an amino acid contains two different functional groups-

a basic amino group(NH2) 

an acidic carboxl group(COOH)

amino acids form polymers known as polypeptides via condensation polymerisation

an amino group of an amino acid reacts with the acid group of another amino acid to form a polymer chain

1+ long-chain polypeptides are known as proteins

uses of proteins:

-enymes work as catalysts speeding up body reactions

-haemoglobin in red blood cells transport oxygen around the body

-antibodies form part of the immue system and rid things eg bacteria

-majority of body tissue is…
