Glycogen Phosphorylase b Liver Form, also known as GPhb-L, is an enzyme primarily found in the liver that plays a crucial role in glycogen metabolism. It catalyzes the breakdown of glycogen into glucose-1-phosphate, thereby releasing stored glucose for energy production. Although GPhb-L is commonly referred to by its full name, there are several synonyms to describe this enzyme. Some alternate terms include Liver Glycogen Phosphorylase b, Hepatic GPh, and Liver GPhb. These synonyms are interchangeable and are often used in scientific research, medical literature, and discussions related to liver glycogen metabolism and related disorders.
