Using stool samples previously obtained for a nutritional balance study of very small infants, the intake, excretion, and percent absorption (%A) of individual fatty acids were quantitated by gas-liquid chromatography in two groups of patients; one receiving a formula providing fat as long chain triglycerides (LCT), the other providing 40% fat as medium chain triglyceride (MCT). The total fat intake for each group was 7.22 g/kg/day (MCT group), 6.02 g/kg/day (LCT group) and the absorption was 6.79 g/kg/day (MCT group) and 5.41 g/kg/day (LCT group). The %A of individual acids was comparable in both groups being greater than 99% for MCT and being lowest (62%) for C18:0 FA. As a consequence, infants in the MCT-fed group had a better total %A of fat, 95.2 vs 89.9% and absorbed more fat than the LCT group.
利用先前为极小型婴儿营养平衡研究采集的粪便样本，通过气液色谱法对两组患者个体脂肪酸的摄入量、排泄量和吸收百分比（%A）进行了定量分析；一组接受以长链甘油三酯（LCT）形式提供脂肪的配方奶，另一组接受40%脂肪为中链甘油三酯（MCT）的配方奶。每组的总脂肪摄入量分别为7.22克/千克/天（MCT组）、6.02克/千克/天（LCT组），吸收量分别为6.79克/千克/天（MCT组）和5.41克/千克/天（LCT组）。两组中各脂肪酸的%A相当，MCT组大于99%，C18:0脂肪酸最低（62%）。因此，喂食MCT组的婴儿脂肪总%A更高，为95.2%，而LCT组为89.9%，且MCT组婴儿比LCT组吸收更多脂肪。
