Metal-chelating peptides, which form metal–peptide coordination complexes with various metal ions, can be used as biofunctional ingredients notably to enhance human health and prevent diseases.
2,2’-(Ethylenedioxy)bis(ethylamine)-functionalized graphene quantum dots (GQDs) were prepared under mild conditions from oxide (GO) via oxidative fragmentation. The as-prepared GQDs have an average diameter of ca. 4 nm, possess good colloidal stability, and emit strong green-yellow light with a photoluminescence (PL) yield 22% upon excitation at 375 nm. We also demonstrated that the exhibit high photostability PL intensity is poorly affected while tuning pH 1 to 8. Finally, can be used...
Metal-Chelating Peptides (MCPs), obtained from protein hydrolysates, present various applications in the field of nutrition, pharmacy, cosmetic etc. The separation MCPs hydrolysates mixture is challenging, yet, techniques based on peptide-metal ion interactions such as Immobilized Metal Ion Affinity Chromatography (IMAC) seem to be efficient. However, processes are time consuming and expensive, therefore prediction using chromatography modelling simulation should necessary. Meanwhile,...
Various peptides can be obtained through protein enzymatic hydrolysis. Immobilized metal ion affinity chromatography (IMAC) is one of the methods which used to separate chelating (MCPs) in a hydrolysate mixture. In this context, work aims understand deeply interactions IMAC and surface plasmon resonance (SPR) order validate experimentally analogy between both technologies further able perform modeling next using peptide sorption isotherm parameters from SPR. Indeed, predict separation MCPs...
Novel protein chimeras constituted of "silk" and a silica-binding peptide (KSLSRHDHIHHH) were synthesized by genetic or chemical approaches their influence on silica-silk based chimera composite formation evaluated. Genetic constructed from 6 15 repeats the 32 amino acid consensus sequence Nephila clavipes spider silk ([SGRGGLGGQG AGAAAAAGGA GQGGYGGLGSQG]n) to which one silica binding was fused at N terminus. For chimera, 28 equiv chemically coupled natural Bombyx mori after modification...
β-Galactosidase (β-Gal) is one of the most important enzymes used in milk processing for improving their nutritional quality and digestibility. Herein, β-Gal has been entrapped into a meso-macroporous material (average pore size 9 200 nm, respectively) prepared by sol-gel method from silica precursor dispersion solid lipid nanoparticles micelle phase. The physisorption enzyme depends on concentration feed solution support. preferentially adsorbed either mesopores or macropores, depending its...
A novel approach consisting of preselection peptides using bioinformatics tool followed by final selection Surface Plasmon Resonance (SPR) - an efficient technique to investigate metal complexing properties peptides/hydrolysates was developed. Selected pea hydrolysates and synthetic chelating potentially present in were investigated for their ability inhibit the lipid oxidation emulsions composed 5 % w/w fish oil stabilized with Tween® 20. Results indicated that addition did not impact...
