If you're like most kids, you've probably heard at least one parent say, "Don't forget to take your vitamin! Vitamins and minerals are substances that are found in foods we eat. Your body needs them to work properly, so you grow and develop just like you should. When it comes to vitamins, each one has a special role to play. For example:.
Much has been learned about the function of the fat-soluble vitamins in recent years. Their mechanisms are divergent ranging from a role in transcription of DNA or differentiation to a direct enzymatic activation of the gamma-carboxylation of glutamate residues of a preexisting protein. Thus the only resemblance so far among these physiologically active agents is their lipid solubility. However, in general the fat-soluble vitamins play important roles in specialized functions carried out by highly differentiated organisms. Most users should sign in with their email address.

Rochester, Minn. Karrer and associates isolated it in and determined its structure, but effective syntheses of vitamin A were achieved by Milas 1 and others only during the last five years. The vitamin is an alcohol and hence is not itself saponifiable. Evidence has been presented indicating that vitamin A occurs in more than one form. The form that predominates in the tissues of salt water fish and mammals has been designated as vitamin A 1 and the form which predominates in the tissues of fresh water fishes as vitamin A 2. Both forms appear to exert similar functions, although vitamin A 1 is considerably more effective in mammals than vitamin A 2. The international unit of vitamin A has been fixed as the activity of 0.
The tables below list the vitamins , what they do in the body their functions , and their sources in food. Water-soluble vitamins travel freely through the body, and excess amounts usually are excreted by the kidneys. The body needs water-soluble vitamins in frequent, small doses. These vitamins are not as likely as fat-soluble vitamins to reach toxic levels.
We take vitamins and supplements to bolster those we get from the foods we eat and the sunlight we are exposed to. They are absorbed into the body in different ways and excreted from the body at different rates. We can broadly classify them as being either water-soluble or fat-soluble. Water-soluble vitamins are those that are dissolved in water and readily absorbed into tissues for immediate use. Because they are not stored in the body, they need to be replenished regularly in our diet.
