Microbial conversion of lactose to lactobionic acid (β-O-D-galactosyl D-gluconic acid) was carried out with the resting cells of a mutant strain of Burkholderia cepacia that showed tolerance to high l...
Why is Lactose a Dominant Saccharide in Milk?
evolution of lactose and milk oligosaccharides lactose milk oligosaccharides lactation α-lactalbumin
2008/4/19
Mammalian milks usually contain a few percent of carbohydrate. The milk of most of the Eutheria, with a few exceptions, contains lactose (Gal(β 1-4)Glc) as the dominant saccharide; lactose accounts fo...
