so a hemiketal, acteal, or hemiacteal are all reducing sugar but a ketal isnt?

acetal is not a reducing sugar.

reducing sugars are thoses that can be oxidized to an acid. therefore aldehydes sugars (aldose) and their ring form (hemiacetals) are reducing sugars. ketone sugars (ketose) can also be a reducing agent because of ketoenol tautomerisation.

so only hemiketal and hemiacteal?

 

[userah]

yup, just the two =)
