Antimicrobial Peptides Derived from Milk: A Review
Milk proteins provide a natural source of bioactive peptides with potential health benefits and applications in the food industry. The release of these peptides from milk proteins is achieved either by hydrolysis using digestive proteases or by lactic acid bacteria fermentation. Peptides, particularly those derived from milk proteins, can exert a wide range of nutritional, functional and biolog...
متن کاملEndothelial and lipoprotein lipases in human and mouse placenta.
Placenta expresses various lipase activities. However, a detailed characterization of the involved genes and proteins is lacking. In this study, we compared the expression of endothelial lipase (EL) and LPL in human term placenta. When placental protein extracts were separated by heparin-Sepharose affinity chromatography, the EL protein eluted as a single peak without detectable phospholipid or...
متن کاملLipoprotein and hormone-sensitive lipases in porcine adipose tissue.
Lipoprotein lipase (LPL) is an adipocyte enzyme that cleaves fatty acids from circulating lipoproteins. Fatty acids enter the cell to be oxidized or esterified. Hormone-sensitive lipase (HSL) is an adipocyte enzyme that cleaves fatty acids from intracellular triacylglycerol. The HSL is activated by phosphorylation. Assays for the two lipases are complex because the hydrophobic substrate, triacy...
متن کاملHepatic and lipoprotein lipases selectively assayed in postheparin plasma.
Sensitive, reliable procedures are reported for the selective assay of lipoprotein lipase (LPL) and hepatic lipase (HL) in postheparin plasma samples. LPL is inhibited in the HL assay by inclusion of 0.76 mol/L sodium chloride in the substrate. In the LPL assay, specificity is attained by pretreating the sample with sodium dodecyl sulfate, which selectively denatures HL. This LPL method was val...
متن کاملAction of Lipases of Staphylococcus Aureus on Milk Fat.
The activity of the lipase(s) of two strains of coagulase-positive Staphylococcus aureus was determined in milk fat incubated at 15, 22, and 30 C for 8 days. Total fat hydrolysis was measured by acid degree values (ADV). Neutral lipids were separated into component groups on a Florisil column. Free fatty acids were determined by temperature-programmed gas-liquid chromatography. The ADV were 25 ...
