The amino acids are the building blocks of proteins.Its like many bricks combining to form a wall.Bricks are the amino acids and wall formed is the protein.

The general formula of an amino acid is R-CH-COOH

                                                                     |

                                                                     NH2

When two amino acids combine together,(-NH2 group combines with -COOH group) a peptide linkage is formed.

Numerous amino acids combine together to form a polypeptide.

Many polypeptides join to form a protein.

Protein is essentially a polypeptide chain.

Ther are basically 20 amino acids which combine in different arrangement to form different proteins.

Some of the amino acids are glycine,alanine,valine,isoleucine,leucine,lysine,phenylalanine,threonine,trypthophan,etc...........
