5.2 Summary of Section 5

  1. The structural formulae of organic molecules can be divided into the carbon-hydrogen framework or skeleton, and the functional group(s). In the first approximation, the functional groups are the sites where reaction occurs, the framework remaining unreactive.

  2. This approximation works best when the framework consists of saturated carbon atoms.

2.3 Some proteins require small-molecule cofactors

Cofactors are non-protein substances that complex with particular proteins and are essential for their activity. They include prosthetic groups and coenzymes.

Coenzymes are organic molecules that bind only temporarily to an enzyme. They are often derivatives of a mono- or dinucleotide, e.g. nicotinamide adenine dinucleotide (NAD), and may serve as a vehicle for a chemical group generated or required in an enzyme-catalysed reaction. In contrast to coenzymes, prosthetic groups

Our analysis of media coverage suggested that this was an issue that received more attention in the broadsheets than the tabloids, with The Guardian and The Sun/News of the World being at the two ends of the spectrum.
