Monospecific antisera were produced to two chylomicron apoproteins (apoB, apoA-I) and utilized for indirect immunofluorescent localization of these apoproteins within rat intestinal epithelium during normal and impaired lipid absorption. Isolated intestinal epithelial cells prepared after different periods of lipid absorption from in situ intestinal segments revealed a rapid increase in fluores...

Fish protein hydrolysates were prepared from Cuttlefish (Sepia pharaonis) muscle using alcalase and protamex methods. By conducting the Cuttlefish protein hydrolysate using alcalase (CPHA), it showed higher degrees of hydrolysis, proximate composition, yield, emulsifying activity index (EAI), emulsion stability index (ESI), foaming activity index (FAI), solubility, water holding capacity (WHC) ...

Peptide and protein drugs have found an important position in therapeutics. Recent advances in pharmaceutical biotechnology have led to an increase in the number of protein products in the market. As these therapeutic proteins and peptides are made available, it will be essential to formulate these drugs into safe and effective delivery systems. The twenty different naturally occurring amin...

BACKGROUND Roux-en-Y gastric bypass (RYGB) restricts food intake, and when the Roux limb is elongated to 150 cm, the procedure is believed to induce malabsorption. OBJECTIVE Our objective was to measure total reduction in intestinal absorption of combustible energy after RYGB and the extent to which this was due to restriction of food intake or malabsorption of ingested macronutrients. DESI...

Previous studies showed better absorption of protein and catch-up growth with animal-based high protein (15% energy from protein) diets (AP) than plant-based diets. This study compared the intake and absorption of nutrients from a lentil-based high protein (15% energy from protein) diet (LenP), AP, and a low protein (7.5% energy from protein) diet (LP). A total of 31 moderately malnourished 24 ...

We investigate the thermal denaturation of human serum albumin and the associated solvation using terahertz (THz) spectroscopy in aqueous buffer solution. Far- and near-ultraviolet circular dichroism spectroscopy reveal that the protein undergoes a native (N) to extended (E) state transition at temperature ≤55°C with a marginal change in the secondary and tertiary structure. At 70°C, the protei...

abstractinteraction of ni complex(salen= n, n´-ethylene bis(salicylideneimine)) with hen egg-white lysozyme (hewl) was studied by absorption spectroscopy, competitive binding study and thermal denaturation study. the protein binding affinity of ni complex was found to be (3.0×103m−1). the binding plot obtained from the absorption titration data gives a binding constant of 2.4 (± 0.3)×103 m-1. i...
