Campbell's Biology, 9e (Reece et al.) Chapter 5 The Structure and Function of Large Biological Molecules In Chapter 5, the principles of chemistry covered in earlier chapters are applied to the understanding of biological polymers and lipid membranes. The emphasis is on properly linking monomers and their polymers, and on the structural and functional diversity of the different polymer types. Particular attention is given to protein structure, because this is central to understanding subsequent chapters on metabolism, molecular biology, and molecular medicine. Multiple-Choice Questions 1) Humans and mice differ because A) their cells have different small organic molecules. B) their cells make different types of large biological molecules.

Metabolism

Nutrition Notes Foods that are high in calories in unhealthy. - False You should avoid foods with sugars in them. - False You should avoids fats in your diet. - False Vegetarian diets are low in protein. - False Main You rely on energy from food in everything you do. When your body uses the nutrients in foods, a series of chemical reactions occur inside your cells. As a result, energy is released. Metabolism is the chemical process by which your body breaks down food to release energy. A calorie in a unit of measure for the amount of energy released when nutrients are broken down. Nutrients are substances that the body needs to regulate bodily functions, promote growth, repair body tissues, and obtain energy. There are six main nutrients. Carbohydrates Fats Proteins

Carbohydrate chemistry

Glucose

Carbohydrates Robert J Sturgeon, Heriot-Watt University, Edinburgh, UK The carbohydrates comprise one of the major groups of naturally occurring organic molecules and are amongst the most abundant constituents of plants, animals and microorganisms. In general, carbohydrates are polyhydroxy-aldehydes or-ketones. They may contain, in addition, amino, acetamido and carboxyl functional groups. Introduction The term carbohydrate includes monosaccharides, oligo- saccharides and polysaccharides. Also included are sub- stances derived from monosaccharides such as alditols, which are derived by reduction of the carbonyl group and carboxylic acids, which are derived by oxidation of one or more terminal groups. Replacement of a hydroxyl group with a hydrogen atom produces a deoxy-sugar and

Lipids

Lipid

Fat

B io F actsheet April 1999 Number 42 1 The Structure and Function of Lipids All lipids are polymers ? long chains of repeating units joined together in a condensation reaction during which water is released. The commonest lipids are triglycerides ? three fatty acids and glycerol linked by an ester bond (Fig 1). This Factsheet summarises the structure and function of lipids. Lipids are organic compounds found in every type of plant and animal cell. They always contain the elements carbon, hydrogen and oxygen, but the reletive amount of oxygen is less than in carbohydrates. cells in plant roots forces water into the symplast pathway which is under the control of the nucleus. This strip therefore gives the plant control over substances entering the xylem. 7. Buoyancy

Carbohydrates: Revision Summary B io F actsheet January 1999 Number 39 1 Carbohydrates contain 3 elements: Carbon (C), Hydrogen (H) and Oxygen (O). Thus, if we remove water from carbohydrates, all that remains is carbon. Carbohydrates can be divided into 3 categories; monosaccharides, disaccharides and polysaccharides (Table 1). Monosaccharides and Disaccharides Monosaccharides and disaccharides are sugars. They all have the basic formula (CH2O)n and can be classified according to how many carbon atoms they contain. 3C = triose sugars e.g. glyceraldehyde C3H5O2 5C = pentose sugars e.g. ribose C5H10O5 6C = hexose sugars e.g. glucose C6H12O6 Formation of disaccharides - typical exam questions Common exam questions include:

LEVELS OF PROTEIN STRUCTURE Primary Structure?the unique sequence of amino acids, type sequence and number; determines the other three structures It is held together by peptide bonds between the carboxyl group of one amino acid with the amino group of another amino acid B. Secondary Structure? regular repeated coiling and folding of the polypeptide caused by H?bonds between atoms in the polypeptide backbone (a hydrogen on a nitrogen and a double?bonded oxygen atom) see Fig. 5.20 p. 76 a. alpha helix? a delicate coil held together by hydrogen bonding between every fourth peptide bond b. Beta pleated sheet? where regions of the chain lie parallel to each other LEVELS OF PROTEIN STRUCTURE
