N-Acetylneuraminic Acid - Acetylneuraminic Acid

5-acetamido-3,5-dideoxy- D -glycero- D -galacto - 2 -nonurosonic acid. _{C 11} H ₁₉ NO ₉ (309.27). Abbreviations: NeuNAc, NANA, etc. It is believed to be an aldol condensation product of pyruvic acid and N -acetylmannosamine. It is a representative of various sialic acids with different N -acyl groups, and is widely located at the non-reducing end of glycans in glycoproteins and glycolipids in the animal kingdom, and its anionic charge plays an important role in the expression of physiological activity. Decomposition point: 185-187 °C. -32° (water). Easily soluble in water, sparingly soluble in ethanol. Carboxyl group p K 2.6. [CAS 131-48-61]
