Science 319, 20 (2008). Wright, L. Looking deep, deep into your genes. Sports players use steroids to strengthen their muscles. In other words, carbon atoms are the perfect building blocks for large organic molecules. This short quiz doesnotcount toward your grade in the class, and you can retake it an unlimited number of times. These reactions are similar for most macromolecules, but each monomer and polymer reaction is specific for its class. As we shall see, there are four gen-##### eral types of macromolecules, the basic chemical building ##### blocks from which all organisms are assembled. Biological macromolecules are organic, meaning they contain carbon. Explain at least three functions that lipids serve in plants and/or animals. There is great diversity in the manner by which monomers can combine to form polymers. Start your lesson off with this exploratory video! Proteins are a class of macromolecules that can perform a diverse range of functions for the cell. Pictured is an enzyme responsible for releasing energy from sugar. It covers the atoms that are building blocks for proteins and how their shape impacts their function. Each card gives students an activity to promote active learning. Fats and oils are a stored form of energy and can include triglycerides. The first analyses of samples brought back from the asteroid Ryugu show that this space rock contains some of the molecules needed for life. Even one kind of monomer can combine in a variety of ways to form several different polymers: for example, glucose monomers are the constituents of starch, glycogen, and cellulose. Unlike the genome and proteome, the glycome and lipidome are not directly encoded by DNA. All life is composed mainly of the four macromolecule building blocks: carbohydrates, lipids, proteins, and nucleic acids. An analysis of a tiny portion of this sample revealed that the carbon-rich asteroid also contains molecules that are crucial to all known life, including 15 amino acids, the building blocks of proteins. Keep your students stay organized with this simple graphic organizer. The monomers combine with each other via covalent bonds to form larger molecules known as polymers. This five-minute video takes your students on a nutritional journey to understanding amino acids and proteins.

Students simply click and drag the terms into the correct box. Make a list of key terms and glue it to one side of the folder. Three of the four major classes of biological macromolecules (complex carbohydrates, nucleic acids, and proteins), are composed of monomers that join together via dehydration synthesis reactions. All life is composed mainly of the four macromolecule building blocks: carbohydrates, lipids, proteins, and nucleic acids. While they have different structures and functions, they are all composed of long complex chains of molecules (polymers) made up of simpler, smaller subunits (monomers). They help in metabolism by providing structural support and by acting as enzymes, carriers or as hormones. There are four types: Lipid, proteins, carbohydrates, and nucleic acids Slide 3 B. PubMedGoogle Scholar, Marth, J. Defining the molecular building blocks of life provides a conceptual framework for biology that has the potential to enhance education and research by promoting the integration of knowledge. Each protein or nucleic acid with a different sequence is a different molecule with different properties. Simply gargle some salt water and take a swab from your cheek. These asteroids are essentially the scraps left behind when the solar system formed, making them an intriguing window into the molecules present some 4.5 billion years ago. As weve learned, there are four major classes of biological macromolecules: Lets take a closer look at the differences between the difference classes. Use any candy to represent atoms: marshmallows, candy dots, and chocolate kisses all work. Monomers are the building blocks of the four basic macromolecules of life- monosaccharides are the monomers of carbohydrates, amino acids are the monomers of proteins, glycerol/fatty acids are the monomers of lipids, and nucleotides are the monomers of DNA. Youll need some liver, hydrogen peroxide, and some test tubes. In the meantime, to ensure continued support, we are displaying the site without styles Carbohydrates are classified as monosaccharides, disaccharides, and polysaccharides, depending on the number of monomers in the molecule. Figure 1. Carbohydrates. Therefore, carbon atoms can form four covalent bonds with other atoms to satisfy the octet rule.
