galactose

Popular PHAs are lactobionic acid, gluconolactone and galactose.

There are two common in foods, glucose and fructose; a third, galactose, is derived from more complex sugars.

Like glucose and fructose, galactose seems to promote the production of glycogen in the body.

Galactose occurs in the animal kingdom as one of the constituents of lactose, or milk-sugar.

When hydrolyzed it yields glucose, fructose, and two (or more) molecules of galactose.

These bear the same relation to galactose that the preceding dextrosans do to their constituent hexoses.
