Common Name

Galactitol

Class

Small Molecule

Description

Galactitol is a naturally occurring product of plants obtained following reduction of galactose. It appears as a white crystalline powder with a slight sweet taste. It may form in excess in the lens of the eye in galactosemias a deficiency of galactokinase.

Toxicity Profile

Route of Exposure

Not Available

Mechanism of Toxicity

Accumulation of galactitol in the body has been shown to be toxic. Accumulation of galactitol in the lens causes the osmotic phenomena and results in cataract formation. It may form in excess in the lens of the eye in galactosemias, a deficiency of galactokinase.

Metabolism

Not Available

Toxicity Values

Not Available

Lethal Dose

Not Available

Carcinogenicity (IARC Classification)

No indication of carcinogenicity to humans (not listed by IARC).

Uses/Sources

This is an endogenously produced metabolite found in the human body. It is used in metabolic reactions, catabolic reactions or waste generation.

Minimum Risk Level

Not Available

Health Effects

Chronically high levels of galactitol are associated with at least 2 inborn errors of metabolism including: Galactosemia and Galactosemia type II.
