👉 Zophosis is a term used in the field of biochemistry, specifically referring to an enzyme that catalyzes a reaction called glycogen phosphorylase (GPK), which plays a crucial role in regulating blood sugar levels and glucose metabolism. It works by breaking down glycogen into glucose, which can then be converted back into glycogen for storage or release into the bloodstream. This process is essential for maintaining normal blood sugar levels throughout the day and night.
