cally coupled to neural activity Metabolism of Astrocytes and their Metabolic Cooperation with Neurons ? Glucose ? Amino acid metabolism ? Enzymes: ? glutamine synthetase(glutamateglutamine cycle)。 ? glycogen phosphorylatase (glycogen mobilization)。 ? pyruvate carboxylase (anaplerotic synthesis of oxaloacetate)。 ? cysteine sulfinate decarboxylase (synthesis of taurine)。 ? glycine cleavage system, glycine metabolism. ? Three Types of Metabolic Cooperation of Astrocytes and Neurons 1. Supply of the energy substrate lactate to neurons 2. The recycling of neuronal glutamate by the glutamateglutamine cycle 3. The supply by astrocytes of precursors for neuronal glutathione (GSH) synthesis
