic origins, the ADRENAL CORTEX producing STEROIDS and the ADRENAL MEDULLA producing NEUROTRANSMITTERS.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

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.
