Abstract:
In this paper, the effects of different proteins (soybean protein isolate, wheat protein hydrolysate, tremella protein) on the activity of tremella polysaccharide under different conditions were studied. The optimal protein–polysaccharide complex was determined by grafting degree and activity screening, and the microstructure and rheological properties were studied. The results showed that when the ratio of soybean protein isolate to tremella polysaccharide was 2:1 and the solution pH was 7, the optimal complex was obtained by heating at 90 °C for 4 h, and its grafting degree and antioxidant a

Hence, we have selected bovine serum albumin (BSA) having higher molecular weight (66.3 kDa) as a model protein and dextran sulphate (DS) as a complexing polymer to generate HIP complex. We have prepared and optimized the HIP complex formation process of BSA with DS. Ionic interactions between basic amino acids of BSA wit

The expression of polysaccharide capsules is common in bacteria and associated with virulence in some pathogenic strains. Strains of the Gram-negative bacterium Escherichia coli express a structurally diverse range of capsular polysaccharides. E. coli strains expressing group 2 capsules are associated with a number of extra-intestinal infections, including sepsis, urinary tract infections, and neonatal meningitis. Group 2 capsular polysaccharides are synthesised on the cytoplasmic face of the inner membrane. Evidence from previous work suggests that export of polysaccharides across the Gram-ne

Mixed solutions of β-lactoglobulin and anionic polysaccharides, specifically pectin, were formed into associative complexes through pH reduction from neutral conditions. Thermal treatment of these associative complexes was investigated as a function of biopolymer composition, heating conditions, pH, and ionic strength. Thermal treatment of β-lactoglobulin-pectin complexes at pH 4.5–5.0 was found to create protein-based particulates of consistent and narrow size distribution (diameter ∼ 150–400 nm). These particulates were relatively stable to further pH adjustment and to high levels of salt (2

Three different polysaccharides are considered: dextran, dextran sulphate, and amylopectin. A simple 1:3 mixture of protein+ dextran sulphate (0.5 wt% BSA, 10 wt% n-hexadecane) gives much better stability than with protein alone under similar conditions. Surface shear viscosity measurements are consistent with the presence of an electrostatic complex of BSA+ dextran sulphate adsorbed at the oil-water interface. Poor stab

To increase the immunogenicity, the capsular polysaccharide can be covalently linked to a protein carrier that converts carbohydrate antigen from T lymphocyte independent to T lymphocyte dependent ant

Thrombomodulin (TM) is an endothelial cell membrane protein chat acts as a cofactor for Protein C (PC) activation by thrombin (T). Rabbit TM also prevents fibrinogen clotting by T (direct anticoagulant activity) and accelerates T inhibition by antithrombin (AT-dependent anticoagulant activity). Rabbit TM was previously found to contain an acidic domain (presumably a heparin-like polysaccharide), separated from the PC cofactor site but required for the direct and AT-dependent anticoagulant activities. Although binding of TM to T modifies the specificity of T, it does not involve a modification

Proteins are widely used as emulsifiers in food formulations. However, emulsifying properties of proteins are weak at pH values close to their isoelectric point resulting in destabilization.

In this work, two different polysaccharides (pectin and gum Arabic) with a range of surface charges were chosen to investigate their interactions with pea proteins.
