The Structure of methionine is to be drawn. Concept introduction: Many amino acids are linked together through amide bonds to form a biologically large molecule known to be proteins. Amino functional group is ( − N H 2 ) and carboxyl functional group is ( − C O O H ) and a R group is considered as side chain, when all these are bonded to same carbon atom. Endorphins are neurotransmitters. Enkephalins are biologically active part of endorphins.
