When cooh donates a proton it grabs an electron....then coo becomes negative.... "The negative charge can move "it means the electron can move from one oxygen to another oxygen
At 3:40 Isn't a carboxyl group just the carbon double bonded to oxygen? I believe that the group that he's identifying as a carboxyl group is actually a carboxylic acid. Can someone who knows the answer verify?
No he’s right because the portion which he marked is a carboxyl group and if you’re considering the whole the structure then we can name it as carboxylic acid
The dehydration synthesis part makes no sense. Can someone explain why he said that the hydroxyl from the fatty acid grabs a hydrogen proton to form H2O? Wouldn’t it just take the H from the glycerol to form water? Also later on he said that the H left over from the glycerol gets taken from the water molecule to form H2O. Wouldn’t that just form H3O (hydronium ion).

God bless Khan Academy Instructors. You guys are so gifted and help alleviate so much frustration and stress.
Thank you sal. Khan Academy is a lifesaver. I understand so much better compared to an actual class.
What a brilliant teacher. I was absolutely clueless and now it all makes sense!
How could this be such a life saver after all these years 😞
i really need a biology teacher like you
wish you were my professor! THANK YOU :)
Beautiful concept explained fluently
Its 5 years old and still saving me
Thank you very much,
Please explain why triglycerides are bad?
Really well explained. Thanks.
Could anyone further explain 3:40-3:58 please?

Could you increase triglyceride by fasting?
Can anyone tell me how lipid dissolve in organic solvent ?

watching this from online class because of pandemic
Can anyone pls explain how oxygen had positive charge
Nice
Why is it not called tri-ester-glyserol?
Because it’s not only an ester it’s an ester of fatty acid which means three group of fatty acid and glycerol
Why is high triglycerides bad?
How come that the Hydrogen atoms disappear when the glycerol and carbon chain bonds? I talk about the Hydrogen from the glycerol
The other carbon atoms are supposed to be there, I think he missed it out.
sal saves lives.
Hi again HOT VOICE 🥵
My ear is blessed with hearing your voice
This guy tries to cover too much material and can't explain it well, thumbs down
I’m a liberal democrat and I eat whatever I want.
