REGARDING METHIONINE

    Recent studies have focused largely on oxidative studies involving amino acids and other sulfur-containing organic compounds of great biological importance. Methionine is an optically         active essential amino acid with a lot of physiological roles in the body. Some of its metabolic products include cysteine, homocysteine, and hypotaurine. It is obtained from dietary food in the body since the body does not synthesize the required methionine.  Methionine sulfoxide is the oxidation product of methionine in the body and its deposition has been linked to modification of protein surface hydrophobicity, a process that is known to accelerate aging. There has been a recent alert (Science, 1997) over possible dangers than can arise from excess homocysteine in the human body. Homocysteine is an important  product derived from methionine metabolism.
