Chapter 23 ? 2010, Prentice Hall Organic Chemistry, 7th Edition L. G. Wade, Jr. Carbohydrates and Nucleic Acids Chapter 23 * Carbohydrates Synthesized by plants using sunlight to convert CO2 and H2O to glucose and O2. Polymers include starch and cellulose. Starch is a storage unit for solar energy. Most sugars have formula Cn(H2O)n, ?hydrate of carbon.? Chapter 23 Chapter 23 * Classification of Carbohydrates Monosaccharides or simple sugars: polyhydroxyaldehydes or aldoses polyhydroxyketones or ketoses Disaccharides can be hydrolyzed to two monosaccharides. Polysaccharides hydrolyze to many monosaccharide units. For example, starch and cellulose have > 1000 glucose units. Chapter 23 Chapter 23 * Monosaccharides Classified using three criteria:

Chemical Components of Cells - Part I: Sugars 1/14 Living organisms are chemical systems Cells contain relatively few elements The distribution of elements differs dramatically from living organisms to inanimate matter Mostly carbon, nitrogen, oxygen, and hydrogen Why do living organisms contain so much hydrogen and oxygen? Water is the most abundant molecule in the cell Atoms can interact with each other through covalent and non-covalent bonds MOLECULES ARE COVALENTLY BONDED ATOMS Result from the sharing of electrons & form the backbone of molecules Strong molecular bonds that require energy to make and break The number of electrons in the outer shell determine reactivity* Not always shared equally (i.e. Polar vs non-polar molecules)

Biology Top Ten Elizabeth Kim Natural selection acts on individuals; evolution acts on populations. Water?s polarity contributes to its properties of cohesion and adhesion. Functional groups determine a molecule?s properties ? acidity, baseness. Active transport requires input of free energy while passive transport does not. Each enzyme has a specific function due to distinct shapes of active sites and the substrates that fit into it. Protein is formed from polypeptide chains of their monomers ? amino acids. In early life, as organisms became exposed to a new environment with oxygen, they were able to use photosynthesis to acquire and use energy more efficiently for gaining resources.

APES ID: Chapter 12 ? Food, Soil, and Pest Management Distinguish between chronic under-nutrition (hunger) and chronic malnutrition. People who cannot grow or buy enough food to support their basic energy needs suffer from chronic under-nutrition or hunger. Chronic malnutrition is caused by protein and key nutrient deficiency. What 3 systems provide most of the world?s food? Distinguish among the following types of agriculture: croplands, rangelands, and oceanic fisheries industrialized agriculture- high input agriculture, using heavy equipment and large amounts of financial capital, fossil fuel, water and commercial fertilizers and pesticides to produce single crops or monocultures.

S. H. Short, Ph.D.,Ed.D.,R.D. Prof of Nutrition, Syracuse University FIBER Fiber is found ONLY IN PLANTS. 1. Definition ? Fiber is a combination of substances, some of which are carbohydrates, and most of which are not digested by humans. Dietary fibers are classified as water?soluble or water?insoluble. Water?INSOLUBLE fiber (more likely to reduce constipation) is in foods such as wheat bran cereals, wheat products, brown rice, cooked lentils. Water?SOLUBLE fiber (more likely to reduce blood cholesterol) is in foods such as apples, bananas, citrus fruit, carrots, oats. Some foods contain both types of fiber such as kidney beans, navy beans, green beans, green peas.

Chapter 7 Vitamins The Nature of Vitamins A. Definition - Vitamins are organic substances needed by the body in small amounts for normal metabolism, growth and maintenance - Coenzymes are substances that activate enzymes - do not provide energy B. Classification - major distinguishing characteristic of vitamins are their solubility in either fat or water - measured in micrograms C. Fat Soluble Vitamins - are absorbed from the intestine in the same way as fats, and like fats they can be stored in the same way - A, D, E, K - toxicity from vitamin A and D can be fatal D. Water Soluble Vitamins - B vitamins and C ? less stable to environmental influences; only B12 stored for any length of time Vitamin A A. Forms - necessary for vision
