Glycosylation occurs most frequently on ________ residues.
A. Alanine |
||
B. Serine | ||
C. Glutamate | ||
D. Lysine |
||
E. Asparagine |
Ans:- E. Asparagine
explanation:- glycosylation is process of addition of glycosyl group (carbohydrate) to protein. glycosylation occurs in endoplasmic reticulum (ER) and golgi apparatus. there two type of glycosylation N-linked glycosylation and O-linked glycosylation. N-linked glycosylation occurs more frequently and involved in addition of glycosyl group to asparagine. N-linked glycosylation occurs in ER and is important for protein folding and structure hence give stability to protein. O-linked glycosylation occurs in golgi apparatus and involved in protein transportation,
