环型腺苷酸(cAMP),几乎存在于机体内的每个细胞,它是由激素(机体的第一化学信使)将生物化学信息传递给细胞膜上的受体,使膜上的腺苷酸环化酶(AC)活化,从而催化细胞内的三磷酸腺苷(ATP)转变成cAMP。cAMP则直接控制或调节细胞内的新陈代谢、离子通透性以及许多生理功能,它被称为机体的“第二化学信使”。而环式腺苷酸磷酸二脂酶(cAMP-PDE),则是催化cAMP分解的酶,凡有cAMP存 Cyclic adenine (cAMP), which is found in almost every cell in the body, transmits biochemical information to the receptors on the cell membrane by the hormone (the first chemical messenger of the body) Cyclase (AC) is activated to catalyze the conversion of intracellular adenosine triphosphate (ATP) to cAMP. cAMP directly controls or regulates intracellular metabolism, ion permeability, and many physiological functions. It is called the “second chemical messenger” of the body. The cyclic adenylate phosphodiesterase (cAMP-PDE), is the catalytic cAMP decomposition of the enzyme, where cAMP deposit
