ANSWER:Step 1 of 6
Fischer projection:It is possible to represent the three-dimensional form of an organic molecule in two-dimensional form using horizontal lines. This representation is known as Fischer projection. The Fischer projections are mainly used to represent the two-dimensional representation of carbohydrates.
