Only recently was it discovered that amino acids, the building blocks of proteins, exist in two different forms: L- and D-forms. While all natural proteins consist exclusively of L-amino acids, the ...

Mammalian metabolism is regulated by opposing cAMP and insulin signaling pathways, which are activated in the fasting and fed states, respectively 1. During fasting, hepatic gluconeogenesis is ...

Glucagon increases the production of glucose by increasing glycogenolysis and gluconeogenesis in the liver, and by reducing glycogenesis and glycolysis. The release of glucagon in response to food ...

One of the most confusing aspects for patients with type 2 diabetes mellitus is that they have high fasting glucose levels. This is because in these insulin-resistant patients, glucose production by ...

Schematic diagram of the mechanism by which HYAL1-mediated HA degradation regulates mitochondrial O-GlcNAcylation in postprandial hepatocytes through the redistribution of the HA catabolism metabolite ...
