食用油换成它，真的很不一样！减少脂肪堆积，有益血脂！缺点是…

甘油三酯（TAG）和甘油二酯（1,3-DAG）被胰蛋白酶分解后产物不一样，因此后续代谢也不一样。

分解产物不一样跟脂肪酸连接位置不一样有关，甘油三酯是甘油上的3个位置都连接了脂肪酸，我们把这3个位置编号成①、②、③

当甘油三酯到达小肠，会在胰脂肪酶作用下被拆掉外侧①、③位置的脂肪酸，剩下中间②位置的脂肪酸还连接在甘油上，这个东西叫2-MAG，它会被我们体内的两种酶（DGAT、MGAT）识别，快速重新合成为甘油三酯乳糜微粒，大部分用于储存，小部分用于供能。

受推崇的1,3-甘油二酯（1,3-DAG），是①、③两个位置连接了脂肪酸（1,3-DAG），而②位置空着的情况。

1,3-甘油二酯到了小肠，被拆掉靠外的其中一个脂肪酸后，剩下的是1-MAG。这个东西无法被酶识别，无法重新合成甘油三酯乳糜微粒用于储存，而分解出游离脂肪酸，送到肝脏进行β-氧化后直接供能。

肥胖方面

可能降低食物吸油量
