neuraminic acid मीनिंग इन हिंदी

उदाहरण वाक्य

1. For example, N-acetyl-neuraminic acid, Neu5Ac, is typical in human glycoproteins.
2. Among their many biological functions, these structures are substrates for neuraminidase enzymes which cleave neuraminic acid residues.
3. The sialic acid family includes 43 derivatives of the nine-carbon sugar neuraminic acid, but these acids unusually appear free in nature.
4. Polylactosamine chains on O-linked glycans are often capped by the addition of a sialic acid residue ( similar to neuraminic acid ).
5. Modification reactions may involve the addition of a phosphate or acetyl group onto the sugars, or the addition of new sugars, such as neuraminic acid.
6. It is usually present on cell surfaces in a cryptic form covered by N-acetyl neuraminic acid moieties and released into circulation in many different cancers.
7. The symbol commonly used for neuraminic acid is "'Neu "', and the residue is typically found with additional chemical modifications in biological systems.
8. The name " neuraminic acid " was introduced by German scientist E . Klenk in 1941, in reference to the brain lipids from which it was derived as a cleavage product.
9. Even though the alpha and beta subunits of lysosomal hexosaminidase can both cleave GalNAc residues, only the alpha subunit is able to hydrolyze G M2 gangliosides because of a key residue, Pro-283 which is absent in the beta subunit, serves as an ideal structure for the binding of the G M2 activator protein ( G M2 AP ), and arginine is essential for binding the N-acetyl-neuraminic acid residue of G M2 gangliosides.
