摘要：

Human milk is a natural source of medium-chain fatty acids (MCFAs). It is generally acknowledged that MCFAs exist in medium-chain triacylglycerols (MCTs). However, a previous study revealed that human milk is naturally rich in medium- and long-chain triacylglycerols (MLCTs). Few data are available on the MLCT composition of preterm milk. This study compared the MCFA and MLCT profiles in human milk from mothers after preterm (28-37 weeks) and term (>37 weeks) delivery during three lactational stages. The results showed that almost half of the triacylglycerol species in human milk are MLCT, accounting for approximately 30% of the total TAGs, mainly composed of one MCFA and two long-chain fatty acids, that is, MLL-type MLCT. In addition, MCFAs and MLCTs showed an increase from colostrum to transitional milk, while they were comparable between preterm and full-term milk. This research could help to develop infant formula, which is of great significance for infants.
