Concept explainers
(a)
Interpretation:
Anomer of the aldohexose should be converted to its Haworth projection.
Concept Introduction:
Haworth formula indicates the connectivity of atoms in a ring structure. The linear structure should be used in the conversion.
(b)
Interpretation:
Anomer of the aldohexose should be converted to its Haworth projection.
Concept Introduction:
Haworth formula indicates the connectivity of atoms in a ring structure. The linear structure should be used in the conversion.
(c)
Interpretation:
Anomer of the aldohexose should be converted to its Haworth projection.
Concept Introduction:
