The questions based on the compound homocysteine are to be answered. Concept introduction: Homocysteine is an amino acid. Amino acid is the compound which comprises amino ( − NH 2 ) group and carboxyl ( − COOH ) functional group . This compound is formed during the process of metabolism of amino acids. This is homologue of cysteine. Both cysteine and homocysteine are amino acids. Basically all proteins are made-up of amino acids. When proteins break down, the amount of one of the amino acids like homocysteine is increased. This causes blood clots or some other problems and as a consequence risk of heart attack also increases. To determine: The structural differences between homocysteine and cysteine.
