Golgi complex is a cell organelle present in eukaryotes but not in prokaryotes. liver cells and nerve cells have many Golgi complexes. Golgi complexes play important functions especially related to cell secretions. Glycosidation of lipids by modifying N-linked and O-linked oligosaccharides and proteins is one of the main function.
So, the correct answer is 'Golgi body

The chemical modification of substances like glycosidation of protein and lipid can occur in various biological processes and cellular compartments. Some of the common locations where these modifications occur include:
1. Endoplasmic reticulum (ER): Many proteins and lipids undergo glycosidation in the ER, where they are synthesized and processed. The addition of sugar molecules to proteins or lipids in the ER is known as N-glycosylation (for proteins) or glycolipid biosynthesis (for lipids).
2. Golgi apparatus: The Golgi apparatus further processes and modifies proteins and lipids that have been glycosidated in the ER. This includes the addition of additional sugar molecules or trimming of existing sugar chains. This process, known as O-glycosylation, involves the addition of sugar molecules to specific amino acid residues in proteins.
3. Cytoplasm: Some proteins and lipids can undergo glycosidation in the cytoplasm. For example, cytoplasmic glycosylation of proteins can occur in certain disease conditions, such as cancer.
4. Cell membrane: Glycosidation of lipids can occur at the cell membrane, where specialized enzymes add sugar molecules to lipids, forming glycolipids. These glycolipids play important roles in cell signaling, cell adhesion, and immune recognition.
Overall, glycosidation of proteins and lipids can occur in various cellular compartments, depending on the specific modification and the biological context.
