The addition to liver microsomes of various substrates, such as hexobarbital, aminopyrine, or aniline, causes two types of spectral changes. Spectrophotometric studies suggest that these changes are related to substrate interaction with a microsomal hemoprotein. On the basis of these observations, two hypotheses are suggested to explain the interaction of substrates with the liver microsomal mixed function oxidase system.
