In normal cells, oxaloacetate is converted to aspartate by transamination which further converts into L-asparagine by asparagine synthetase which converts the carboxy group to amide group in the side chain.

(2006), MHA is converted into L-Met through two pathways: alpha carbon oxidation and transamination. The authors showed that there is a conversion of MHA into L-Met in the small intestines of chickens and MHA provides higher cysteine concentrations in relation to DLM, suggesting that MHA is preferably shifted through the transsulfuration route and subsequent formation of sulfate ions.
