Activity of L-gulonolactone oxidase (EC 1.1.3.8) in livers of fetal Rattus norvegicus and Mus musculus was detectable on the 18th day of gestation, increased rapidly to maxima at 15 and 5 days postpartum for the two species, respectively, and thereaf

This report reviews changes the nomenclature of bovine milk proteins necessitated by recent advances of our knowledge. Identification of a number of milk proteins ( α s1 -, β -, and κ -caseins; α -lactalbumin and β -lactoglobulin) continues to b

Research in the past decade has extended knowledge of composition of goat milk and of properties of its constituents. Goats of several European breeds produce milk of lower fat content in the tropics than in temperate zones. Fat, protein, and lactose

1. 1. The activity of l -gulonolactone oxidase (EC 1.1.3.8) in the liver of eastern cottontail rabbits ( Sylvilagus floridanus ) is about 10-fold greater in winter than in summer. 2. 2. l -gulonolactone oxidase activity is low and tissue ascorbate hi

1. 1. Milk specimens from 5 wild and 2 captive sea otters, Enhydra lutris , were analyzed for pH, gross composition and calcium, phosphate and citrate. Osmolality of two samples was determined. 2. 2. The pH is lower and osmolality higher than in milk

κ -Casein-like proteins were isolated from the milks of cow, goat, reindeer, horse, rat, and rabbit. When treated with rennin, all of the isolated κ -casein components yielded para- κ -casein-like bands on gel electrophoresis. The rate of cleavage

Whole rat casein, precipitated from milk at pH 4.0, was resolved into three major fractions on diethylaminoethyl-cellulose at pH 7 in the presence of urea and mercaptoethanol. Each fraction, upon further analysis, appeared to consist of at least two

Some of the constituents of milk are unbiquitous biochemical compounds and others are unique products of the mammary gland. Lactose, the distinctive milk disaccharide, caseins, a group of phosphoproteins, and fat are present in nearly all milks that

1. 1. A 315cm lactating female pygmy sperm whale, Kogia breviceps , accompanied by a 156cm female calf stranded on south Miami Beach, Dade County, Florida, on 13 March 1974, were used in the experiment. 2. 2. A sample of milk from the lactating femal

1. 1. The activity of l -gulonolactone oxidase (EC 1.1.3.8) in livers of 49 species of eutherian mammals varied intraspecifically among individuals; coefficients of variation were 0.2 to 0.4 in many species. 2. 2. Differences observed in l -gulonolac
