Triacylglycerol (TAG) composition in 180 commercial infant, follow-on and growing-up formulas with different fat sources (plant oil, cow's milk and goat's milk) were analyzed and compared with mature human milk (MHM). TAGs in formulas were greatly affected by fat source. Formulas contained higher proportions of TAGs with short-chain/medium-chain saturated fatty acids, OOO and acyl carbon number (ACN) 54, and lower proportions of ACN 52 than MHM. There were significant differences in the content and stereochemical structure of OPL and OPO between formulas and MHM. Although there were no significant differences in the OPO contents between formulas with OPO and MHM, it is not enough to reach the abundance of palmitic acid (PA) at the sn-2 position in MHM. These results indicated that it is more suitable for Chinese infants to supplement the formulas with not only OPO, but also other TAGs containing PA mainly at the sn-2 position (such as OPL).
对 180 种不同脂肪来源（植物油、牛奶和羊奶）的婴儿配方奶粉、后续配方奶粉和成长配方奶粉进行了三酰甘油 (TAG) 组成分析，并与成熟母乳 (MHM) 进行了比较。配方中的 TAG 受脂肪来源的影响很大。配方中含有更多的短链/中链饱和脂肪酸、OOO 和酰基碳数 (ACN) 54 的 TAG，以及较少的 ACN 52 的 TAG，而 MHM 则含有更多的 ACN 52 的 TAG。配方和 MHM 之间的 OPL 和 OPO 的含量和立体化学结构存在显著差异。虽然 OPO 配方与 MHM 之间的 OPO 含量没有显著差异，但还不足以达到 MHM 中 sn-2 位棕榈酸 (PA) 的丰富程度。这些结果表明，对于中国婴儿来说，补充不仅含有 OPO，而且还含有其他主要在 sn-2 位含有 PA 的 TAG（如 OPL）的配方更为合适。
