👉 Pyocyst is a type of protein in the human body that is responsible for regulating blood sugar levels. It consists of two proteins, a "pyroglutinin" and a "pyruvate kinase," which work together to control how much glucose (a form of sugar) is broken down into energy by the liver. If there's too much glucose in the bloodstream or if your body isn't able to use it properly, this can lead to high blood sugar levels.
