Product Description:
Natural arginine to L-type, the product crystallized from water containing two crystal water molecules, the crystallization in ethanol is anhydrous. Because the presence of guanidine, arginine is alkaline, easy to form a salt with the acid reaction.Natural materials abound in the protamine,it is the basic components of proteins, so there is very extensive.
