Identification of Protein Fractions of Milk Cows Casein Complex.
To date, dozens of biologically active peptides formed during proteolysis of casein fractions have been discovered. The use of these peptides is closely related to the necessity of their rapid identification. The aim of this work was the development of an electrophoresis system for rapid identification of individual fractions in serial studies and the separation of the milk casein complex. Cons...
متن کاملDetermination of fat, protein, casein, total solids, and somatic cell count in goat's milk by near-infrared reflectance spectroscopy.
Analysis using near-infrared reflectance spectroscopy (NIRS) was investigated as a means of predicting quality parameters of goat's milk. Calibration equations were developed with samples from individual goats of Malagueña and Murciano-Granadina dairy breeds at different stages of lactation to obtain a wide range of variation in milk composition. Prediction equations for milk fat, protein, case...
متن کاملStability of casein micelles in milk
Casein micelles in milk are proteinaceous colloidal particles and are essential for the production of flocculated and gelled products such as yogurt, cheese, and ice-cream. The colloidal stability of casein micelles is described here by a calculation of the pair potential, containing the essential contributions of brush repulsion, electrostatic repulsion, and van der Waals attraction. The param...
متن کاملPurification of Golgi casein kinase from bovine milk.
Caseins and many other secretory proteins are phosphorylated during their transport through the secretory pathway by a protein kinase present within Golgi compartments. Molecular analysis of the Golgi casein kinase (GCK) has not been possible since it has not been purified to homogeneity or been cloned. Previous attempts have been made to purify GCK activity from mammary gland Golgi fractions, ...
متن کاملDetecting β-Casein Variation in Bovine Milk.
In bovine species, β-casein (β-CN) is characterized by genetic polymorphism. The two most common protein variants are β-CN A² (the original one) and A¹, differing from A² for one amino acid substitution (Pro67 to His67). Several bioactive peptides affecting milk nutritional properties can originate from β-CN. Among them, β-casomorphin-7 (BCM7) ranging from amino acid 60 to 66 can be released mo...
