In min 0:52 It isn’t enough to put the last chiral carbon’s alcohol on the left for L-glucose (and other sugars), you have to change all the alcohols to their respective opposite side. If not then you will get a different sugar (an epimer in 2,3,4 of L-glucose, not L-glucose) Same problem for fructose

You should do one where you have to get the methyls on the same plane before converting into a fisher no videos explain this.

sorry,but may i know if the guess and check method,for the up down group,is it ok to put it reversely if I just check the R and S starting from the group corresponding to the 3D structure,for example,I put the CH2OH on the top in the last example, and use the guess and check method and get the fischer projection,is it equivalent to the example one? thank you

@Leah4sciMCAT 25 күн бұрын
If speaking about the Fischer projection (looks like a flat cross molecule), then groups on the horizontal line are coming out of the page, by convention. While groups on the vertical line are going into the page, by convention. For more about Fischer projections, what they mean and how to draw them, make sure to see my free tutorial series at Leah4sci.com/Fischer

I thought zinc is more reactive than copper
@Leah4sciMCAT 25 күн бұрын
Copper has a higher reduction potential than zinc. That means, in reaction with zinc, it will be reduced at the cathode while zinc is oxidized at the anode.

Why did you put H and CH3 in the same plan but they are not
@Leah4sciMCAT 25 күн бұрын
Fischer projections are flat representations of three-dimensional molecules, particularly ones with chiral centers. That means what might look flat is not, in reality, a flat structure. In this short, you'll find me converting a 3-D amino acid into a Fischer. If you'd like to learn more about Fischer projections and how to draw them, I'd suggest starting with my free series at Leah4sci.com/Fischer
