Milk is a complex biological fluid containing lipids, proteins, carbohydrates and minerals, which are essential for infant growth. While the lipid portion constitutes only 3%-5% of the total milk composition, it accounts for over 50% of the infant's daily energy intake. The dominant portion (approximately 98%) is in the form of triacylglycerols and polar lipids, such as glycerophospholipids and sphingolipids, forming minor components. Recently, with the development of lipidomics, important progresses have been made in milk lipidomics, and the identification and quantification of several milk lipids at the group and molecular species level has become a reality, thereby providing useful information for the infant formula industry. In this review, an overview of the separation of the main components of milk lipids was presented, including glycerolipids, phospholipids and sphingolipids. The analytical methods and strategies for milk lipidomics, including gas chromatography-mass spectrometry (MS), capillary electrophoresis MS, nuclear magnetic resonance, matrix-assisted laser desorption ionization-MS, electrospray ionization-MS, shotgun lipidomics and liquid chromatography-MS, were reviewed. Additionally, the bioinformatics of lipidomics for milk lipid determination, including lipid classification, lipid databases and lipid analysis software, were investigated. This review would aid future investigations of the nutrition of milk lipids and refined researches on formula milk powder. 相似文献

采用傅里叶变换红外光谱法对驴初乳、驴常乳、牛初乳和牛常乳的乳清蛋白二级结构进行分析,再通过基因本体论功能注释和KEGG(Kyoto Encyclopedia of Genes and Genomes)代谢通路分析其功能及差异。结果表明:驴乳和牛乳乳清蛋白的二级结构存在差异;随着泌乳期的延长,二者的乳清蛋白二级结构含量也会发生一定的变化;驴乳较牛乳参与的生物学功能和代谢通路更为丰富,且驴常乳作用最为明显,更有益于婴幼儿配方乳粉的开发与利用。 相似文献
