Additionally, thyroid hormones bind to DNA receptors and activate genes associated with metabolic processes. 30. This allows for glucose to continue moving from the blood to the cells where it is needed. This prevents the continued breakdown of proteins that serve as carbon sources for gluconeogenesis. If not, the excess glucose is stored as glycogen in the liver and muscle cells, or as fat in adipose tissue; excess dietary fat is also stored as triglycerides in adipose tissues. This acetoacetyl CoA is subsequently converted into β-hydroxybutyrate, the most common ketone in the body.
