Yes, both starches and glucose are types of carbohydrates.

Carbohydrates are organic compounds made up of carbon, hydrogen, and oxygen atoms. They are one of the main sources of energy for the human body. Starches and glucose are two different forms of carbohydrates.

Starches are complex carbohydrates comprised of long chains of glucose molecules. They are commonly found in foods like potatoes, rice, bread, and pasta. When consumed, starches are broken down by enzymes in our body into simpler glucose units to be used as energy.

On the other hand, glucose is a simple carbohydrate, often referred to as a monosaccharide, which means it cannot be broken down into simpler sugars. Glucose is the primary source of energy for the body's cells and is directly absorbed into the bloodstream after digestion. It can be found in foods like fruits, honey, and some vegetables.

So, to answer your question, starches are a type of complex carbohydrate made up of multiple glucose molecules, and glucose itself is a simple carbohydrate. Both are important sources of energy in our diet.
