Amino Acids (FBLT)

Amino acids are the basic structural component of proteins and peptides. They contain at least one amino- (–NH 2) and one carboxyl (–COOH) group.


From the point of view of biosynthesis, we can divide them into:

  1. Non-essential, which the body can synthesize: Gly, Ala, Pro, Ser, Tyr, Cys, Asp, Asn, Glu, Gln
  2. Essential, which we must take in food
