[@meroysaleel7069]

thanx a lot شكرا جزيلا

[@varshini8639]

Khan academy is very user friendly academy classes in youtube

[@StudyWithM3E46]

Great video, it was very well aligned with my kaplan 2015 MCAT biochemistry book. Thank you

[@keywordmcat2256]

great, very clear explanation. many thanks!

[@afiaameen8859]

Great explanation! Thank you

[@Jojo-kl6tx]

Thank you a lot! This was actually not as hard as I thought. But I feel like now I'm on solid ground to be able to go on to the more complicated stuff with carbohydrates.

[@zakirhossain9554]

this is really helpful

[@nantashasonia2202]

Thank you

[@jennykonde6189]

Very helpful thank you

[@skashani6]

Great explanation! However, you forgot to mention that 'R'/right stereochemistry notation is often referred to as 'D'. D & L come from the Greek/Latin words for dextro and levo, which mean right and left.

[@pigeonlove]

No, you didn't watch the video 7:15.

[@decentsavage4433]

it has explained

[@peelibhai7058]

man! carbohydrates are not hydrates of carbon...but earlier this waS assume to be but later on various chemical test shows that h2o exist as ketone or aldehyde group... not as hydrate

[@aminimad6715]

You deserve to be instead of my professor and take double the salary.

[@alieucham3391]

Interesting and very easy to understand

[@sciencenerd7639]

very nice

[@zakirhossain9554]

that is awesome

[@gushanana]

So for your glyceraldehyde, would you be looking at carbon 2 to determine D or L?

[@kanadah09]

Yes. Carbon 2 is the only chiral carbon (four distinct chemical groups connected to it) in glyceraldehyde.

[@thebhatmohsin]

Nice

[@tahlilzoman1013]

did you miss a hydrogen on the fructose?

[@smartviews4679]

SIR G MEDICAL ETTA TEST K LIYE KOI HELPFUL NOTES YA KUCH OUR METOD BATHA DA ABI 2ND YAER MAIN HOOOO

[@mattsmith9479]

So with the Fischer projections were you assigning priority to the aldehyde on top or the alcohol on the bottom?

[@GetAFuckinClue]

Cahn-ingold prelog rules

[@ClasssicAri]

this video was all over the place. please make an outline.

[@mattpeters7295]

I thought that a keytone is contained within the carbon skeleton where as an aldehyde is attached to the end of a carbon skeleton?

[@alieucham3391]

That's right

[@HarpreetSingh-gv4lo]

Simple

[@taylormae6617]

This guy has nice hand writing

[@syedfazalhussain1594]

And that's what you took from this?

[@S.Sumedh]

Sir, the fructose is a Pentose ? I guss

[@phantomkiller197]

U mean D not R

[@phantomkiller197]

O nvm just got further

[@allencrider]

Eat carbohydrates, avoid hydrocarbons.

[@yancyaranas5181]

why you did not explain tetrose and pentose? you directly went to hexose. and also you did not much elaborate this topic. i am disappointed, i cannot understand well.

[@GetAFuckinClue]

Why are you even syudying biochem if youre that stupid. Tetrose is a 4 carbon sugar pentose is a 5 carbon sugar. Lmao

[@dallinlayton5923]

Don't be a jerk. It is a common mistake with a lot of people. Some people get it quickly and others need to work at it. Change your attitude.

[@nauhlinuren1499]

He's a jerk because he just said that he can't understand it well? This video is for every student and each student has the right to say that they didn't understand a certain portion. CHANGE YOUR ATTITUDE FIRST SIR

[@lyubomirgizdarski8191]

I think Dallin was talking to Citizen.

[@dallinlayton5923]

Don't leave off the one more Carbon with Fructose as was done in the video. If you count, there are only 5, but he names it a hexose.

[@tahlilzoman1013]

there is a carbon which is double bonded to the oxygen= 6 carbons no?

Its ok but I fucking hate fischer projections. worked for fischer sucks for me

[@scragho5426]

what app is?

[@alieucham3391]

(C.H2O)n

[@lotusflower7597]

i think you mixed fructose with glucose!!!!

[@JasonVaysberg]

Abeer B no he didn’t

[@rainrivo777]

I cant really concentrate because you keep stuttering

[@NIC-og8fr]

Thank you.

[@giardialambia711]

Thank you
