Understanding molecular behaviour

Are the following statements true or false? If false, explain why.

a) In most globular proteins, the nonpolar amino acids tend to be concentrated at the surface of the protein.

b) A small organic molecule required by an enzyme in order for the enzyme to be a functional catalyst is known as a vitamin.

c) Lipids that are solids at room temperature tend to have more double bonds than liquids at room temperature.

Solution Preview

a) TRUE. In globular proteins a polar side chain (which contains a lot of non polar bonds like C-C bonds) are buried in the centre of the protein while polar groups (or polar amino acids) are ...

Solution Summary

This solution explains in 134 words polar side chains in globular proteins and how this interacts with water, how vitamins are related to enzymes and co-enzymes, and the melting point of saturated chains.
