Utilization of Neuraminic Acid Receptors by Mycoplasmas [PDF]
Journal of Bacteriology, 1969 Erythrocytes and H-HeLa cells were treated with neuraminidase and then compared with untreated cells for their ability to adsorb to mycoplasma colonies or be agglutinated by suspensions of the mycoplasmas. Of the 17 mycoplasma serotypes examined, only 4 were found to use neuraminic acid receptors; these were Mycoplasma ...

NEURAMINIC ACIDS IN THE CEREBROSPINAL FLUID OF SCHIZOPHRENIC AND OLIGOPHRENIC PATIENTS
American Journal of Psychiatry, 1960In a preceding note( 1) we have described a new method for determining quantitatively neuraminic acids (NA) in cerebrospinal fluid (CSF). This method allows us to appraise both the free fraction and the protein-bound fraction of the NA, and, by means of anion-exchange resins, makes it possible to eliminate the certain cause of errors by doing away with

Publisher Summary The members of the group, neuraminic acid and its higher acylated derivatives, the so-called “sialic acids,” are found widely distributed throughout the animal kingdom in mucopolysaccharides, mucoproteins, and lipopolysaccharides (mucolipids)-very often in association with D-glucosamine and D-galactosamine.

Dietary sialic acids: distribution, structure, and functions
Critical reviews in food science and nutrition, 2023Sialic acids (Sias), a group of over 50 structurally distinct acidic saccharides on the surface of all vertebrate cells, are neuraminic acid derivatives. They serve as glycan chain terminators in extracellular glycolipids and glycoproteins. In particular,

Studies on the Biosynthesis of Neuraminic Acid
Nature, 1956IN recent years neuraminic acid1 and several of its derivatives, such as sialic acid and lactaminic acid, have been shown to be constituents of mucoproteins, gangliosides and related naturally occurring substances. Although the chemical structure of neuraminic acid has not been established as yet, its elementary composition and some of its chemical ...

A fast chemoenzymatic synthesis of sialylated oligosaccharides containing C5-modified neuraminic acids is reported. Analogues of GM3 and GM2 ganglioside saccharidic portions where the acetyl group of NeuNAc has been replaced by a phenylacetyl (PhAc) or a

Neuraminic Acid Derivatives as Anti-Influenza Drugs [PDF]
Molecules Online, 1998 Influenza types A and B both cause serious disease in man; vaccines are in use but must be reformulated each year in response to antigenic variation and are frequently ineffective against new influenza variants. Influenza viruses are enveloped RNA viruses which contain two major surface glycoproteins: hemagglutinin (HA) and neuraminidase (NA, EC 3.2.1 ...

Derivatives of neuraminic acid 1,2 (or sialic acids) are widely distributed in tissues. In brain, neuraminic acid is found in especially high concentration in gray matter, 3,4 the pineal body, 5 and the hypophysis. 6 As a component of gangliosides, N-acetylneuraminic acid accumulates in the brains of patients with infantile amaurotic familial idiocy. 7,
