Phosphorylase b is an enzyme that plays a crucial role in carbohydrate metabolism, specifically in the breakdown of glycogen to glucose-1-phosphate. It is a form of glycogen phosphorylase, which exists in two interconvertible forms: phosphorylase a (active) and phosphorylase b (less active). The enzyme is primarily found in muscle and liver tissues, where it facilitates the mobilization of glucose during periods of energy demand. Phosphorylase b is regulated by allosteric effectors, such as AMP, which activates it, and ATP and glucose-6-phosphate, which inhibit its activity. The enzyme's activity is also influenced by phosphorylation, which converts it to the more active phosphorylase a form. Phosphorylase b is essential for maintaining blood glucose levels and providing energy during physical activity. Its CAS number, 9012-69-5, identifies it in chemical databases, aiding in research and application in biochemistry and medicine. Understanding its characteristics and regulatory mechanisms is vital for insights into metabolic disorders and potential therapeutic targets.
