Abstract:
... A ferric oxyhydroxide nanoparticle (FeONP)-mediated mechanism has been suggested recently for anchovy (Engraulis japonicus) meat (AM) enhancement of non-heme iron absorption. The current paper fractionates AM biomass into protein (70.67%), lipid (20.98%), and carbohydrate (i.e., glycogen and mucopolysaccharide, 1.07%) and evaluates their capacities in templating the formation of FeONPs under simul ...

Abstract:
... Protein-tannin interactions on a molecular level were investigated by using a model system containing peptides of α-lactalbumin and berry tannins (procyanidins). Oxidation of isolated tryptic peptide LDQWLCEK (m/z 1034) with procyanidin B2 or procyanidin fraction (PF) isolated from aronia juice was monitored by LC-ESI-MS. Procyanidin B2 and PF showed radical scavenging activities toward oxidation ...
