Virtually every nutrient must be biotransformed by the liver into its proper biochemical form before the nutrient can be stored, transported or used in cellular metabolism. Stores various nutrients , especially A, D, B-12 and iron for release as needed. Manufactures carnitine from lysine and other nutrients. Carnitine is the only known bionutrient which can escort fats into the mitochondria where they are used to generate ATP energy. Converts lactic acid from a toxic waste to an important storage fuel.
Lactic acid is produced when glucose is metabolized through the energy production cycle.
When excessive levels accumulate, you experience sore muscles. A healthy liver will extract lactic acid from the bloodstream and convert it into the reserve endurance fuel, glycogen. Serves as the main glucose buffer , preventing high or low extremes of blood sugar. The liver is the key regulator of blood sugar between meals due to its manufacture, storage, and release of glycogen, the starch form of glucose. When blood sugar is low, a healthy liver converts stored glycogen into glucose, releasing it into the bloodstream to raise blood sugar levels.
