Step-by-step explanation:
Sorbitol (glucitol) is a type of sugar alcohol that human body metabolizes very slowly.
It can be obtained by the reduction of the glucose in which the aldehyde group is converted to a hydroxyl group.
If too much sorbitol is trapped in the cells of the lens, it can lead to cataracts, retinopathy and peripheral neuropathy.
The open chain structure of sorbitol is shown in the image below.
