这个激酶从自我磷酸的组氨酸上转移磷酸基，因此（为什么是这样）通常是可逆的，这个激酶也作为一个去磷酸酶。

The kinase transfers the phosphate from an autophosphorylated histidine and thus (why thus?) is often reversible, with the kinase acting as a phosphatase as well.

此外，其他阻止磷酸二酯酶活性的化合物不是兴奋剂。

Moreover, other compounds that block phosphodiesterase's activity are not stimulants.

但 Snyder 等人指出，抑制脑内磷酸二酯酶产生所需的咖啡因浓度要比产生刺激的咖啡因浓度高得多。

But Snyder et al point out that the caffeine concentrations needed to inhibit the production of phosphodiesterase in the brain are much higher than those that produce stimulation.

Often it's a salt called phosphocholine and so you get a phospholipid that's made of choline and two lipid chains.

它通常是一种叫磷酸胆碱的盐,这样你就得到了一种,由胆碱和两条脂肪链构成的磷脂
