Answer 1

The correct answer is option 4. Dihydroxyacetone.

Glucosamine, N-Acetyl Galactosamine and D-Galacturonic Acid are all derivatives obtained by biochemical synthesis or otherwise. The first two are amino sugars, while D-Galacturonic Acid is a sugar acid and an oxidised form of D-Galactose (also a main component of pectin).

Dihydroxyacetone is a simple saccharide which is also known as Glycerone. It is mainly taken from sugarcane, beets etc.
