时差N小时 脂肪是如何储存的?(上)（在线收听）

When you eat a fatty food, it moves through the stomach and on to the intestines.

当你食用富含高脂肪的食物时，它会通过胃进入肠道。

In the intestines, a number of processes occur to transfer fat from the food to special fat cells in your body.

在肠道中，脂肪经过一系列的消化过程后从食物中转化为体内的特殊脂肪细胞。

First, the gall bladder produces bile that breaks the food's fat droplets into smaller droplets.

首先，胆囊分泌胆汁，将食物中的脂肪滴分解，使其变得更小。

Next, the pancreas secretes enzymes that attack the fat droplets and break them down into two parts: fatty acids and glycerol.

然后，胰腺分泌的胰腺酶将脂肪滴分解为两个部分：脂肪酸和甘油。

This happens because fat droplets are too big to pass through cell membranes.

这是因为脂肪滴太大，无法穿透细胞膜。

The broken down fat is absorbed by the cells lining the intestine, where it is reassembled into fat molecules and eventually shuttled into the blood stream with the help of lipoprotein particles.

分解后的脂肪被肠道粘膜细胞吸收，并重新组成脂肪细胞，最后通过脂蛋白颗粒的帮助进入血液循环。
