Glycofunctional analysis is a research method that aims to systematically evaluate and understand the functions and effects of sugars and their derivatives in organisms. Glycofunctional analysis can help us understand the biological functions of sugars, reveal the interactions between sugars and other biological molecules (such as proteins and lipids), and understand their mechanisms of action in biological processes. In drug development, effective sugar-related therapies or targeted therapeutic strategies can be designed by analyzing the functions of sugars.
