1. Slices of lactating guinea-pig mammary gland were incubated with radioactive amino acids and the various subcellular fractions separated by centrifugation after disruption of the cells by mincing and homogenization. The most active fraction for protein synthesis appeared to be the ;mitochondrial'. 2. When the subcellular fractions were prepared without previous incubation of the cells and we...
Our previous study revealed that newborns had a high level of absorption of human milk a-lactalbumin. [1] It decreased during the first month in the whole and nonallergic infants showed a 4fold reduction of gut permeability at 25-30 days of life. But patients with early allergic symptoms have increased gut permeability in comparison to non-allergic infants. In this study we examined gut permeab...
Lyophilization stabilizes the biological materials by using two overlapping drying procedure i.e. primary drying by sublimation of the ice crystal from frozen material and secondary drying or desorption by evaporation of the free water adsorbed into the dried product. Three different stabilizers i.e. lactalbumin hydrolysate-sucrose, Weybridge medium and lactalbumin hydrolysate-manitol were used...
Introduction & Objective: Ficin is a member of plant cystein proteases that is abundant in fig. This enzyme has many pharmacological and industrial uses. In the present study, the enzyme was purified by a simple procedure and its proteolytic activity was assayed on several plant and animal proteins. Materials & Methods: Ficin was extracted from unripe fig, precipitated by ammonium sulfate and...
Thermal denaturation of a-Lactalbumin in the absence and presence of various concentrations of sucrose,sorbitol, glucose and galactose as sugar osmolytes were measured by monitoring changes in the absorptions thatcarried out in a Lambd 35 UV-Vis double beam spectrophotometer at pH 6.0. These measurements gave valuesof T., (midpoint of denaturation), AH., (enthalpy change at T.), and ACp (consta...
From the effects of N-acetyl-d-glucosamine and d-glucose on the elution of the A protein of human lactose synthetase from a column of Sepharose-alpha-lactalbumin, values of 200m(-1) and 0.57m(-1) are deduced for the association constants describing the interaction between the enzyme and the respective monosaccharides.
A double lumen jejunal perfusion technique has been used in man to study the effect of peptide chain length on absorption of amino acid nitrogen from two partial enzymic hydrolysates of lactalbumin. Copper-chelation chromatography showed that one lactalbumin hydrolysate (LH2) contained 98% peptides with a chain length greater than 4, whilst the other (LH1) contained a more even spread of chain ...
Macromolecular absorption of gliadin, a wheat protein and alpha lactalbumin, a milk protein was evaluated in control and Escherichia coli enterotoxin (heat-stable, heat-labile, and both heat-stable and heat-labile enterotoxin) treated mice. The peak concentration of gliadin and lactalbumin was two hours and three hours after their ingestion, respectively. There was also a significant increase (...
