Health Focus: Diabetes

Glucose is transported through the blood, powering cells throughout the body. However, if the level of glucose gets too high, it can cause the chronic problems associated with diabetes mellitus. Atomic structures have revealed how glucose levels are regulated in the body and are providing new hope for combating the disease. To learn more, browse PDB-101 resources related to diabetes.
