The complete name of the sugar shown is to be given. Concept introduction: The pyranose form is a cyclic hemiacetal form with a six membered ring formed by the nucleophilic addition of the â€“OH group on C 5 to the C 1 carbonyl group. The furanose form is a cyclic hemiacetal form with a five membered ring formed by the nucleophilic addition of the â€“OH group on C 5 to the C 2 carbonyl group. The orientation of â€“OH group differs in Î±- and Î²- anomers. In the Î±- anomer the OH on C 1 is cis to the â€“OH at the lowest chirality center in Fischer projection while in Î²- anomer the â€“OH on C 1 is trans to the â€“OH at the lowest chirality center in Fischer projection. D sugars have the â€“O- at C 5 on the right in the uncoiled form while L sugars have -O- at C 5 on the left. To give: The complete name of the sugar shown.

Interpretation Introduction

Interpretation:

The complete name of the sugar shown is to be given.

Concept introduction:

The pyranose form is a cyclic hemiacetal form with a six membered ring formed by the nucleophilic addition of the â€“OH group on C₅ to the C₁ carbonyl group. The furanose form is a cyclic hemiacetal form with a five membered ring formed by the nucleophilic addition of the â€“OH group on C₅ to the C₂ carbonyl group.

The orientation of â€“OH group differs in Î±- and Î²- anomers. In the Î±- anomer the OH on C₁ is cis to the â€“OH at the lowest chirality center in Fischer projection while in Î²- anomer the â€“OH on C₁ is trans to the â€“OH at the lowest chirality center in Fischer projection.

D sugars have the â€“O- at C₅ on the right in the uncoiled form while L sugars have -O- at C₅ on the left.

To give:

The complete name of the sugar shown.

If possible, replace an H atom on the a carbon of the molecule in the drawing area with a methyl group substituent, and replace an H atom on the ẞ carbon with a hydroxyl group substituent. If one of the substituents can't be added for any reason, just don't add it. If neither substituent can be added, check the box under the drawing area. en HO OH
