Where do amino acid come from?

Answer 1

AMINO ACIDS are found in all foods except oil. Despite claims to the contrary, all vegetables, legumes, and grains contain all the essential amino acids. They may not contain high amounts of some, but, if combined with another vegetable source, all the essential amino acid requirements are met. There are about eighty amino acids found in nature, but only twenty to twenty-nine are required for human growth. This figure depends upon the source consulted but most agree the figure is twenty or twenty-one. Once again, depending on the source, eight to ten amino acids are considered essential for life.
