Lecture Presentations byNicole Tunbridge and Kathleen Fitzpatrick Chapter 5The Structure and Function of Large Biological Molecules 1 The Molecules of Life All living things are made up of four classes of large biological molecules: carbohydrates, lipids, proteins, and nucleic acids Macromolecules are large molecules and are complex Large biological molecules have unique properties that arise from the orderly arrangement of their atoms ? 2017 Pearson Education, Inc. Concept 5.1: Macromolecules are polymers, built from monomers A polymer is a long molecule consisting of many similar building blocks The repeating units that serve as building blocks are called monomers Carbohydrates, proteins, and nucleic acids are polymers ? 2017 Pearson Education, Inc.

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

Chemical Components of Cells Part II- Protiens 1.19.16 Proteins are composed of amino acids General structure of an amino acid where R is one of twenty different side chains At pH=7, both the carboxyl and amino groups are polarized In cell, cytosol will always make it ionized Amino acids are linked together by peptide bonds R Groups have different chemical properties: Be able to decide if each R-group is hydrophobic or hydrophilic Proteins are folded polymers of amino acids Primary - linear Secondary - alpha or beta Tertiary - combination of alpha and beta, globular Quaternary - combination of globular structures Folding of protein determines function Most proteins adopt a single highly preferred conformation

Chapter 5: The Structure and Function of Large Biological Molecules Outline The Molecules of Life Macromolecules: carbohydrates, proteins, and nucleic acids Architecture of a large biological molecule helps explain how that molecule works Macromolecules are Polymers, Built from Monomers Polymer: A long molecule consisting of many similar or identical building blocks linked by covalent bonds, much as a train consists of a chain of cars Monomers: The repeating units that serve as the building blocks of a polymer Synthesis and Breakdown of Polymers Enzymes: Specialized macromolecules that speed up chemical reactions Dehyrdration Reaction: Two molecules are covalently bonded to each other, with the loss of a water molecule
