Calcium Binding of Phosphopeptides Derived from Hydrolysis of a s-Casein or ß-Casein Using Immobilized Trypsin
casein immobilized trypsin casein phosphopeptide calcium binding
2008/3/28
Calcium binding to casein phosphopeptides that were derived from s-CN or ß-CN was studied. Purified s-CN or ß-CN was prepared from fresh skim milk using an anion-exchange column. Peptides ...
Effects of Hydrolysis of Milk Glycerides on the Antimutagenicity of a Hexane Extract of Milk
hydrolysis milk glycerides antimutagenicity hexane extract
2008/3/28
Reconstituted nonfat dry milk was treated with different amounts of lipase from Pseudomonas fluorescens. Hexane extracts of treated milks were dissolved in dimethylsulfoxide and assayed for antimutage...
Differences in the Hydrolysis of Lactose and Other Substrates by ß-D-Galactosidase from Kluyveromyces lactis
ß beta -D-galactosidase metal effects substrate specificity
2008/3/27
The hydrolysis of o-nitrophenyl galactopyranoside and lactose by ß-D-galactosidase from Kluyveromyces lactis was enhanced by the addition of Mg2+ and Mn2+, but the rates of activation by each me...
The proteolytic activity of plasmin on soluble caprine ßcasein (CN) was studied in 50 mM Tris-HC1 buffer, pH 8.0, at 37°C. Electrophoretic studies showed that hydrolysis of this protein results ...
Hydrolysis Characteristics of Bovine Milk Fat and Monoacid Triglycerides Mediated by Pregastric Lipase from Goats and Kids
caprine pregastric lipase milk fat tributyrylglycerol monoacid triglycerides
2008/3/27
Commercial extracts from oro-pharyngeal tissues of goats and kids have been used as the source of pregastric lipase and have been processed to yield partially purified samples of the primary pregastri...
Characteristics of Tributyroylglycerol Hydrolysis Mediated by Partially Purified Lamb Pregastric Lipase
lamb pregastric lipase hydrolysis tributyroylglycerol
2008/3/25
A partially purified pregastric lipase from lambs was used as a catalyst for the hydrolysis of tributyroylglycerol. The reaction was followed by pH-stat autotitration of the released butyric acid. Int...

Consumption of fermented dairy foods has been linked to reduced incidence of colon cancer in population groups. Recently, biologically active compounds have been isolated from these products. Bacteria...
Calf and Lamb Lingual Lipases as Catalysts for the Hydrolysis of Tributyrin, Triolein, and 4-Nitrophenylacetate
calf lamb lingual lipase catalyzed hydrolysis
2008/3/19
The lingual lipases from calf and lamb were used as catalysts for the hydrolysis of the lipid, tributyrin, and the relatively hydrophilic ester, 4-nitrophenylacetate. The effects of pH on these reacti...
