WebDiastereomers that contain two or more stereogenic carbon atoms but differ in configuration at only one stereogenic center are called epimers. Thus, the diastereomers d -glucose and d -galactose are epimers because they differ in configuration only at C-4. d -Glucose and d -mannose are epimers that differ in configuration at C-2. WebFischer projections are a way to represent three-dimensional molecules in two dimensions. By following specific rules for drawing these projections, one can depict complex …
