Thank your for the clear tutorial ! please correct me if i'm wrong. when you say [05:30] : when i draw Alpha, it (OH) goes down, and Beta, it goes Up. this work only for D-glucose, for L-glucose it's the opposite. the position of your OH on the first carbon depends on the position of the carbon 5. if you want an alpha, then put your carbon's 1 OH at the same side of the carbon's 5 OH if you want a Beta, then put your carbon's 1's OH at the opposite side of the carbon's 5 OH

This was so helpful! One question: If the carbons are numbered by priority for the D glucose molecule, how come for the D furanose carbon 2 is doubled bonded to an oxygen? Wouldn't that be highest priority?

@Leah4sciMCAT 3 месяца назад

The chain is numbered from the direction of the carbonyl, however the end of the chain still gets a number 1 making the carbonyl the lowest possible number on the chain (in this case #2 rather than #5)

@abhijeetbaliga5198 7 лет назад

How to recognize if a compound is D or L by looking at the Haworth projection?

@lenaalsaleem3769 7 лет назад

abhijeet baliga If the CH2OH is up then it's a D-sugar, if it's down it will be a L-sugar. But most sugars in nature are D-sugars.

@progress360infra5 6 лет назад

thanks to both of you

@alaataha1558 6 лет назад

Note that when when assigning alpha or beta it dependent on the CH2OH too, meaning if the hydroxyl on the anomeric carbon points in the same direction as the CH2OH its a beta (since most sugars are D we kind off generalize and say up is beta but just watch out for that.)

@Leah4sciMCAT 6 месяцев назад

Take a look at what happens to that specific carbon and OH group when converting from Fischer to a ring. Notice that on D the CH2OH points up, while on L it points down

@roadallowance 6 лет назад

The definition of an alpha anomer is that in the Fisher projection the OH at C1 is on the same side as the OH that defines the structure as D or L. The beta anomer is the opposite - in any sugar. This is when the ring is drawn to continue to the backbone up from C1. Also, the name Haworth is pronounced with a short a sound (not Hayworth).
