Observations on the Fat Globules in Milk

The Macrostructure of Milk Lipids: The Fat Globules.

The aim of this review article is to summarize the information available related to milk fat globules (MFGs) in order to highlight their contribution to the nutritional and technological characteristics of milk and dairy products. The macrostructure of milk lipids is composed of globules made up of triglycerides with different melting points, enveloped by a biological membrane from the mammary ...

Characterization of fat globules and milk fat globule membrane proteins in milk of different yak breeds

The objective of this work was to characterize the fat globule and milk fat globule membrane (MFGM) proteins in Maiwa (n = 6), Gannan (n = 4) and Zhongdian yak whole milks (n = 4). Fat globule size distribution and specific fat surface area of whole yak milk were determined using a laser diffraction particle size analyzer. The average specific fat surface area of Gannan yak milk (2.05 m·mg) and...

Electron Microscopic Localization of Cholesterol in Bovine Milk Fat Globules

Size-dependent lipid content in human milk fat globules.

Human milk fat globules (HMFGs) are considered to constitute a triglyceride-rich source of fat and energy. However, milk contains lipid particles at different sizes ranging from tens of micrometers to less than 1 microm. In particular, the physical, chemical, and biological properties of submicron sized particles are poorly described. Individual HMFGs were analyzed using laser trapping confocal...

Bovine milk fat globules do not inhibit C5a chemotactic activity.

The C5a complement fragment is a potent inflammatory molecule but its contribution to the inflammatory response of the mammary gland remains uncertain. One of the unresolved questions is the possible interference of whole milk with C5a. In this study, the chemotactic activity ofpurifled bovine C5a was tested in the presence of whole or skimmed milk. Milk from healthy glands acted as a chemoattr...
