Macromolecules are giant organic molecules that fall into four categories: Carbohydrates, Lipids, Proteins, and Nucleic Acids. The four main macromolecules are carbohydrates, proteins, nucleic acids (DNA/RNA), and lipids. ESSENTIAL KNOWLEDGE SYI-1.B.2 Structure and function of polymers are derived from the way their monomers … Flashcards. Polysaccharides play important roles in cells such as energy storage (animal glycogen) and structure support (plant cellulose). Starch, glycogen and cellulose are also examples of polysaccharides. Biological membranes have a double layer of lipids which are amphipathic in nature. In comparison to nucleotides or amino acids they are chemically simpler, containing just the three elements of carbon, hydrogen, and oxygen. There are four major classes of biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids); each is an important cell component and performs a wide array of functions. Monomers . Macromolecules are formed by dehydration reactions in which water molecules are removed from the formation of bonds. Terms like dimer(twounit molecule) and trimer(threeunit molecule) are also used. A very large molecule made up of smaller units called monomers. Proteins are made of C, H, O, N and S.  The building units of proteins are amino acids. © copyright 2003-2020 Study.com. This concludes our consideration of the relationship between the structures of biological polymers and their monomer subunits. There are numerous types of each macromolecule. Types of large biological molecules. DNA. Each nucleotide has three basic parts: a nitrogenous base, phosphate group and a sugar. They are proteins, carbohydrates, nucleic acids and lipids. Fill in the table below: Table 1: Classes of macromolecules and their properties. polymer: A relatively large molecule consisting of a chain or network of many identical or similar monomers chemically bonded to each other. If the necklace is the polymer, what are the monomers that make up the necklace? Four (bio)macromolecules are: Carbohydrates (e.g. There are numerous types of each macromolecule. • Pentose sugar (deoxyribose or ribose) There are three types of carbohydrates, monosaccharides contain one sugar, disaccharides contain two sugars, and polysaccharides contain many sugars. 3 Answers. Answer Save. Both monomers are from certain types of acids. Biological macromolecules are large molecules, necessary for life, that are built from smaller organic molecules. 4 major classes of biological molecules include: Carbohydrates (monosaccharides, oligosaccharides, polysaccharides) Lipids (triglycerides, phospholipids, steroids) Carbs also contains carbon, oxygen, and hydrogen like lipids and proteins do. 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. Function. You will be introduce to the macromolecules and their monomers; The 4 Macromolecules are: 1) Carbohydrates ( Polysaccharides) - monomers; glucose 2) Proteins - monomers; amino acids 3) Lipids - monomers; fatty acids and glycerol 4) Nucleic acids - monomers; nucleotides.
