(a)

Interpretation Introduction

Interpretation: The structure for $\alpha$-D-Galactose 1-phosphate.has to be drawn.

Concept introduction: The reaction of hydroxyl groups of a monosaccharide with inorganic oxyacids results in the formation of inorganic esters.  Phosphoric acid gives phosphate esters.  Phosphate esters are commonly found in biological systems.
