Dimethylamine is an organic compound with the formula (CH 3) 2 NH. This secondary amine is a colorless, flammable gas with an ammonia -like odor. Dimethylamine is commonly encountered commercially as a solution in water at concentrations up to around 40%.
Thiamine is one of the B vitamins and is also known as vitamin B 1. [3] [4] It is a cation that is usually supplied as a chloride salt.It is soluble in water, methanol and glycerol, but practically insoluble in less polar organic solvents.
Vitamins are classified as either water-soluble or fat-soluble. In humans there are 13 vitamins: 4 fat-soluble (A, D, E, and K) and 9 water-soluble (8 B vitamins and vitamin C). Water-soluble vitamins dissolve easily in water and, in general, are readily excreted from the body, to the degree that urinary output is a strong predictor of vitamin ...
Physically it resembles the other forms of vitamin B 12, occurring as dark red crystals that freely form cherry-colored transparent solutions in water. Vitamin B 12 is the most chemically complex of all the vitamins. [6] The structure of B 12 is based on a corrin ring, which is similar to the porphyrin ring found in heme. The central metal ion ...
Vitamin A is a fat-soluble vitamin, a category that also includes vitamins D, E and K.The vitamin encompasses several chemically related naturally occurring compounds or metabolites, i.e., vitamers, that all contain a β-ionone ring. [4]
Vitamin D is a group of fat-soluble secosteroids responsible for increasing intestinal absorption of calcium, magnesium, and phosphate, along with numerous other biological functions. [1] [2] In humans, the most significant compounds within this group are vitamin D 3 (cholecalciferol) and vitamin D 2 (ergocalciferol). [2] [3]
Vitamin E is fat soluble, so dietary supplement products are usually in the form of the vitamin, esterified with acetic acid to generate tocopheryl acetate, and dissolved in vegetable oil in a softgel capsule. [3] For alpha-tocopherol, amounts range from 100 to 1000 IU per serving. Smaller amounts are incorporated into multi-vitamin/mineral ...
Riboflavin, also known as vitamin B 2, is a water-soluble vitamin and is one of the B vitamins. [3] [4] [5] Unlike folate and vitamin B 6, which occur in several chemically related forms known as vitamers, riboflavin is only one chemical compound.
