uronic acid meaning in Hindi

Examples

1. It is not found in nature, but its uronic acid, iduronic acid, is important.
2. Ester linkages arise between oxidized sugars, the uronic acids, and the phenols and phenylpropanols functionalities of the lignin.
3. Potassium permanganate is added to react with the unsaturated compounds ( lignin and uronic acids ) in the pulp and back-titrated.
4. The chains are long, linear carbohydrate polymers that are negatively charged under physiological conditions due to the occurrence of sulfate and uronic acid groups.
5. Jorpes discovered the structure of the heparin polysaccharide in 1935, identifying that it is a highly sulfonated polymer of glycosaminoglycoglycan ( GAG ) and uronic acid.
6. These comprise 2-aminosugars linked in an alternating fashion with uronic acids, and include polymers such as heparin, heparan sulfate, chondroitin, keratan, and dermatan.
7. Position of N-acetyl, N-sulfate, and O-sulfate groups in these uronic acids can vary, as can the branching patterns of the chain.
8. A laboratory synthesis of a uronic acid from an aldose requires protecting the aldehyde and hydroxy groups from oxidation, for example by conversion to cyclic acetals ( e . g ., acetonides ).
9. There is no internationally accepted molecular standard for the composition of heparin, as it is a complex polymer of GAG units and uronic acids ( including D-glucuronic acid, L-iduronic acid, and D-glucosamine ).
10. Next, C-5 uronyl epimerase coverts d-GlcA to l-IdoA followed by 2-" O " sulfation of the uronic acid sugar by 2-" O " sulfotransferase ( Heparan sulfate 2-O-sulfotransferase ).
