The 20 amino acids found in proteins are: Alanine, Arginine, Asparagine, Aspartic Acid, Cysteine, Glutamic Acid, Glutamine, Glycine, Histidine, Isoleucine, Leucine, Lysine, Methionine, Phenylalanine, Proline, Serine, Threonine, Tryptophan, Tyrosine, and Valine.

What are the 20 amino acids and structure?

The 20 amino acids are the building blocks of proteins. They are composed of a central carbon atom attached to an amino group (NH2), a carboxyl group (COOH), and a side chain (R group). The R group varies for each amino acid, and determines its chemical properties. The structure of an amino acid is shown below:


The 20 amino acids are:

1. Alanine (Ala)
2. Arginine (Arg)
3. Asparagine (Asn)
4. Aspartic acid (Asp)
5. Cysteine (Cys)
6. Glutamine (Gln)
7. Glutamic acid (Glu)
8. Glycine (Gly)
9. Histidine (His)
10. Isoleucine (Ile)
11.

What are the 20 amino acids your body needs?

Your body needs twenty different amino acids to function properly. These amino acids are: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, valine, arginine, cysteine, glycine, proline, tyrosine, alanine, aspartic acid, glutamic acid, serine, asparagine and glutamine. Some of these amino acids are produced naturally in your body, while others must be obtained through your diet.
