Glycosylation vs Glycosidation:

Glycosylation:
Glycosylation is a process in which sugar molecules are added to proteins and lipids, forming glycoproteins and glycolipids. This process occurs in the endoplasmic reticulum and Golgi apparatus of eukaryotic cells. It is an important process in protein folding, stability, and function.

Glycosidation:
Glycosidation is a process in which a sugar molecule is attached to a non-carbohydrate molecule, such as a steroid or flavonoid. This process occurs in plants, fungi, and bacteria. Glycosidation is important in the biosynthesis of many natural products, including hormones and antibiotics.

Function of Golgi Apparatus in Glycosylation:
The Golgi apparatus plays a central role in glycosylation. It is responsible for modifying and sorting glycoproteins and glycolipids before they are transported to their final destinations in the cell. The Golgi apparatus contains a series of stacked membrane-bound compartments, called cisternae, which are involved in different steps of glycosylation.

Differences between Glycosylation and Glycosidation:
- Sugar molecules are added to proteins and lipids in glycosylation, while in glycosidation they are added to non-carbohydrate molecules.
- Glycosylation occurs in eukaryotic cells, while glycosidation occurs in plants, fungi, and bacteria.
- Glycosylation is important in protein folding, stability, and function, while glycosidation is important in the biosynthesis of many natural products.
- The Golgi apparatus plays a central role in glycosylation, but is not directly involved in glycosidation.

In conclusion, glycosylation and glycosidation are two different processes that involve the attachment of sugar molecules to other molecules. The Golgi apparatus plays a central role in glycosylation, which is an important process in protein function, while glycosidation is important in the biosynthesis of many natural products.

"glycosidation" means formation of "glycoside"andand "glycosylation" means to formation of glycoside only but not directly it involves in some reaction with functional group in case in the reaction process it reacts with protein it comes out as glycoprotein or with correct it comes out as "glycoside"
