UC Berkeley professor Carolyn Bertozzi keeps a close watch on carbohydrates, but it's not because she's on a trendy diet. In her chemistry laboratory, Bertozzi pays close attention to the carbohydrates that dot the surface of cells.
Bertozzi, a professor of chemistry and of biochemistry and molecular biology, and her graduate students have devised new chemical tools to uncover how the sugar structures change based on various factors. Someday, their research could aid doctors in diagnosing cancer and other diseases.
