In plant-based food, phenolic compounds usually do not exist in their native form, but as esters, glycosides, or polymers. The native forms, however, require deglycosylation for their intestinal absorption, and aglycone has been considered to be the potential health-protecting/promoting form. The binding of the aglycones of phenolic compounds to bovine and(More)
The binding of therapeutically relevant synthetic retinoid derivatives to bovine and reindeer beta-lactoglobulin (betaLG) is demonstrated using fluorescence quenching and ultrafiltration/HPLC methods. Furthermore, synthesis of methyl (E)-3-[4-[(E)-2-(2,6,6-trimethylcyclohex-1-enyl)vinyl]phenyl]-acrylate 4 and(More)
Several analytical methods have been used to determine whether ligands bind to bovine beta-lactoglobulin (betaLG). The most common methods are based on fluorescence quenching. We have miniaturised this method from a quartz cell to a 96-well plate. The miniaturisation was evaluated using retinol. The binding constants between the two methods demonstrated a(More)
Beta-lactoglobulin (betaLG) is a protein that binds ligands like fatty acids and retinol into the hydrophobic pocket. Our purpose was to study bovine and reindeer betaLG as transporter molecules and compare their transport properties across Caco-2 cell membrane. The reindeer betaLG has more valuable binder characteristics than bovine betaLG because it has(More)
