we are a good supplier for sialic acid for years, from 2007 to now, we supply sialic acid from gram to metric ton.
now sialic acid begin a good amount in china, and we send the product to USA, UN and west europe.
some of my customers visit us in CPHI China in 2010 to draw the contract of sialic acid, following is the picture
1,Using proprietary scientific processes, Purer Source Bird’s Nest Sialic Acid, Collagen and Epidermal Growth Factor (EGF) are delivered deep into the layers of your skin, restoring your skin’s natural radiance and glow
2,Sialic acid-rich glycoproteins (sialoglycoproteins) bind selectin in humans and other organisms
3,Sialic acid also plays an important role in human influenza infections
4,Many bacteria also use sialic acid in their biology, although this is usually limited to bacteria that live in association with higher animals (deuterostomes). Many of these incorporate sialic acid into cell surface features like their lipopolysaccharide and capsule, which helps them evade the innate immune response of the host. Other bacteria simply use sialic acid as a good nutrient source, as it contains both carbon and nitrogen and can be converted to fructose-6-phosphate, which can then enter central metabolism.
