文摘
Two new natural amino acids, (Rs)-3-[(methylthio)methylsulfinyl]-l-alanine and S-[(methylthio)methyl]-l-cysteine, were isolated from the fruit of Scorodocarpus borneensis which is known to have a garlic-like odour. C–S lyase-mediated enzymatic conversion showed that both amino acids play an important role in developing the main odorous components of methyl methylthiomethyl disulfide and bis(methylthiomethyl) disulfide.
