Convert the Haworth projection of the carbohydrate below into its corresponding Fischer projection (in the standard format with

Harlamova29_29 [7]

Answer:

See explaination

Explanation:

H O / I MOH the OH da Anomer My nequatorial bovel SOH niematerial and CH2OH Yr axial boud - H o H o . H (Auro) 2 flip . note: 1)Fischer projection : L- Sugar ( OH group is in the left side ) at C-5 carbon (bottom most chiral center )

In the Haworth projection given above in the qsn it is Beta anomer( -CH2OH & C-OH are in same side i.e. Cis to each other ). It is a L -sugar .

I omitted C2 -H bond (axial ) in the chair conformation of alpha anomer.
