<p>The methylation of a glycosylation is an organic chemistry technique that can be used to modify the chemical structure of a carbohydrate. A glycosylation is the reaction between an alcohol and a sugar, which produces a glycoside. The addition of methyl groups at specific positions on the sugar molecule can lead to improved properties such as increased stability, increased solubility, or increased uptake by cells. This process has been shown to produce compounds with more desirable pharmacological properties than their parent compounds. Click chemistry is a versatile and powerful method for modifying carbohydrates. It involves the use of copper-catalyzed azide-alkyne cycloaddition reactions to form carbon-nitrogen bonds in place of conventional amide linkages in peptides and proteins. Carbohydrates are modified using this method by attaching small molecules such as fluorine atoms onto one or more carbons in the carbohydrate structure. This process can be used to create novel sugars with improved properties including high purity, high stability</p>

<p>Methylation is the addition of a methyl group to a molecule. The mannobiose-BSA is a methylated derivative of mannobiose, which has been modified by adding BSA.
