Researchers design a new highly-selective tool to study 'undruggable' proteins through the sugars they depend on

Sugar has been called "evil," "toxic," and "poison." But the body needs sugars, too. Sugar molecules help cells recognize and fight viruses and bacteria, shuttle proteins from cell to cell, and make sure those proteins function. Too much or too little can contribute to a range of … | Continue reading
