    Vitamin D exerts its genomic effects through a nuclear gene transcription factor, the vitamin D receptor (VDR), while metabolism of vitamin D both to its biologically active form, as well as to its excretory product, plays a major role in determining biological activity at the tissue level. Vitamin E is found in a variety of foods including almonds, vegetable oils, and cereals. The form that is best known for its role in human health is alpha-tocopherol, which is abundant in olive and sunflower oils and is the predominant form in the European diet.

    It regulates cellular metabolism and cell division. Coupled with its role in DNA and RNA, it supports healthy tissue growth and the regeneration of red blood and immune cells. It’s essential for fetal development, so it’s critical for pregnant women and those who . Vitamin E is a fat-soluble vitamin that acts as an antioxidant that protects the fatty components of cell membranes, as well as LDL-cholesterol, vitamin A, and our lungs, from oxidative damage. It also assists the development of nerves and muscles, enhances immune function, and improves the absorption of vitamin A, if intake of vitamin A is low.

    Summary of the role of vitamin E in human metabolic processes. A large body of scientific evidence indicates that reactive free radicals are involved in many diseases, including heart disease and cancers (1).Cells contain many potentially oxidizable substrates such as polyunsaturated fatty acids (PUFAs), proteins, and DNA. Gabe is a nutrition student who is learning that a balanced diet involves consuming foods that have a variety of vitamins in them every day. The primary function of vitamin C in cellular metabolism is to. act as nonspecific reducing agent (electron donor. A major role of folate in cellular metabolism is the. synthesis of purine and.

Cellular signaling The role of vitamin E in cellular signaling, especially in relation to protein kinase C, has been studied intensively by Azzi’s group. [ 55 ] α–Tocopherol inhibits smooth muscle cell proliferation [ 56 ], decreases protein kinase C activity [ 57 ], increases phosphoprotein phosphatase 2A activity [ 58 ], and controls expression of the α–tropomyosin gene.

[ 55 ]. Importantly, these mechanistic aspects of vitamin E metabolism have recently been identified to play a role in the health-promoting effects of this vitamin, affecting lipid metabolism and detoxification processes, immune cell modulation, and cardiovascular protection : Pierangelo Torquato, Rita Marinelli, Desirée Bartolini, Danilo Giusepponi, Gabriele Cruciani, Lydia.

α-Tocopherol is the most potent antioxidant and highly active form of vitamin E. Because it is lipid soluble, vitamin E primary protects lipid molecules from oxidative shock, and hence is considered to be a major membrane-bound antioxidant employed by the cell (Burton Cited by: 2.

Vitamin E and its function in membranes. Wang X(1), Quinn PJ. Author information: (1)Division of Life Sciences, King's College London, UK. Vitamin E is a fat-soluble vitamin. It is comprised of a family of hydrocarbon compounds characterised by a chromanol ring with a phytol side chain referred to as tocopherols and by:   Vitamin E has a recognized leading role as a contributor to the protection of cell constituents from oxidative damage, although the health benefits of VE probably go far beyond its involvement as a radical scavenger.

A full understanding of the metabolic targets of VE or its derivatives, as well as their mechanism of action, is still lacking. When vitamin E increases the expression or activity of enzymes involved in its own degradation, it is possible that vitamin K metabolism is also enhanced under elevated vitamin E status; this may lead to higher rates of vitamin K excretion and in turn to vitamin K deficiency Cited by: 5.

TOPIC 3. VITAMIN METABOLISM Vitamins are organic compounds that function as metabolic catalysts~ usually in the form of coenzymes (Smith ). Vitamins may be divided into a fat-soluble group (A~ D~ E, and K) and a water-soluble group (the B complex and C).

Vitamins have essential roles in metabolic processes. Vitamins is aimed at nutritionists, biochemists, physiologists and physicians whether they be researchers, teachers or students. Food scientists, food technologists and many others working in the health professions will also find much of use and interest in the book.

Vitamin E is a strong antioxidant and it helps prolong the life of red blood cells, it plays an essential role in cellular respiration. It protects biological membranes such as those found in the nerves, muscles, and cardiovascular system. Recent data question previous concepts and trigger renewed interest, like as the relationship between retinol plasma level and outcome in hemodialysis patients, the disappointing effects of vitamin E supplementation, the role of vitamin K in bone mineral metabolism, the use of niacin as a phosphate binder, and the influence of vitamin C and B6 on oxalate metabolism in renal failure.

Sang-Min Jeon and Eun-Ae Shin at Ajou University in South Korea review research on links between cancer and vitamin D metabolism. Vitamin D is best known for its role. As vitamin E deficiencies can lead to skeletal muscular disease and the vitamin is located in the cell membrane, recent research on the biological role of vitamin E has focused on a potential function in muscle cell.

Muscle also generates oxidants during cellular metabolism, which increases during exercise. Vitamin B6. Also called pyridoxine, occurs widely in foods like wholemeal bread, bananas, yeast extract, nuts, liver and pulses. Functions. Vitamin B6 plays a role in the metabolism of protein, carbohydrates and fats, the production of neurotransmitters and the formation of nicotinic acid.

It is vital for maintaining a healthy nervous system. role of the B vitamin family in maintaining mitochondrial energy metabolism and how mitochondria in their role as the cellular organelles responsible for energy metabolism are compromised by a deficiency of any B vitamin.3 As with the B vitamins, the role of certain minerals in energy metabolism is the subject of increasing interest.

For instance, chronic treatment of young rats by RA increases basal corticosterone concentration. However, most of the recent literature refers to its possible use or role in pituitary or adrenal tumours.
