WebSep 30, 2024 · The Glucose-Alanine Cycle also known as the alanine cycle or Cahill cycle, is the series of reactions in which amino groups and carbons from muscle are trans... WebMay 23, 2024 · The cycle uses alanine released by the muscle and deaminated by the liver to produce glucose via gluconeogenesis. This glucose is transported to the muscle where it is oxidized to pyruvate that in turn is converted back to alanine. The cycle is an important defense against hypoglycemia during starvation.

WebThe cycle is completed when glucose returns to muscles, is metabolized to pyruvate and transaminated to Ala. The glucose-alanine cycle facilitates the utilization of muscle amino acids in the liver during fasting, starvation, and traumatic stress. Ala accounts for more than a quarter of total amino acids taken up by liver from circulation.
