The Composition and Biosynthesis of Milk Lipids.
A p a r t from the obvious importance of milk as the natural food of the infant mammal and, in the case of cows’ milk, as food for man, its ready availability has invited chemical and biochemical study. In respect of milk fat in particular, its special place in the history of lipid chemistry is noteworthy; it was included by Chevreul in his classical studies of 150 years ago (l), from which he ...
متن کاملMajor advances associated with the biosynthesis of milk.
The mammary gland has an incredible level of organization and a remarkable ability to convert circulating nutrients into milk components. This review highlights four areas of high interest in the biology of milk synthesis where advances over the last quarter-century have resulted in new understanding or revealed new opportunities. First, advances in our understanding of the mechanisms of milk s...
متن کاملBiosynthesis of Fucosyllactose and Other Oligosaccharides Found in Milk.
The carbohydrate fraction of human milk includes a number of chemically defined oligosaccharides which contain the 6-deoxyhexose, L-fucose (2, 3). The present report describes a particulate enzyme from lactating canine mammary tissue’ which catalyzes the synthesis of fucosyllactose,2 the simplest member of this group, by transfer of L-fucose from guanosine diphosphate L-fucose to lactose. If fu...
متن کاملBiochemical characterization and biosynthesis of the uterine milk proteins of the pregnant sheep uterus.
The uterine milk proteins (UTM-proteins), a pair of basic glycoproteins with similar isoelectric points and molecular weights (57,000 and 55,000), are secreted by the endometrium of the pregnant ewe. Peptide mapping of the two species of UTM-proteins demonstrated them to be structurally related. Furthermore, pulse-chase and continuous-labeling experiments indicated that both are produced from a...
متن کاملBiosynthesis of milk fat, protein, and lactose: roles of transcriptional and posttranscriptional regulation.
The demand for high-quality milk is increasing worldwide. The efficiency of milk synthesis can be improved by taking advantage of the accumulated knowledge of the transcriptional and posttranscriptional regulation of genes coding for proteins involved in the synthesis of fat, protein, and lactose in the mammary gland. Research in this area is relatively new, but data accumulated in the last 10 ...
