These teachers are chalk wizards! Thankfully this teacher doesn't teach like she's asleep like so many others. She has energy and that helps with learning

Thank you for the wonderful lectures. I majored in Biology 30 years ago, nice to have a refresher.

The way in which Dr. Imperiali explains things is amazing, her enthusiasm and knowledge is inspiring, makes the learning process so interesting and easy. Everything is so well explained. Great energy literally :) Thank MIT for sharing this!

with the proper background knowledge, I found myself having all the preliminaries to go forward with the chemical nature of life. I am incredibly grateful

Such a beautiful demonstration, A 9th grade student can also understand this easily, Thanks to MITOpenCourseware

MIT has some great courses. If you are interested in mathematics, Gilbert Strang is a brilliant teacher. He was taught a course on Linear Algebra and a student ran through the lecture hall in an ape suit (must have been around the time of Halloween). He was took it all in stride.. made a pithy comment and continued with the lecture!

Allow me to say that you are not only an amazing lecturer but also passionate

Wow nothing less. This lecture really made the molecules of organic organisms come to life. It was down to earth and a really beautiful explanation about molecules in organisms. THANK YOU !

Very good lesson, doing a biochem course in september this is good prep thank you.

Many thanks to all of Great MIT's Professors.

I love this professor so much

Just wow👏. Thank you for giving us access to these wonderful lectures😍

What a refresher! This saved me

How come this have so few likes? This is brilliant and explained very well. I wondered, how those lipid bilayers would form in nature, to get the "cell life" started. Then I got the answer that they self -assemble (when the necessary conditions are met, I assume). I consider the primordial soup a pretty interesting place. Especially the early days :-D

Thank you for rejuvenate my interest in chemistry

I am an Engineer in IT and AI. AI caused be to learn nueroscience and then in turn biology. I think you will find it amazing that a person who found it pride to NOT to learn biology is doing this course.

Thank you. You help me reason better :)

Thank you so much, its very impressive, the drive the interest an the dedication of the Instructor: Barbara Imperiali.

Perhaps that’s unfair to other colleges and universities? Professor Imperiali seems like one in a billion. You either get her, like MIT did, or you get some who’s just not for a world class superstar professor like she is.

It's my dream to sit inside this class one day🥰🥰

This is great. I miss school. Wish I could go back b4 40 and really put my foot in it

General chemistry (CHE 105) covers exactly that

At 22:51, defining the reaction that forms amide, I think she forgets to add in the C (carbon) on the right hand side. The reaction is not balanced without it, even when assuming H2O as a by-product. Compare it with the slide she shows a few minutes later, there the C is indeed included. Can someone confirm?

Love from India 🇮🇳 ♥ ❤ 💕 💗 💖 mam ,very very thankful for this lacture mam.

Biochemistry is so fascinating. I'm 28 and regret not going into it.

Is there an online resource/textbook that I can go through to understand these molecules and their interactions in a bit more detail? My chemistry is weak and I felt a bit lost. Any help would be greatly appreciated!

Hi there , In my understanding point when we have a solution that contains water as its solvent and we also have Hydrophobics molecule ( for example inside cell we have protein and water ) , Hydrophobics substances ( some proteins) tend to combine with each other as they do they release water molecule ( due to Hydrophobic effect ) , and if we trying to fold protein to the shape which matches with its function our solvent is water so there will be certain too much (Ionic & Hydrogen)bonds which is unnecessary , so due to Hydroponic interaction we are trying to get ride of those unnecessariness ( and as a result we release water ) . Hope u get it

This is absolutely amazing ❤️, she make me feel that molecular component is more a life than me 👀 How I can found text book !

I believe non covalent bonds involved more than just ionic bonds.
