19 or 20

amino acids?? 20 amino acids
Amino acids... Like this Protien>amino acids>RNA nucleotides The amazing thing is that only 20 different amino acids exist in the human body yet mix/match/repeat to make all of the protiens in the body!

Amino acids are the building blocks of proteins.Amino acids are broadly classified into the following categoriesPolarNon-polarHydrophobicHydrophilicAliphaticAromaticSince there are so many classes and only 20 amino acids, we observe a considerable overlap between classes. Which means one amino can be simultaneously classes into two categories (like non polar and aromatic)standard amino acid (a building block of proteins)
