What happens to monosaccharide structures?
the linear and cyclic forms are in equilibrium but the cyclic form is favoured.
1 of 5
what is favoured in water aldehyde or geminal diol?
Aldehyde. Geminal diol is OH-C(-OH)(R)-H
2 of 5
In glucose what number carbon aldehyde forms cyclic.
5, making pyranose as oppose to 4-furanose or 6-septanose form.
3 of 5
which is more stable a/b glucose
b as it avoids clashes with the OH groups.
4 of 5
what is Lobry-de Bruyn-van Ekenstein transformation?
aldehyde to ketone Glucose c=o-cH OH to fructose CH2OH-C=O to manose c=o HO H
