Kevin, Indira and Taralyn Tan's lastest electronic book is aimed at helping students at all levels of biochemistry to learn in a fun and engaging format.
- Where a good chemical catalyst might accelerate a reaction by a few orders of magnitude, the speed of the best enzyme catalyst boggles the mind, boosting reaction rates by 1024 - over 1 trillion trillion times faster than an uncatalyzed one. In this chapter we explore the ways in which the process of enzymatic catalysis occurs.
- The elucidation of the structure of DNA provided greater insights into how traits might be encoded in a molecule, and the ways in which the information is used by cells. As we learn more about this topic, scientists have remarked on how the information in our DNA resembles the programs that drive computers. While this analogy is a simplification, there is definitely a sense in which, as Richard Dawkins put it, “the machine code of the genes is uncannily computer-like.”
- The traditional approach used by biochemists for the study of these things is to isolate molecules, enzymes, DNAs, RNAs, and other items of interest so they can be analyzed independently of the millions of other processes occurring simultaneously. Today, these approaches are use with newer methods that allow us to understand events inside cells on a larger scale. In this section we take a brief look at some commonly used methods used to study biological molecules and their interactions.
