Acceleration of fibrin polymerization by calcium ions.
T HE FINAL STEPS OF THE CLOTTING PROCESS, in which fibrinogen (Factor I) is transformed to fibrin through the action of thrombin, is customanily described as taking place in three stages. Initially, thrombin, a proteolytic enzyme of high substrate specificity, cleaves four arginyl-glycine bonds in each fibrinogen molecule, so that two pairs of peptide fragments are released. During the second s...
متن کاملAlphas1-casein, milk composition and coagulation properties of goat milk
Amounts of alphas1-casein (as1-CN), protein, fat, SNF and total solids were measured in 125 goat milk samples. Coagulation time, coagulation rate and curd ®rmness were measured in 75 goat milk samples by dynamic mechanical analysis using a Bohlin VOR Rheometer. After adjustments were made for month, time of milk collection and animal age, it was con®rmed that goat milk with high percent total s...
متن کاملInfluence of bovine and caprine casein phosphopeptides differing in alphas1-casein content in determining the absorption of calcium from bovine and caprine calcium-fortified milks in rats.
Bovine and caprine milks have a similar overall gross composition, but vary considerably in the ratios of their casein components. These differences cause significant changes in the ability of caseins to bind and stabilize calcium (Ca). It might be expected that these in vitro variations, which are thought to be due to differences in casein phosphopeptides (CPP) content, could lead to in vivo d...
متن کاملKappa-casein gene polymorphism in Indian goats
The present work was carried out to analyse the κ-casein variants in five Indian goat breeds by SDS-PAGE, PCRRFLP and SSCP method. A total of 152 unrelated blood samples and 102 milk samples belonging to Barbari, Beetal, Marwari, Surti and Local MP (non-descript) goats were used for analysis. SDS-PAGE exhibited κ-casein allele A in all the breeds. Moreover PCR+RFLP analysis also confirmed the p...
متن کاملPolymorphism of alphas1-casein gene in a dairy goat herd in the southeastern region of Brazil1
Three different regions of the alphas1-casein gene (CSN1S1) were investigated to determine the frequencies of major alleles for null, low, intermediate and high milk protein expression in a herd of dairy goats raised in the southeastern region of Brazil. Genomic DNA samples were obtained from leukocytes of 145 dairy goats and regions of interest in the gene were amplified through Polymerase Cha...
