There are 3 groups amino acids can be divided in. Those include:
ESSENTIAL AMINO ACIDS
Essential proteins can’t be created by the body. As a result, they need to come from food.The 9 essential proteins are: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.
NONESSENTIAL AMINO ACIDS
Nonessential means that our anatomical bodies produce those amino acids, even when we don’t obtain them from the food we eat. Nonessential amino acids include: alanine, arginine, asparagine, aspartic acid, cysteine, glutamic acid, glutamine, glycine, proline, serine, and tyrosine.
CONDITIONAL AMINO ACIDS
Conditional amino acids are not essential, except in times of illness and stress. Arginine, cysteine, glutamine, tyrosine, glycine, ornithine, proline, and serine are all conditional amino acids.
