Document Summary
Are composed of 3 or more monosaccharides linked together. Broken down into individual monosaccharides: starch. Plants store glucose as polysaccharides in the form of starch. Grains (wheat, rice, corn), legumes (peas, beans, lentils), and tubers (potatoes and yams) Our body must break starch molecules down into the monosaccharide glucose (can be used to fuel our energy needs) Photosynthesis enables plants to capture energy from the sun. Non digestible part of plants that form leaves, stems, and seeds. Long polysaccharide chains, not easily broken down and absorbed (unlike starches) Contributed little or no energy to our diet. Diverse groups of polysaccharides found in plants. Support structure of leaves, stems, and plants. Reduces the risk of coronary artery disease. Reduces risk for gastrointestinal diseases and heart disease. Better control of blood glucose and cholesterol levels. Storage form of glucose in all animals (including humans) We can break it down very quickly when we need it for energy.
