👉 In biology, a dimorphic cytochrome is a pigment that changes color depending on the light source or environment in which it is produced. This can occur due to differences in the chemical composition of the pigment, such as the presence of a single amino acid or different amounts of an enzyme. Dimorphocalyx (or dimorphic cytochromes) are a type of dimorphic cytochrome that have two different forms depending on whether they are produced under normal conditions or when they are exposed
