Fourteen samples of milk fat, representing a wide range of individual fatty acid contents, were subjected to stereospecific analysis to determine fatty acid contents at the sn-1-, sn-2- and sn-3-positions of the triglycerides. Highly significant linear relationships were found between the content of a fatty acid at the 3 positions and the content of the same acid in the intact triglycerides. As the content of an acid increased in the triglycerides there were increases in the content of that acid at the 3 positions. When the content of an acid changed in the triglycerides, the content at the 3 stereospecific positions did not change at the same rate. The positions with the highest slope values corresponded to the positions where the individual fatty acids were preferentially esterified.
选取了14个乳脂肪样本，这些样本的个体脂肪酸含量范围广泛，对其进行立体专一性分析，以确定甘油三酯sn-1-、sn-2-和sn-3-位的脂肪酸含量。结果发现，某一脂肪酸在这3个位置的含量与完整甘油三酯中该酸的含量之间存在高度显著的线性关系。随着甘油三酯中某一酸含量的增加，该酸在这3个位置的含量也会增加。当甘油三酯中某一酸的含量发生变化时，其在3个立体专一性位置的含量变化速率并不相同。斜率值最高的位置对应于各个脂肪酸优先酯化的位置。
