Methionine metabolism in mammals
Web6 dec. 2024 · Methionine is an essential amino acid in mammals. It is required for protein synthesis and is a central player in 1-carbon metabolism. In its activated form, S-adenosylmethionine (SAM), it is the methyl donor in hundreds of biologic transmethylation reactions and the donor of propylamine in polyamine synthesis. Web6 apr. 2010 · Albumin has a long historical involvement in design of media for the successful culture of mammalian cells, in both the research and commercial fields. The potential application of albumins, bovine or human serum albumin, for cell culture is a by-product of the physico-chemical, biochemical and cell-specific properties of the molecule.
