After checking out the bet sheets of proteins, I realize that the hydrogen bonds runs between the peptide bonds. The R groups
are still sticking out of the plane of the sheets. The triple helices of the fibrin suggest why Linus Pauling thought
DNA had three strands and the phosphates were inside with the nitrogenous bases outside. While it described proteins, it did
not describe nucleic acids.
Kevin Ahern is very helpful in understanding biochemistry. I have decided to stay with
the more advanced course because the lower course is not worth my time.
Another aspect reveals how hormones work.
It gives a clue how those physiological terms work. Chemical laboratories from evolution run continually, leaving clues how drugs
could work as well.
