说明

DL-蛋氨酸已用于研究单克隆抗体开发过程中蛋氨酸对氧化的敏感性。
蛋氨酸是一种必需的氨基酸,是转甲基化和转硫的前体。在蛋白质中,L-蛋氨酸是生物活性形式。D-蛋氨酸被体内的酶转化为L-蛋氨酸。蛋氨酸的腺苷基化导致S-腺苷-L-蛋氨酸(SAM)的形成,它作为各种物质的甲基供体。众所周知,L-蛋氨酸的代谢产物谷胱甘肽可调节免疫反应并具有抗病毒作用。

应用

DL-Methionine has been used to study the susceptibility of methionine to oxidation during the development of monoclonal antibodies.[1]
 

生化/生理作用

Methionine is an essential amino acid which acts a precursor for transmethylation and transsulfuration. In proteins, L-methionine is the biologically active form. D-methionine is converted to L-methionine by enzymes in the body.[2] The adenosylation of methionine results in the formation of S-adenosyl-L-methionine (SAM), which serves as a methyl donor to various substances. L-Methionine′s metabolic product glutathione is known to regulate immune response and has antiviral action.[3]
