Question

Hello,

please confirm my answers based off the picture:

- The Nucleobase should be Pyrimidine instead of purine.

- I think the structure is a nucleotide but what would make it not a nucleoside?

- The 5-member sugar ring is a ribose instead of deoxyribose.

- 6-member sugar ring is cyclic D-Glucose comapred to deoxysugar or an epimer of cyclic D-Glucose.

Answer 1

it uracie (found in RNA) is a pyrimidine ba3e. O House a pu Hodka OH ey C n ! 3 NII TOH H & 12h on Deoxyribose Ribose. so in this picture (in question? the 5-member ring is Ribose. - a 6 Nucleoside = Nitrogenous base attached to sugar Nucleotide - nimogenous base e sugar & Phosphate group it is a Nucleotide. бено # OH H-C-OH HOH →H-04.00 HOFO HO HYOH H FOH 04/ "CH₂OH glucose LIH 204H d-Deglu.copyranoje D-

But the given structure bit Tot H This is l-epimer of a-D- glucose. This is structure of x-D-manose : 6 member sugen rung is an epimer of cyclic -o- glucose
