👉 Starches are a type of carbohydrate that is found in plants, particularly legumes and grains. They are composed of a complex mixture of sugars such as glucose (C6H12O6), fructose (C6H12O6) and galactose (C18H34O). These sugars are linked together in chains to form long chains that are found in the cell walls of plants. Starches are essential for the growth, survival and energy production
