Chapter 15, Problem 15.50AQAP

Interpretation Introduction

Interpretation:

“What are the differences in the fisher projection of D -fructose and D-glucose.” should be explained

Concept introduction:

► Carbohydrates are organic compounds contain poly hydroxyl group along with either aldehyde or ketone functional group.

► Fischer Projections:

As an alternative of drawing a tetrahedron with two bonds in the plane, one in front of the plane, and one behind it, the tetrahedron is dumped so that both horizontal bonds appear forward which drawn on wedges and both vertical bonds move behind which drawn on dashed lines. This structure is then reduced by a cross formula, also called a Fischer Projection Formula. In a Fischer Projection formula, therefore,

• A carbon atom is placed at the junction of the two line of the cross.

• The horizontal bonds occur forward, on wedges.

• The vertical bonds move back, on dashed lines.
