  B.Description

• The nervous system requires asparagine. It also plays an important role in the synthesis of ammonia.
• The addition of N-acetylglucosamine to asparagine is performed by oligosaccharyltransferase enzymes in the endoplasmic reticulum.This glycosylation is important both for protein structure and protein function.
