Key Differences

Dextrose, chemically known as D-glucose, is a simple sugar that the body metabolizes quickly for immediate energy. Whereas, sugar typically refers to sucrose, a compound of glucose and fructose, and is metabolized at a slower rate, providing prolonged energy.
Dextrose is often used in medical and sports contexts to rapidly increase sugar levels, while sugar is more common in everyday culinary uses, adding both sweetness and texture to foods. On the other hand, sucrose is the main type of sugar used in baking and sweetening beverages.
Dextrose is less sweet than sucrose, making it less likely to be used for sweetening in culinary contexts, whereas sucrose is preferred for its flavor.
Dextrose is often included in processed foods and emergency treatments as it absorbs quickly into the bloodstream. In contrast, sugar, particularly in its granulated form, is a staple in household pantries and used extensively in cooking and baking across the world.

Sugar

A sweet crystalline or powdered substance, white when pure, consisting of sucrose obtained mainly from sugarcane and sugar beets and used in many foods, drinks, and medicines to improve their taste. Also called table sugar.

Dextrose

A sirupy, or white crystalline, variety of sugar, C6H12O6 (so called from turning the plane of polarization to the right), occurring in many ripe fruits, and also called glucose.
