Carbohydrates

Made from atoms of carbon (C), hydrogen (H) and oxygen (O) Made from atoms of carbon (C), hydrogen (H) and oxygen (O) Examples are starch, glycogen (stored form of glucose) and sugars Examples are starch, glycogen (stored form of glucose) and sugars Carbohydrates are the body’s primary source of energy. Carbohydrates are the body’s primary source of energy.

Carbohydrates are produced in nature by plants in a process called Photosynthesis Carbohydrates are broken down in the body in a process called Cellular Respiration

Types of Sugars Monosaccharides (simple sugars) = glucose, fructose and galactose Monosaccharides (simple sugars) = glucose, fructose and galactose

Types of Sugars Disaccharides (2 monosaccharides bound together) = Sucrose and lactose Disaccharides (2 monosaccharides bound together) = Sucrose and lactose Sugar CaneSugar Beets

Types of Sugars Polysaccharides (Complex carbohydrates) = starch, cellulose, and glycogen Polysaccharides (Complex carbohydrates) = starch, cellulose, and glycogen Animal starch Plant support Storage molecules for plants
