In this study, protein and salt distributions in the milk of 48 Holstein-Friesian cows were studied. Gross composition samples variation between individual was line with expectation. However, mineralisation casein fraction, expressed mmol protein-associated calcium per 10 g casein, differed >2-fold samples. Reasons for are unknown could not be correlated to and/or genetic variants caseins. Furt...

Protein aggregation and precipitation is associated with many debilitating diseases including Alzheimer's, Parkinson's, and light-chain amyloidosis. β-Casein, a member of the casein family, has been demonstrated to exhibit chaperone-like activity to protect protein form aggregation. Hofmeister salts (lyotropice series) are a class of ions which have an effect on the solubility and also the stab...

Background: Genetic polymorphism of milk proteins has been associated with composition, manufacture, and traits of milk. Caseins are the most important milk proteins whose genes are strongly linked and inherited as a raceme. κ-casein which is a quantitatively minor constituent of bovine milk is thought to play a critical role in organization, fixation and aggregation of casein micelles and firm...

Protein aggregation is phenomenon wherein protein loses its native structure and aggregates due to the adaption of non-native conformation. Amyloid aggregation formed by the accumulation of various proteins causes many diseases in humans and other organisms. Antioxidants can prevent proteins aggregation. Pulicaria undulata  extract along with phenolic compounds can increase protein stability an...

The functionality of caseins in food systems depends on their solubility. The solubilities of whole casein, cr,l-casein, /3-casein, and dephosphorylated whole casein were measured as the pH was adjusted from 7 to 2 with HCl. When NaCl was added before pH adjustment, solubilities of whole casein at pH 2.5 decreased by 25, 40, 85, and 98% at NaCl concentrations of .01, .05, .1 and .2 M, respectiv...

The different types of P in modified caseins and the role of P in casein interactions were studied using 31P nuclear magnetic resonance spectroscopy of whole casein with reduced or elevated P concentrations and using Fourier transform infrared spectroscopy of whole casein with elevated P concentrations. Bovine whole casein (5.7 mmol of P/mmol of casein, 100% P) was either enzymatically dephosph...

The design and tests of slow-release formulations of sulfometuron (SFM), an anionic sulfonylurea herbicide, are described. The formulations are based on incorporation of the herbicide in octadecyltrimethylammonium (ODTMA) micelles, which adsorb on a clay mineral, montmorillonite. An optimization of herbicide/micelle clay ratios yielded high adsorption of SFM (95%), and at a 1% (w/w) water suspe...

three multiparoys lactating sannen dairy goats in midlactation with mean milk production and dim pf 1.5 ±0.22 kg and 167±4 days were used to determine effects of the abomasal infusion wheat starch, wheat starch or cottonseed oil with casein on performance of sannen dairy goats. goats were fed ad libitum with basal diet include, 40% hay alfalfa and 60% concentrate. treatments were abomasal infus...

Purpose: This paper focuses on the characterization of polymeric micelle-forming tuberculostatic prodrugs and the antimycobacterial activity of these prodrugs. Method: By the condensation of hydroxymethylpyrazinamide, isoniazid and rifampin with free carboxyl groups on the copolymer poly(ethyleneglycol)-poly(aspartic acid), micelle-forming carrier-drug conjugates were obtained. These micelles w...
