D-Methionine CAS NO 348-67-4 C5H11NO2S

Introduction:

D-methionine is an optically active form of methionine having D-configuration. It is a methionine and a D-alpha- Amino Acid . It is a conjugate base of a D-methioninium. It is a conjugate acid of a D-methioninate. It is an enantiomer of a L-methionine. 

Methionine is one of nine essential amino acids in humans (provided by food), Methionine is required for growth and tissue repair. A sulphur-containing amino acid, methionine improves the tone and pliability of skin, hair, and strengthens nails. Involved in many detoxifying processes, sulphur provided by methionine protects cells from pollutants, slows cell aging, and is essential for absorption and bio-availability of selenium and zinc. Methionine chelates heavy metals, such as lead and mercury, aiding their excretion. It also acts as a lipotropic agent and prevents excess fat buildup in the liver. (NCI04)
