The biological membrane surrounding milk fat globules (MFGM) exhibits lateral phase separation of lipids, interpreted as gel or liquid-ordered phase sphingomyelin-rich (milk SM) domains dispersed in a fluid continuous lipid phase. The objective of th

Sphingomyelin (SM) molecules are major lipid components of plasma membranes that are involved in functional domains. Among natural SMs, that found in milk (milk-SM) exhibits important acyl chain heterogeneities in terms of length and saturation, whic

The microstructure of the milk fat globule membrane (MFGM) is still poorly understood. The aim of this study was to investigate the dynamics of the MFGM at the surface of milk fat globules in relation to temperature and time, and in relation to the r

The milk sphingomyelin (MSM) is involved in the formation of ordered lipid domains in the biological milk fat globule membrane (MFGM), where it accounts for about 30%wt of the polar lipids. Moreover, MSM exhibits a large variety in saturated acyl cha
