application
l-asparagine is an important raw material for the production of amino acids.
asparagine is required for development and function of the brain. 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.

packing
25kg/fiber drum

storage
store it in the cool and dry place.keep it from strong light and heat.
