can the human body produce l-methionine
The sulphurous Î±-amino acid L-methionine is an essential amino acid. The human body is not able to manufacture it by itself. That means that a constant blood serum level level therefore has to be maintained through nutrition and diet. The main functions of L-methionine include the building of various protein molecules and the synthesis of the equally sulphurous amino acid L-cysteine.
