<p>Blood group B trisacchharide-APE-HSA is a synthetic carbohydrate that inhibits the synthesis of complex carbohydrates. The methylation of saccharides and polysaccharides can be accomplished by the addition of an amine to the 3′ hydroxyl group. In this reaction, the sugar is attached to a protein carrier (e.g., human serum albumin) via an amide bond, which prevents its degradation by proteases in the body. The modification of saccharides and polysaccharides is also accomplished through click chemistry, which is based on copper catalysis. This process involves attaching two functional groups through a copper-mediated reaction, forming a new carbon-carbon bond. Modification of saccharides and oligosaccharides can be accomplished using either chemical or enzymatic methods. Sugar modification can be achieved using high purity enzymes that have been custom synthesized for specific purposes (e.g., glycosylation). Carbohydrate modification can</p>
