Glycosylation is a process that attaches a sugar molecule to an amino acid or protein in the form of a glycosidic linkage. The attachment of the sugar molecule can be accomplished by either an enzymatic or chemical process. The type of glycosylation determines the type of linkage, which can be alpha-N-glycosidic (α-N), beta-N-glycosidic (β-N), or N-acetyl--galactosamine (NAG). Methylation is a process that changes one or more hydroxyl groups on a compound into methyl groups. It is usually performed with compounds containing alcohol groups (-OH) on their molecules. Click modification is a chemical reaction used to attach two chemical compounds together. It usually involves the use of copper(I) chloride, copper(II) chloride, and other reagents such as tetrabutylammonium bromide and potassium bromide. Click modification has been

Phenylethyl b-D-galactopyranoside is a galactose compound that can be hydrolyzed by esterases in the presence of water.
