|Section2= |Section3= }} Dimethylsulfoniopropionate (DMSP), is an organosulfur compound with the formula (CH3)2S+CH2CH2COO−. This zwitterionic metabolite can be found in marine phytoplankton, seaweeds, and some species of terrestrial and aquatic vascular plants. It functions as an osmolyte as well as several other physiological and environmental roles have also been identified. DMSP was first identified in the marine red alga ''Polysiphonia fastigiata'' by Frederick Challenger and Margaret Simpson (later Dr. Whitaker) 〔 〕 ==Biosynthesis== In higher plants, DMSP is biosynthesized from S-Methylmethionine. Two intermediates in this conversion are dimethylsulfoniumpropylamine and dimethylsulfoniumpropionaldehyde.〔Scott D. McNeil, Michael L. Nuccio, and Andrew D. Hanson "Betaines and Related Osmoprotectants. Targets for Metabolic Engineering of Stress Resistance" Plant Physiology, August 1999, Vol. 120, pp. 945–949. 〕 In algae, however, the biosynthesis starts with removal of the amino group from Methionine, rather than from S-Methylmethionine. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「dimethylsulfoniopropionate」の詳細全文を読む スポンサード リンク
