21. The exact principal of collagen binding to mannose receptor is not known so far. 22. Leguminous lectins consist of two or four bind either glucose, mannose or galactose. 23. It acts as an intermediate step between GDP-Mannose and GDP-Frucose. 24. Mannose is partially excreted in the urine.25. ConA interacts with the surface mannose residues of many microbes, like the bacteria" 26. Increased viral loads in cases of congenital mannose -binding lectin deficiencies have been reported. 27. It also contains high-mannose glycans. 28. Mannose receptor provide reception of extracellular ligands.29. The C-linkage refers to the covalent attachment of mannose to a tryptophan residue. 30. The challenges in constructing ?-mannose linkage have been well documented in several reviews.
