Written with the non-scientist in mind, this book employs the molecule and its interactions to explain the characteristics of living organisms in terms of the underlying chemistry of life. Following introductory chapters on the fundamentals of life, attention then turns to small molecules such as hormones and neurotransmitters and subsequently to macromolecules including proteins and nucleic acids. The interactions between small and macromolecules remains a central point throughout the book. These include enzymatic catalysis, hormone action, neurotransmission, regulation of metabolism, biosynt |
