The composition of cortical granules is diverse and includes various enzymes, proteins, and other molecules. Key components include: - Proteases: Enzymes that degrade proteins in the zona pellucida. - Glycosidases: Enzymes that modify glycoproteins. - Peroxidases: Enzymes that may play a role in cross-linking proteins. - Mucopolysaccharides: Polysaccharides that contribute to the structural changes in the zona pellucida.
