Storage of glycogen is essential for glucose homeostasis and for energy supply during bursts of activity and sustained muscle work. We describe three siblings with profound muscle and heart glycogen ...

Unexplained left ventricular hypertrophy often prompts the diagnosis of hypertrophic cardiomyopathy, a sarcomere-protein gene disorder. Because mutations in the gene for AMP-activated protein kinase γ ...

Neural activity leads to the mobilization of energy from glycogen in astrocytes. A new paper reports that neurons have an ambivalent relationship with glycogen: they can synthesize it themselves, but ...

When you run, your body burns a mixture of carbohydrate and fat. Your body stores carbohydrate as glycogen in your muscles and liver (the fitter you are the more you store), which is broken down to ...

Humans carry around with them, often abundantly so, at least two kinds of fat tissue: white and brown. White fat cells are essentially inert containers for energy stored in the form of a single large, ...
