What are some examples of amino acids?

Alanine - ala - A
Arginine - arg - R
Asparagine - asn - N
Aspartic acid - asp - D
Cysteine - cys - C (Only amino acid with a Sulfur atom)
Glutamic acid - glu - E (Amino acid that codes of normal RBCs)
Glycine - gly - G
Histidine - his - H
Isoleucine - ile - I
Leucine - leu - L
Lysine - lys - K
Methionine - met - M (First amino acid to be produced at ribosome)
Phenylalanine - phe - F
Proline - pro - P
Serine - ser - S
Threonine - thr - T
Tryptophan - trp - W
Tyrosine - tyr - Y
Valine - val - V (Amino acid that codes for sickle-cell anemia)

Amino acids can be divided into two categories: isomers known as right-handed and left-handed amino acids. Generally speaking, only the latter is utilized.

The nine essential amino acids are histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. Essential amino acids are those that the body cannot produce on its own, so it must consume those molecules from food to meet the requirement.
