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

• branched: Val, Leu, Ile

• 

  Valine

• 

  Leucine

• 

  Isoleucine

• aromatic: Phe, Trp

• 

  Phenylalanine

• 

  Tryptophan

• basic (basic): His and Arg (both essential only in childhood or in critical states), Lys

• 

  Histidine

• 

  Arginine

• 

  Lysine

• with sulfur content: Met

• 

  Methionine

• with OH− group: Thr
