WebFeb 24, 2024 · Glycans are oligosaccharide chains; which are saccharide polymers, that can attach to either lipids (glycolipids) or amino acids (glycoproteins). Typically, these bonds are formed through a ... Web16.1.1 Glycoprotein synthesis. Glycoprotein synthesis occurs in two organelles in sequence such as endoplasmic reticulum and the Golgi apparatus. The carbohydrate core is attached to the protein both co-translationally and post-translationally. The ribosome bearing the mRNA which codes for the proteins attaches to the endoplasmic reticulum.
