Fat+and+Water+Soluble+Vitamins

=Fat- and Water- Soluble Vitamins=

Different vitamins have different chemical structures, which result in different solubilities. The polar structure of vitamins B and C make them water soluble. For that reason, they cannot be stored in the body. However, vitamins A, D, E, and K can be stored in fat: their long, nonpolar carbon chains make them soluble in fat. A majority of the fat soluble vitamins are brought into the body by fatty foods and fish oils. Therefore, a little bit of fat is needed in a daily diet. Although, the liver can store enough of the fat soluble vitamins to last several months. However, if the body has too much vitamin A or D, the extra vitamins can actually damage the liver.
