Introduction to Part I: Caged Neurotransmitters

The field of organic chemistry has provided neurobiologists with the ability to release biologically active neurotransmitters at precise locations and times of their choosing. These molecules are silent before the active molecule is released

Are Caged Compounds Still Useful

Since much of the life of cells is controlled by their chemistry, caged compounds can be used to intervene in this life in a myriad of specific ways. Organic chemists have synthesized the widest possible array of caged compounds for use

S－腺苷甲硫氨酸 S－adenosylmethionine

　　S－腺苷甲硫氨酸 S－ adenosylmethionine 亦称活性甲硫氨酸，在生物体内由 ATP与甲硫氨酸在甲硫氨酸活化酶的作用下合成。甲硫键是高能键，另外其丙基胺部分也加入到多胺化合物中。当胆碱、肌酸及其它甲基化合物生成时它作为甲基供体而起作用。认为甲硫氨酸的分解也经过此物质。
