Document Summary
Conditionally essential: nutrients produced by symbiotic bacteria (vitamin k), non-existent in babies therefore they are often given supplemental injections. Non-essential nutrients: synthesized by our bodies from scratch = glucose (gluconeogenesis) starch, lipids (lipogenesis) Out of 20, half are essential ( histidine, isoleucine, leucine, lysine, methionine, Essential amino acids and fatty acids: needed for protein synthesis. Phenylalanine, tryptophan, valine ), two are conditionally essential: arginine (arg) and. Many fa are not made by our body, especially w-3 and w-6 (refers to position of c=c) Lack of essential amino acids can cause mental and physical retardations, stunted growth and edema. Ascorbic acid - synthesized by most animals. Required for the synthesis of collagen (it assists in the production hydroxyproline from. Mutations cause the inability to make vitamin c - mutation in the glo gene causes the proline) lack of the enzyme l-gulono-y lactone oxidase. Only exist as chemical elements and are usually in its ionic form.
