12. Carbohydrates/Introduction to Membranes

MIT 7.05 General Biochemistry, Spring 2020
Instructor: Matthew Vander Heiden

In this pre-COVID-19 pandemic lecture of 2020, Professor Vander Heiden discusses two classes of biomolecules: carbohydrates and lipids including their nomenclature, structures, and properties.

This video just shows how one professor can change your opinion on a subject. I hate biochem but this guy made me like it .

I got hooked onto lectures from Robert Sapolsky, his lectures made me really interested to check out other lectures

Thanks for the great lecture, I have a note about the structure of the erythrose.
The L-erythrose structure compared to D-erythrose is wrong on the table ( It's actually the structure of another sugar)

I don't know why YouTube recommended this to me, but I stayed for the whole lecture.,

The main chain formation of Carbosaccharide formation generates a bond break in the entropy which is redundant in the rective chain.
Generates the sum total of turgor pressure in the whole reaction.

I'll be at MIT one day too, wait for me at MIT😃

1:00 "After spring break" well that didn't quite work out diid it

Being has a tendency to 'return' to clusters
='the nature of solidarity' -a desire for empathy -(Wave)-(yin)
and also,
Being has a tendency to 'exist' as individuals
='the nature of self-expension' -a desire for breed-(Particle)-(Yang)

Likewise, humans have two elements.
We must realize that we all have both left and right elements
=Solidarity and Self reliance
No one has only one element.

so 'Sum' derived from 'two poles', (thesis, antithesis, synthesis)
To develop intellect and ethics by harmonizing the two,
It is good to realize it and balance it properly

But A few people polarized the crowd(political partisanship)
without balancing themselves.
And They stole only the sum, only the synthesis from the triangle composition.

Now We all have to get out of this deceptive situation.
This is not the time for us to hate each other.
We have to track down those who have been manipulating us.

a bruised reed he will not break,
and a faintly burning wick he will not quench;
he will faithfully bring forth justice.
He will not grow faint or be discouraged till he has established justice in the earth;
and the coastlands wait for his law.

I like this video so much. If you don't mind, | would like to ask your permission to share this
video to the other website in China for the embarrassing reason that YouTube is blocked from
accessing in China. Of course, | will give sources of the original website. Thank you very much.

At 38:16, it is mentioned how each of the structures are favoured by thermodynamics. Is it possible to shift the equilibrium by introducing an alkaline or acidic solvent to the medium containing the sugar isomers? I can imagine that the hydrogen bonding between these structures will be influenced.

Love to see you guys only cooking with water ;)

Mit is there any course available for organic chemistry basics reaction mechanism

[mimosveta]

too bad so many lectures are missing. .. starting with lecture 12, then jumping to lecture 19?

Interesting, do you know if that membranes have abaility to avoid or stop nanaoparticles to get into body tissues, or do you have somebody in your institution working on something similar? Have a nice day, Best, ❤👍

Did someone forget a hydrogen atom with L-Glyceraldehyde?

mit ocw i beg you please as thirsty student please upload mit 6.045, 6.840, 6.841 6.845 i want to be a theoretical computer scientist but due to less availibility of the in depth knowledge of my professors i am not able to study and make my concepts clear please help ocw . i beg you i want to contribute in the field of computer science that is goal i just want some external help ie your huristic algo will prevent me to want my time and i can finish my understanding basic concept easily. then can reach advance concepts. pls ocw help help help

I am the LORD; that is my name;
my glory I give to no other,
nor my praise to carved idols.

Even if it is a simple definition I DO NOT AGREE at all with the definition given for lipids. As well as I do not agree with the definition of fatty acid. The teacher should try to be much more precise in definitions and chemical structures. Approximations are always negative when talking of science, especially in chemistri. Nomenclature is crucial, and the lack of accuracy in nomeclature is one of the greatest fail in current litterature.
