High Quality 131-48-6 factory Sialic acid Top quality N-acetylneuraminic acid
Salic acids are nine-
N-Acetylneuraminic acid is a sialic acid nine-carbon monosaccharide commonly found in glycoproteins on cell membranes and in glycolipids such as gangliosides in mammalian cells. Studies suggest that N-Acetylneuraminic acid is useful biologically in neurotransmission, leukocyte extravasation, viral or bacterial infections and carbohydrate-protein recognition. It is believed that N-Acetylneuraminic acid, a negatively charged, non-reducing sugar, is more difficult to analyze directly. One method for its detection in serum is to cleave pyruvic acid from the molecule via N-Acetylneuraminic acid aldolase followed by colorimetric detection.
N-Acetylneuraminic acid is useful biologically in neurotransmission, leukocyte extravasation, viral or bacterial infections and carbohydrate-protein recognition. Neu5Ac is used to study its biochemistry, metabolism and uptake in vivo and in vitro. Neu5Ac is used in the development of nanocarriers.
