Abnormal fat metabolism underlies heart problems in diabetic patients
...iabetic hearts run mostly on fats for fuel because glucose
isn't readily available to them," says Richard Gross, M.D., Ph.D., director of the Division of Bioorganic Chemistry and Molecular Pharmacology and professor of medicine, of chemistry and of molecular biology and pharmacology. "Unfortunately, this cha...
