hydroxyl group
hydroxyl radical

A carbohydrate is very hydrophillic due to the large number of hydroxyl groups present.

As such, the chemical structures of both are very similar, with the difference existing in the hydroxyl functional group.

Since some of its hydroxyl groups are free the molecule is polar.

Anthracene may also be found with multiple hydroxyl groups, as in 9,10-dihydroxyanthracene.

At carbon 5, all eight aldohexoses have the hydroxyl group on the right.

Wrinkles form in cotton fabrics due to the free hydroxyl groups.

The three hydroxyl groups were modified in the next five reaction steps.

The hydroxyl group in 40 was deprotected to give alcohol 41.

For example, sterols have a hydroxyl group attached at position C-3.

In general, the hydroxyl group makes the alcohol molecule polar.
