Chitoheptaose is an oligosaccharide derived from the exoskeletons of crustaceans such as crabs, shrimp, and lobsters. It exhibits antioxidant, anti-inflammatory, and anti-apoptotic properties, making it useful for cardiac studies, particularly myocarditis research. Chitoheptaose offers cardioprotective benefits, enhancing cardiac parameters [left ventricular internal diameter, end-systolic and end-diastolic dimensions, ejection fraction, and fractional shortening], and modulating inflammatory cytokines (IL-1β).
