They are stored until theyre required which consequently means they generally dont need to be ingested as frequently.
Vitamin a molecular structure. Vitamin A is effective for the treatment of Vitamin A deficiency. Vitamin A refers to a group of fat-soluble substances that are structurally related to and possess the biological activity of the parent substance of the group called all-trans retinol or retinol. Vitamin A plays vital roles in vision epithelial differentiation growth reproduction pattern formation during embryogenesis bone development hematopoiesis and.
Chemical structure of Vitamin A or Retinol. Vitamin A regulates cell and tissue differentiation and growth. It is toxic in high doses.
Humans can synthesize vitamin A from the precursor molecule beta carotene. Structures and Functions of Vitamins. Table 1 below shows the structures and functions of several fat- and water-soluble vitamins.

Vitamins and minerals are nutrients required in very small amounts for essential metabolic reactions in the body. Some diseases caused by vitamin deficiencies such as scurvy have been recognized since antiquity but it was only in the 20th century that systematic nutritional studies identified the chemical structures of many of these essential. Vitamins are an important part of our diet but you probably havent given a great deal of thought to their chemical structures.
This graphic shows chemical structures for all 13 vitamins. Though there can be some variability in these structures in sources of the vitamins these are generally representative. They perform a range of roles in the body.
Below is a brief discussion and a look at the evidence for taking vitamin. PubChem is the worlds largest collection of freely accessible chemical information. Search chemicals by name molecular formula structure and other identifiers.

Vitamin E alpha tocopherol is a fat soluble vitamin and potent antioxidant that is believed to be important in protecting cells from oxidative stress regulating immune function maintaining endothelial cell integrity and balancing normal coagulationThere is no evidence that vitamin E in physiologic or even super-physiologic high doses causes liver injury or jaundice. Vitamin E is a plant-derived lipid-soluble substance whose molecular structure is comprised of a chromanol ring with a side chain located at the C2 position.
Vitamin E refers to a group of eight different compounds. α- β- γ- and δ-tocopherols and the corresponding four tocotrienols. The four tocopherols have a saturated phytyl side chain while tocotrienols have an unsaturated isoprenyl side chain.
Vitamin K C31H46O2 CID 5280483 - structure chemical names physical and chemical properties classification patents literature biological activities safety. Currently there are 13 recognised vitamins. Vitamins A to E including a range of B vitamins and vitamin K.
Generally we can stick all of the vitamins into two broad categories. The fat soluble vitamins vitamins A D E and K can be stored by our bodies in the liver or in fatty tissues. They are stored until theyre required which consequently means they generally dont need to be ingested as frequently.

Vitamin A acetate Drug Entry Vitamin A. Retinol and derivatives of retinol that play an essential role in metabolic functioning of the retina the growth of and differentiation of epithelial tissue the growth of bone reproduction and the immune response.
Dietary vitamin A is derived from a variety of carotenoids found in plants. It is enriched in the liver egg yolks and the fat component of dairy products. Pyridoxine is the 4-methanol form of vitamin B6 an important water-soluble vitamin that is naturally present in many foodsAs its classification as a vitamin implies Vitamin B6 and pyridoxine are essential nutrients required for normal functioning of many biological systems within the body.
While many plants and microorganisms are able to synthesize pyridoxine through endogenous biological. Computed by PubChem 21 PubChem release 20190618 XLogP3-AA. Computed by XLogP3 30 PubChem release 20190618 Hydrogen Bond Donor Count.

Ergocalciferol is considered the first vitamin D analog and is differentiated from cholecalciferol by the presence of a double bond between C22 and C23 and the presence of a methyl group at C24. Vitamin A or retinolhas a structure depicted to the right. Retinol is the immediate precursor to two important active metabolites.
Retinal which plays a critical role in vision and retinoic acid which serves as an intracellular messenger that affects transcription of a number of genes.
