Product Description
Sialic acid, also known as N-acetylneuraminic acid, English referred to as SA, Neu5Ac or NANA. It added into infant milk powder can increase babys' intelligence and memory, enhance the immune ability. The sialic acid as raw material can be used in the development of important drugs, which have very good effects on anti-influenza, treatment of senile dementia, promote intestinal absorption of vitamin and mineral, anti-tumor and anti-inflammation. Moreover, sialic acid can also be used as raw material of health care products etc.

N-Acetylneuraminic acid / Sialic AcidSialic acid is a commonly used generic term for O- or N-substituted derivatives of the nine-carbon monosaccharide neuraminic acid. N-Acetylneuraminic acid is the most common derivative found in mammalian cells, and sialic acid is often used to refer specifically to this molecule. The abbreviations Neu5Ac or NANA are also used.

N-Acetylneuraminic acid is widely distributed in human tissues and is found in glycoproteins on cell membranes and in glycolipids such as gangliosides, and is involved in diverse biological functions including neurotransmission, leukocyte extravasation, viral or bacterial infections and carbohydrate-protein recognition events leading to cell adhesion.1,2 N-Acetylneuraminic acid is also found in several body fluids such as saliva, urine, amniotic fluid and cerebrospinal fluid.

APPLICATION
N-Acetylneuraminic acid is usually called sialic acid or Neu5Ac,naturally widespread carbohydrate with numerous biological functions, including blood protein half-life regulation, variety of toxin neutralization, cellular adhesion and glycoprotein lytic protection. Starting reagent of biochemical derivatives for the synthesis pharmaceuticals. 
Sialic acid is a derivative of a nine-carbon monosaccharide.
Sialic Acid was named from the Greek Sialos for Saliva. It is the negative charge of this ubiquitous chemical that is responsible for the slippery feel of saliva and mucins coating the body's organs. Despite its role of acting as 'decoy' for invading pathogens, sialic acid is increasingly becoming known as an agent necessary for mediating ganglioside distribution and structures in the brain. Work in the 1980's identified sialic acid supplementation in (suckling) rats to alter behaviour and increase performance in various mazes, s esting a role in learning and memory. However work in out lab is focussing on the role of virility that sialic acid endow.
With the use of adult rat models, we have shown that sialic acid (namely the NeuAc form) acts as an agent to increasing the number of copulations between mating pairs. A transgenic rodent with reduced sexual appetite (kindly donated by the Kitawaga lab, Japan) was used to see whether oral and intraperitoneal doses of sialic acid increased sexual drive. Within one week the number of copulations of this rat model increased to amounts close to that of rats of virility. Numerous other mating pairs have been set up and we are currently waiting for the exciting results.
