What knowledge have you connected with past knowledge?

From the past to present, I am learning each day. All the topics covered in class, I was familiar with before. I learned that proteins are composed of four structural components. These structures included Primary structure consisted of basic order sequences of amino acid, secondary structure composed of amino acid arranged in beta sheet and alpha helix, tertiary was the folding of the structure in 3D shape and quaternary consisted of subunits, which were dimmers, trimers and tetramers. Alpha helix had a hydrogen bond that made it stable and the side chains were found on the outer parts of the helix. If the helix got larger it couldn’t arrange in shape due to the bulky side groups. Beta pleaded sheet consisted of intrachain and interchain. Alpha helix and beta sheet could merge to create a supersecondary structure (motif). Myoglobin was an example of tertiary structure and hemoglobin was an example of quarternary structure.

I also learned that most enzymes were considered protein but only some proteins were considered enzymes. Enzymes were highly specific which catalyzed only on certain enzymes. When enzymes were being catalyzed, their activation energy would lower and their rate of reaction would increase. Their transition state was much more stable than the uncatalyzed enzymes. The rate of a chemical reaction of the enzymes would increase if the temperature increased. Enzymes would denature if the rate of the biochemical reaction along with the temperature reached their limit.
