What are the structural differences between a saturated and an unsaturated fat? Carbohydrates, nucleic acids, and proteins can all contain multiple different types of monomers, and their composition and sequence is important to their function. Students are given brief instructions and a sample map to get them started, but they are responsible for determining what details are important in each section. . Explain how polymers are related to monomers. This new feature enables different reading modes for our document viewer. Lets look closer at the structure of a phospholipid. incredibly valuable to know the chemical components of the foods one eats because it can help For instance, several amino acids have charged R-groups. Phospholipids contain polar regions that interact with other polar molecules, such as water, and with nonpolar regions that are often hydrophobic. Double bonds are rigid. why are vitamins not digested in the body. If you're behind a web filter, please make sure that the domains *.kastatic.org and *.kasandbox.org are unblocked. Basic comprehension and critical thinking questions are included in the handout for students to answer as they read the passage. Therefore, we call both a single nucleotide and many nucleotides connected together a nucleic acid.. The double-helix also allows for repair proteins to easily find errors. There are four major classes of biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids), and each is an important component of the cell and performs a wide array of functions. As additional monomers join by the same process, the chain can get longer and longer and form a polymer. Like a carbohydrate bonded to a protein? This is called transcription. These indicators were also used in testing five food samples for the previously mentioned macromolecules. The scope of this module permits it to be used in many different learning situations. mostly made of? Therefore, you can pack many saturated fatty acids into a very tight space. people maintain a balanced, healthy diet that consists of a variety of the essential biological Biomacromolecules are biomolecules which have a large size of 800 to 1000 daltons, high molecular weights and complex structures. Each organism must maintain the right balance of fatty acid tails to ensure its cells have functional membranes. Is that even possible? it can be evaluated.
