Amino acid

20 (or 21) amino acids function as the building blocks of protein and are classified as standard amino acids.

• your body can’t create 9 essential amino acids, you can get them all at once by eating complete proteins.
• your body creates conditionally essential amino acids except in times of stress.
• your body creates 11 non essential amino acid

Some authorities recognize a 21st amino acid, selenocysteine

• lysine
  • Lysine is an amino acid that plays major roles in protein synthesis, calcium absorption, and the production of hormones and enzymes. It’s also important for energy production, immune function, and collagen and elastin production (14).
• glycine
  • amino acid
• histidine
  • Your body uses this amino acid to produce histamine, a neurotransmitter that is vital to immune response, digestion, sexual function, and sleep-wake cycles. It’s critical for maintaining the myelin sheath, a protective barrier that surrounds your nerve cells (15).
• methionine
  • This amino acid plays an important role in metabolism and detoxification. It’s also necessary for tissue growth and the absorption of zinc and selenium, minerals that are vital to your health (11).
• phenylalanine
  •  Your body turns this amino acid into the neurotransmitters tyrosine, dopamine, epinephrine, and norepinephrine. It plays an integral role in the structure and function of proteins and enzymes and the production of other amino acids (7).
