[#Human breast milk] - The most abundant #Gangliosides in human milk are monosialoganglioside-3 (GM-3) and disialoganglioside-3 (GD-3). - GD-3 is very abundant in colostrum, while GM-3 increases in abundance at later time points [#Human breast milk] - #Phosphatidylcholine, phosphatidylethanolamine, and #Sphingomyelin contribute up to 40% of all MFGM #Phospholipids, which are subject to intra-individual variation, especially during early lactation [#Sphingomyelin] [#Human breast milk] -The outer MFG membrane also contains most of the sphingomyelins, for which many bactericidal activities against human opportunistic pathogens are described. [#Human breast milk, #Infants] - HMLs also include several compounds that are essential for infant development. For example, phosphorylated lipids, glycosylated lipids, short- and long-chain fatty acids, polyunsaturated fatty acids[8], and several fat-soluble vitaminsReferences Notes[ ]
