    Why? It’s just constructive criticism. Talking about peptide bonds and proteins you cannot omit the crucial resonance structures. A mention of Ramachandran plots also would be very useful.

    Mesomery is not an English expression, sorry for that. For you it’s resonance and resonance structures.

    Americas elite …
    Americas elite don’t necessarily go to MIT. Most top students go where they can get scholarship money first. However, I would say that US medical schools no matter the name have elite students though. If you are talking elite as in money, then MIT is a good place for science. I know a guy who went to MIT who was pretty bright. I get good grades myself, but don’t like my school because there are a lot of foreign professors, and some of them are very hard to understand.

    These students are …
    These students are supposedly Americas elite. But we stupid Europeans at their level would ask why can a proton can be abstracted from the carboxylic group but not from the amino group the polarization is similar given the electronegativities of nitrogen and oxygen.

    He writes amino – …
    He writes amino -NH2 and acid H+, he should have told someting about the carboxylic group -COOH and why it acts as a proton donor (stabilizing effect of mesomery). Mesomery is crucial to the explanation of a peptide bond.

    But he’s a brilliant showman.

    In German Zwitter means hermaphrodite. In solid state chemistry it would be very nice to show some gel electrophoresis and the connection to the isoelectric point.

    Strange, some things he’s telling we are teaching in Switzerland to grammar school students. A better depiction of the D – and L- form of amino acids would have been with the help of the Fischer – Projection. In solid state chemistry he could have shown chiral quarz crystals. A nice introduction to chirality is to show “enantiomeric” hop plants, tails of piglets, snail houses and cork screws.

    They can be found from the OCW website (on right), but they are audio only. It’s a shame, Lec 32 would have had batteries and fuel cells.
