1.SIRT1 depends on a molecule called NAD (Nicotinamide adenine dinucleotide), and NAD, in turn, depends on the substance called NMN.

SIRT1合成取决于种叫NAD（辅）子，而NAD合成则取决于种叫NMN物质。

2.In the first stage, the energized electrons from chlorophyll are used to create two vital energy--carrying molecules: ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate).

在第阶，叶绿素激发电子被用产生两种携带生命能量子：ATP（三磷酸腺苷）和NADPH（烟酰胺腺嘌呤二核苷酸磷酸）。机翻
