An amino acid residue (other than glycine) has no symmetry elements. The general operation of conversion of one residue of a single chain into a second residue equivalent to the first is accordingly a rotation about an axis accompanied by translation along the axis. Hence the only configurations for a chain compatible with our postulate of equivalence of the residues are helical configurations.

I made use of the college library by borrowing books other than scientific books, such as all of the plays by George Bernard Shaw, the writing of Edgar Allan Poe. The college library helped me to develop a broader aspect on life.

It will be possible, through the detailed determination of amino-acid sequences of hemoglobin molecules and of other molecules too, to obtain much information about the course of the evolutionary process, and to illuminate the question of the origin of species.

Life ... is a relationship between molecules.

In teaching, you do not want to COVER things, you want to UNCOVER them. The best way to get good ideas is to have lots of ideas.

It was obvious-to me at any rate-that the answer was to why an enzyme is able to speed up a chemical reaction by as much as 10 million times. It had to do this by lowering the energy of activation-the energy of forming the activated complex. It could do this by forming strong bonds with the activated complex, but only weak bonds with the reactants or products.

Humanism is a philosophy of joyous service for the greater good of all humanity, of application of new ideas of scientific progress for the benefit of all.
