Vitamin K2 is a collective term for a series of terpene side chain compounds containing 2-methyl-1, 4-naphthoquinone nucleus and a different number of isoprene structural units at the C3 position. According to the carbon on the terpene side chain The number of elements can be divided into K2(10), K2(20), K2(35), K2(40), etc. Vitamin K2 (35) is vitamin K2 with 35 carbon elements on the terpene side chain; vitamin K2 (35) is also known as menadione-7, which is based on the fact that there are 7 isoprene on the terpene side chain The alkene side chain is named.

Vitamin A
Vitamin A is a group of unsaturated nutritional organic compounds, that includes retinol, retinal, retinoic acid, and several provitamin A carotenoids, and beta-carotene.Vitamin A has multiple functions: it is important for growth and development, for the maintenance of the immune system and good vision. Vitamin A is needed by the retina of the eye in the form of retinal, which combines with protein opsin to form rhodopsin, the light-absorbing molecule necessary for both low-light (scotopic vision) and color vision. Vitamin A also functions in a very different role as retinoic acid (an irreversibly oxidized form of retinol), which is an important hormone-like growth factor for epithelial and other cells.
Vitamin D2
Ergocalciferol (vitamin D2) is a form of vitamin D. Ergocalciferol is a secosteroid formed by a photochemical bond breaking of a steroid, specifically, by the action of ultraviolet light on ergosterol. Viosterol, the name given to early preparations of irradiated ergosterol, is essentially synonymous with ergocalciferol.
