Question

In the Fischer projection of the reduction of a ribose, which carbon is reduced?

A) Carbon 1 (C1)
B) Carbon 2 (C2)
C) Carbon 3 (C3)
D) Carbon 4 (C4)

Answer 1

In the Fischer projection of the reduction of a ribose, the carbon that is reduced is A) Carbon 1 (C1).

Step-by-step explanation:

In a Fischer projection, the horizontal lines represent bonds that project out of the plane of the paper, while vertical lines represent bonds that project into the plane.

When ribose undergoes reduction, it involves the addition of hydrogen atoms to the carbon atoms in the ribose structure. The carbon atom that undergoes reduction is the one attached to the carbonyl group, and in the case of ribose, this is Carbon 1 (C1).

The reduction of Carbon 1 in ribose involves the addition of hydrogen to the carbonyl carbon, resulting in the conversion of the carbonyl group to a hydroxyl group. This reduction reaction is a key step in the synthesis of various biomolecules, including nucleotides and carbohydrates.

In summary,A) the reduction of ribose in a Fischer projection specifically occurs at Carbon 1 (C1), where the carbonyl group is present, and this reduction is significant in the context of various biological processes involving the synthesis of important biomolecules.
