Starch and table sugar are both carbohydrates, but they have key differences:
1. **Chemical Structure:**
- Starch is a complex carbohydrate composed of long chains of glucose molecules. It is a polysaccharide.
- Table sugar, also known as sucrose, is a simple carbohydrate made up of one glucose molecule and one fructose molecule bonded together. It is a disaccharide.
2. **Source:**
- Starch is commonly found in plants like grains, potatoes, and corn. It serves as a storage form of energy for plants.
- Table sugar is typically derived from sugarcane or sugar beets and is used as a sweetener in various foods and beverages.
3. **Digestibility and Function:**
- Starch is broken down by enzymes in the body into glucose, which provides a gradual release of energy.
- Table sugar is quickly broken down into glucose and fructose, leading to a rapid spike in blood sugar levels.
4. **Taste and Use:**
- Starch is tasteless and is often used as a thickening agent in cooking.
- Table sugar is sweet in taste and is used to add sweetness to foods and drinks.
In summary, starch is a complex carbohydrate found in plants and provides a sustained release of energy, while table sugar is a simple carbohydrate used as a sweetener that can quickly elevate blood sugar levels.
