About Beta CaroteneA natural precursor to Vitamin A.Mechanism of Action of Beta CaroteneBeta-carotene acts as the precursor of Vitamin A and in the body it is converted in to Vitamin A. Vitamin A is required for a variety of physiological functions in the body such as: - 1).Proper functioning of retina and formation of pigment Rhodopsin during dark adaptation. 2).promotes differentiation and maintains structural integrity of epithelia over the body and also retard the malignancies of epithelial structures.3).Promotes mucous secretion. 4).Inhibits keratinization, 5). Maintains proper bone growth, 6).Maintenance of spermatogenesis, 7).Supports foetal development, 8).Improves resistance to infection. It is required for proper antibody response, normal lymphocyte proliferation and killer cell function.Pharmacokinets of Beta CaroteneAbsorption: Completely absorbed normally. Steatorrhoea, bile deficiency, and protein poor diet adversely affects the absorption and absorption requires bile salts, pancreatic lipase, and dietary fat.
Distribution: Stored primarily as palmitate in kupffer`s cells in liver. Circulates in the form of specific alpha-1 protein; retinol binding protein and transported to cellular retinol binding protein of target cells.

About Vitamin CWater soluble vitamin, antioxidant.Mechanism of Action of Vitamin CVitamin C exerts it`s action by influencing the biologic oxidations and reductions used in cellular respirations. It directly stimulates collagen synthesis and maintains intracellular connective tissue. It involves in various metabolic reactions such as 1).Hydroxylation of praline and lysine residues of protocollagen which is essential for formation and stabilization of collagen triple helix, 2).hydroxylation of carnitine, 3).Conversion of folic acid to folinic acid, 4).biosynthesis of adrenal steroids, catecholamines, oxytocin, and ADH, 5).Metabolism of cyclic nucleotides and prostaglandins. Vitamin C is important in resistance to infections.Pharmacokinets of Vitamin CAbsorption: Well absorbed orally.
Distribution: Widely distributed both extracellularly and intracellularly, It crosses the placenta and also distributed in to the breast milk.

About Vitamin D3N/AMechanism of Action of Vitamin D3Vitamin D3 is a form of vitamin D. It is also called as Cholecalciferol.7-Dehydrocholesterol is the precursor of vitamin D3 and only forms the vitamin after being exposed to UV radiation.After exposure to the sun, cholecalciferol is sent to the liver to be hydroxylated where it becomes 25-Hydroxyvitamin D3.Next, it is sent to the kidney and once again hydroxylated becoming 1,25-Hydroxyvitamin D3. 1,25-Hydroxyvitmain D3 is the active form of vitamin D3, for this reason vitamin D is often referred to as a prohormone.Vitamin D exerts it`s action by influencing calcium homoeostasis. It increases the intestinal absorption of calcium and phosphate. It binds to the cytoplasmic Vitamin D receptor and translocates to the nucleus and thus increases the synthesis of specific m RNA and regulates protein synthesis. It increases the synthesis of a carrier protein for calcium called "calbindin" or calcium binding protein. Activation of Vitamin D receptor enhances endocytotic capture of calcium and it`s transport across duodenal mucosal cells in a vesicular form. Vitamin D promotes resorption of calcium and phosphate from bone by enhancing recruitment and differentiation of osteoclast precursors in the bone remodeling units. It helps in bone mineralization.Pharmacokinets of Vitamin D3Absorption: Well absorbed orally in the presence of bile salts, Malabsorption and steatorrhoea interfere with it`s absorption.
Distribution: Widely distributed in a protein bound form. It is stored in adipose tissue and liver.
Metabolism: It is hydroxylated in to both active and inactive metabolites and also metabolized in kidney.
Excretion: Metabolites are excreted mainly through bile.
