Preprint. Glycosylation is a very common modification of protein and lipid, and most glycosylation reactions occur in the Golgi. It requires an amazing number of enzymes, chaperones, lectins and transporters whose actions delicately secure the fidelity of glycan structures. N -glycan processing is carried out in endoplasmic reticulum and the Golgi body. 2021 Apr 1:2021.04.01.438120. doi: 10.1101/2021.04.01.438120.

Jaeken, in Reference Module in Biomedical Sciences, 2016 Abstract. Abundant evidence has been accumulated that a well-organized Golgi structure is required for its proper functions, especially protein glycosylation. Initial trimming of the precursor molecule occurs in the ER and the subsequent processing occurs in the Golgi. COG5 -congenital disorder of glycosylation (COG5 -CDG, formerly known as congenital disorder of glycosylation type IIi) is an inherited condition that causes neurological problems and other abnormalities. It contains glucose, mannose and n-acetylglucosamine molecules. Golgi membranes are studded with glycosyltransferases, glycosidases, and nucleotide sugar transporters arrayed in a generally ordered manner from the cis-Golgi to the trans-Golgi network (TGN), such that each activity is able to act on specific substrate(s) generated earlier in the pathway. Although the transfer of initial sugar (s) to glycoproteins or glycolipids occurs in the ER or on the ER membrane, the subsequent addition of the many different sugars that make up a mature glycan is accomplished in the Golgi.
