the objective of this study was to produce fish peptone from tuna (thunnus tonggol) viscera, by alcalase. response surface methodology (rsm) was employed for optimizing the temperature and ph. hydrolysis was done in different tempratures (50-65˚c) , ph (8-8. 5) and selected 13 treatments. samples with higher value of protein were used instead of the standard peptones which applied in commercial...

The interaction between felodipine and bovine serum protein was studied, the optimal experimental conditions were selected, fluorescence quenching mechanism discussed. filodipine determined by UV spectrophotometry, selected control variable method. of in system explored spectrophotometry. intensity most obvious under buffer solution pH 7.4, concentration 8.0*10 -4 mol/L, reaction time 30min 25°...

A technic, efficient in use ~ of I TM, has been developed for introducing I TM into 4-mg. amounts of antibody or 3,-globulin protein at a level of 10 me. I ~al per mg. protein with a resulting iodine content of ~-S atoms per protein molecule of 160,000 molecular weight. Oak Ridge I TM was adjusted to pH 8 with borate buffer and the requisite amount of hydrochloric acid. To this solution was add...

 The a im of th is paper was to study the effects w hey pro t e in c oat i ng on ch e m ic al a nd physic al properties of gut t ed K i l ka dur i ng f roz en stor a ge. Coating of Kilka has done by dipping in whey protein solution with different concentrations of 3, 7, 10 and 13%, for 1h. Then, after being packed in polyethylene dishes, they were covered in cellophane blanket and stored in -18...

ophthalmia neonatorum is generally defined as conjunctivitis occurring within one month of life. the sources of this infection are environmental organisms or the organisms colonized in the birth canal. untreated infection can cause blindness, especially if the corresponding organisms areneisseria gonorrhoeae, or chlamydia trachomatis. povidone-iodine ophthalmic solution is an effective antibact...

This study was conducted to investigate the effects of infrared processing of barley for 60, 90, 120 and 150 seconds (s) on protein hydrophobicity, in vitro protein digestibility, degradation characteristics of protein and starch and its feeding effect on ruminal pH of sheep. The surface hydrophobicity of protein increased (P

DivK is an essential response regulator in the Gram-negative bacterium Caulobacter crescentus and functions in a complex phosphorelay system that precisely controls the sequence of developmental events during the cell division cycle. Structure determinations of this single domain response regulator at different pH values demonstrated that the five-stranded alpha/beta fold of the DivK protein is...
