Question
The anomeric carbon in $$D(+)$$ glucose is
A.
$$C{\text{ - }}1$$ carbon
B.
$$C{\text{ - 2}}$$ carbon
C.
$$C{\text{ - 5}}$$ carbon
D.
$$C{\text{ - 6}}$$ carbon
Answer :
$$C{\text{ - }}1$$ carbon
Solution :
$$D$$ - glucose exists in two optically active forms known as $$\alpha {\text{ - D - }}$$ glucose and $$\beta {\text{ - D - }}$$ glucose. The two isomers are interconvertible in aqueous solution.
Carbon-1 in both configurations I and II is called an anomeric carbon atom.
