Amino Acids???

Question

How many of the 20 or so amino acids in the body require that they can produce themselves. Where does the body obtain the rest of the amino acids?

I need to see your source, too.

Answer 2

amino acid
n.

An organic compound containing an amino group (NH2), a carboxylic acid group (COOH), and any of various side groups, especially any of the 20 compounds that have the basic formula NH2CHRCOOH, and that link together by peptide bonds to form proteins or that function as chemical messengers and as intermediates in metabolism.

An organic compound composed of both an amino group and an acidic carboxyl group. Amino acids are the basic building blocks of proteins. There are 20 types of amino acids (eight are "essential amino acids" that the body cannot make and must therefore be obtained from food).

Hydrophilic and hydrophobic interactions of the proteins do not have to rely only on aminoacids themselves. By various posttranslational modifications other chains can be attached to the proteins, forming hydrophobic lipoproteins or hydrophilic glycoproteins.

Answer 3

About half can be made from various precursors; the other half must come from the diet. See previous responder for a list. The list differs among species; it is not the same for a human as for a dog or cat.

Answer 4

human cells can make the non essential amino acids.

The essential aa the body gets from its diet

essential aa are:
Phenylalanine
Valine
Tryptophan
Threonine
Isoleucine
Methionine
Histidine
Arginine
Lysine
Leucine
