protein-synthesis-epic-cellular-level Protein Synthesis Epic Cellular Level. Directed in 1971 by Robert Alan Weiss for the Department of Chemistry of Stanford University and imprinted with the free love aura of the period this short film continues to be shown in biology class today. It has since spawn a series of similar funny attempts at vulgarizing protein synthesis. Narrated by Paul Berg 1980 Nobel prize for Chemistry.

Question Protein Crystal Molecules Question

I have this question-- can anyone solve it, and how did you solve it? To the nearest power of 10, how many protein molecules with a molecular
weight of 25,000 are found in a crystal that is 3 mm on each side?
(Assume that a crystal is 50% water and that the density of a protein is
the same as that of water)

thanks!

Default Re: Protein Crystal Molecules Question

The key here is, "assume the density of a protein is the same as that of water".

This gives you a conversion between volume (of the cube) and mass (of the protein).
