Amino acids are monomers of proteins. These are substituted methanes and has a variable group R attached to the carbon. Due to presence of R group various types of amino acids are formed. Cysteine and Methionine are Sulphur containing amino acids. Tyrosine are amino acids with benzene ring. Glutamic acid is acidic and that means have acidic group. Serine has alcoholic group.
