diheme

Example:Biporphyrins, like dihemes, are often found in components of biological electron transport chains.

Definition:A biomolecule that consists of two porphyrin rings or cyclic tetrapyrroles. Porphyrins are nitrogen-containing macrocyclic compounds that are found in proteins and enzymes that are important for biological electron transport.

Example:Diheme proteins, such as cytochromes, are vital for cellular respiration and electron transport.

Definition:A specific type of hemoprotein that contains two heme groups, which are crucial for its role in electron transfer and redox reactions.
