Chemoenzymatic Synthesis of Well‐Defined α(2,8)‐ and α(2,9)‐Linked Oligosialosides
Angewandte Chemie, Volume 138, Issue 36, 1 September 2026.Well‐defined α(2,8)‐ and α(2,9)‐linked oligosialic acids of different lengths can be prepared by employing recombinant bacterial polysialyltransferases in combination with chemically modified CMP‐Neu5Ac derivatives. After transfer, a sialoside is formed bearing an artificial entity, which blocks further glycosylation.

Sialic Acid (N-Acetylneuraminic Acid) in Human Serum
Clinical Chemistry, 1964 Abstract A simple spectrophotometric method is described for the sialic acids which utilizes the reaction with resorcinol and extraction with butyl acetate-n-butanol as a solvent. Normal values for adults, utilizing N-acetylneuraminic acid as a standard, were found to be 60 ± 10.4 mg./100 ml. Values for newborn babies averaged 40.4 ± 5.7.

N-Acetylneuraminic Acid (NANA) in Measles Virus
Experimental Biology and Medicine, 1978 The envelope glycoproteins and glycolipids of paramyxoviruses appear to be derived from the host cell plasma membrane during viral release (1, 2). Measles envelope glycoprotein spikes effect attachment of the virion to cell surfaces, thereby initiating either he-magglutination (HA) or infection (3,4).
