Galactose binding lectin domain Galactose binding lectin domain In molecular biology, the galactose binding lectin domain is a protein domain. It is found in many proteins including the lectin purified from sea urchin ("Anthocidaris crassispina") eggs, SUEL. This lectin exists as a disulfide-linked homodimer of two subunits; the dimeric form is essential for hemagglutination activity. The sea urchin egg lectin (SUEL) forms a new class of lectins. Although SUEL was first isolated as a D-galactoside binding lectin, it was later shown that it binds to L-rhamnose preferentially. L-rhamnose and D-galactose share the same hydroxyl group orientation at C2 and C4 of the pyranose ring
Collagen the form of dietary supplement or functional foods and beverages with the intent to aid joint and bone health and enhance skin health. Hydrolyzed collagen has a much smaller molecular weight in comparison to native collagen or gelatin, study suggests that more than 90% of hydrolyzed collagen is digested and available as small peptides in the blood stream within one hour. From the blood, the peptides (containing hydroxyproline) are transported into the target tissues (e.g., skin, bones, and cartilage), where the peptides act as building blocks for local cells and help boost the production of new collagen fibers. Collagen is
