Bovine milk fat globule membrane proteome.
Milk fat globule membranes (MFGM) were isolated from the milk of mid-lactation Holstein cows. The purified MFGM were fractionated using 1-dimensional SDS gels. Tryptic peptides from gel slices were further fractionated on a micro-capillary high performance liquid chromatograph connected to a nanospray-tandem mass spectrometer. Analysis of the data resulted in 120 proteins being identified by tw...
متن کاملMilk Fat Globule Membrane Proteomics: A 'Snapshot' of Mammary Epithelial Cell Biology
Lipids are released in milk as fat globules, which are droplets of apolar lipids surrounded by a complex membrane deriving from the mammary epithelial cell (MEC) and called the milk fat globule membrane (MFGM). The structure of the MFGM is highly complex and closely related to the mechanisms of milk fat globule secretion in the mammary epithelial cell. Indeed, MFGM is composed of two biological...
متن کاملBiochemical and Morphological Comparison of Plasma Membrane and Milk Fat Globule Membrane from Bovine Mammary Gland
Purified plasma membrane fractions from lactating bovine mammary glands and membranes of milk fat globules from the same source were similar in distribution and fatty acid composition of phospholipids. The sphingomyelin content of the phospholipid fraction of both membranes was higher than in these fractions from other cell components, beta-carotene, a constituent characteristic of milk fat, wa...
متن کاملDietary milk fat globule membrane improves endurance capacity in mice.
Milk fat globule membrane (MFGM) comprises carbohydrates, membrane-specific proteins, glycoproteins, phospholipids, and sphingolipids. We evaluated the effects of MFGM consumption over a 12-wk period on endurance capacity and energy metabolism in BALB/c mice. Long-term MFGM intake combined with regular exercise improved endurance capacity, as evidenced by swimming time until fatigue, in a dose-...
متن کاملMilk Fat Content and DGAT1 Genotype Determine Lipid Composition of the Milk Fat Globule Membrane
During secretion of milk fat globules, triacylglycerol (TAG) droplets are enveloped by a phospholipid (PL) trilayer. Globule size has been found to be related to polar lipid composition and fat content, and milk fat content and fatty acid composition have been associated with the diacylglycerol acyltransferase 1 (DGAT1) K232A polymorphism; however, the association between the DGAT1 polymorphism...
