DL-Glyceraldehyde is primarily used in biochemical research as a reference compound for studying carbohydrate metabolism and stereochemistry. It serves as a model substrate in enzymatic reactions involving aldoses and plays a role in understanding the behavior of sugars in metabolic pathways such as glycolysis and the pentose phosphate pathway. It is also employed in the synthesis of more complex sugars and chiral molecules in organic chemistry. Due to its reactive aldehyde group, it participates in glycation reactions, making it useful in studies related to protein modification and advanced glycation end-products (AGEs) associated with aging and diabetes. Additionally, DL-Glyceraldehyde is used in educational settings to demonstrate concepts of enantiomers and optical activity in organic chemistry.
