Monosacáridos

Modification of glycosylation is a process that can be used to alter the properties or characteristics of a carbohydrate. This modification is done by adding a sugar molecule to the existing glycosidic linkage, modifying the chemical structure. Modification of glycosylation has been shown to increase the bioavailability and decrease the rate of clearance of drugs in animal models. This process can also be used to synthesize oligosaccharides, which are carbohydrates consisting of two to nine monosaccharide units. Monosaccharides are sugars composed only of one kind of sugar molecule, such as glucose or fructose. Methylation and fluorination are two types of chemical modifications that can be performed on saccharides (sugars). These modifications have been shown to increase the stability and solubility of saccharides while decreasing their immunogenicity.
