All of the following are part of the core oligosaccharide side chain in the ER, except All of the following are part of the core oligosaccharide side chain in the ER, except

A. N-acetyl glucosamine.
B. erythrose.
C. mannose.

B.)erythrose

Explanation:

Oligosaccharides refers to complex structure formed when two or more monosaccharides are bonded together by O-glycosidic bonds. They sucrose,maltose and lactose . the glycosidic bonds in olgosaccharides are catalyzed by a specific enzymes. when oligosaccharide is attached to asparagine through a beta linkage to the amine nitrogen of the side chain, then N-Linked glycosylation is formed

Erythrose which is also known as L-thresose is a tetrose saccharide that has one aldehyde group and also part of aldose family. It has the chemical formula C₄H₈O₄. Erythrose found in all living organism and specifically it is found in blood and also in cartilage tissue. It can also be found in cytoplasm of a living cell.

D-Erythrose belongs to tetrose carbohydrate

Therefore, all of the options are part of the core oligosaccharide side chain in the ER, except ERYTHROSE.
