The Haworth Projection is a key concept in carbohydrate chemistry, allowing for the two-dimensional representation of sugars' three-dimensional cyclic structures. It distinguishes between alpha and beta anomers, particularly in monosaccharides like fructose, galactose, and glucose. This projection method is crucial for understanding the stereochemistry of the anomeric carbon and the behavior of sugars in solution, such as mutarotation in D-Glucose. Practical examples, including lactose, highlight the importance of mastering Haworth Projections for comprehending the complex structures and stereochemical aspects of carbohydrates.
