对DNA来说,这些单位是C、T、A和G碱基,对蛋白质来说这些单位是20个不同的氨基酸。
For DNA, these units are the c, t, a and G bases, and for proteins the units are 20 different amino acids.
一份含有:420卡路里,15.1克脂肪(5.4克单元不饱和脂肪酸、1.7克多元不饱和脂肪酸、6.4克饱和脂肪酸),235毫克胆固醇,53克碳水化合物,2克纤维素,17克蛋白质,693毫克钠

为了有效地战胜这类营养不良和营养不足,每人每天需要20克的动物蛋白或每年7.3公斤动物蛋白。
To effectively combat such malnutrition and under-nourishment, 20 g of animal protein per person per day or 7.3 kg per year should be provided.
When the ligand is present it binds to the receptor outside the cell and it activates this G-protein.
当配体存在并与细胞表面的受体结合时,就会激活G蛋白
It's called the G-protein coupled receptor because it's a receptor, like the one shown here, that's coupled to a special molecule called a G-protein.
之所以叫这个名字是因为这种受体,就像这里展示的一样,是与一种叫做G蛋白的特殊分子偶联的
The G-protein then goes on to create some other biochemical changes inside the cell.
然后G蛋白在细胞内,诱发其它的一些生化反应
