Unit 5: Making Molecules—Lewis Structures and Molecular Geometries
And here's my comment: At around 20 minutes in the video, the MIT chemist talks about what made her want to switch from becoming a doctor to becoming a chemist, and her words were these:
So, when I first studied penicillin, I was amazed, I said ‘Wow, like, so this, thinking about the structure right here is how we can actually understand how it works in the body. And this is the point for me where I started that switchover from thinking I want to help people by becoming a doctor to I want help people by studying and understanding how things work on a molecular level.What stood out to me is her choosing a career based on how "I want to help people," not just what I like doing or what makes a lot of money or brings me fame, but how I can help...How great is that!
note: last period I received comments from Laura, Niles, Abigail, Connor and Zach. Good job, to them, but I expect ALL of you to watch and make a significant comment.
Monday we will practice the chem show. Bring in any extra items you will need.
Mold kills bacteria because of the penicillin it has inside of it.
ReplyDeleteA hydroxl radical can harm our DNA, which leads to aging and cancer. However, radicals are essential for life too. The same hydroxl radical is used by white blood cells to kill bacteria and viruses.

If scientists are able to stop the RnR Enzyme from reaching the Active Site then that will cause the cancer cells to stop splitting and reproducing, which is what the scientists want to do to fight cancer.

A common radical found in our bodies is the hydroxyl radical, which is an oxygen atom that is bound to a single hydrogen atom. It has 7 valence electrons, which dosen't fulfill the octet rile, and as a result, is extremely reactive. Essentially this radical electron is going to react with another molecule, really whatever it bumps into, in order to steal another electron and typically form a new covalent bond to gibe the oxygen atom its complete octet. This hydroxyl radical is harmful, and can harm our DNA, resulting in aging and even cancer, yet it is essential to life. It is used in the body in a very controlled way by white blood cells to kill invading bacteria and viruses. By understanding how radicals work, we can come up with solutions to shut down the ones that harm our health, and help in the fight against cancer.

There is an oxygen atom in rnr

An Atom within a molecule with an unpaired electron is know as a radical. Since this molecule is unpaired it is highly reactive and will soon take another molecule to complete its atom. A common radical found in our bodies is the hydroxyl radical, which is an oxygen atom bound to a single hydrogen atom.
