explain essential and non essential amino acids




plzzz reply​

Answer 1

Answer:

Nonessential amino acids can be made by the body, while essential amino acids cannot be made by the body so you must get them from your diet. You must have all of the amino acids so your body can build the wide variety of proteins it needs. Protein is needed for the repair, growth and maintenance of the cells.

There are 11 nonessential amino acids: They are arginine, glutamine, tyrosine, cysteine, glycine, proline, serine, ornithine, alanine, asparagine, and aspartate.

Nine out of the 20 amino acids are essential, but adults only need to obtain eight of them: valine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine and tryptophan. The ninth amino acid -- histidine -- is only essential for infants.
