Each purine has a corresponding pyrimidine that it can form hydrogen bonds with. There are 5 nitrogenous bases used in nature to create DNA and RNA, which are separated into two groups based on their structure. As additional monomers join by the same process, the chain can get longer and longer and form a polymer. It is revealed that only the cheese did not contain sugar macromolecules, whereas the cracker, cream, yogurt, and raisins did contain sugar macromolecules. Biological macromolecules are organic, meaning they contain carbon. food samples used in this lab, that contain a variety of essential biological macromolecules. 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). elements are bonded to each other within the molecule. The Biuret reagent relies on peptide bonds in proteins, in order to change colour, and has trouble creating a noticeable colour change when it is used in a solution that contains small quantities of peptide bonds in proteins. people maintain a balanced, healthy diet that consists of a variety of the essential biological If it is only stored in certain parts of the body then is it broken down into glucose before it is transported to other cells for use? Each organism must maintain the right balance of fatty acid tails to ensure its cells have functional membranes. Since elephants eat hay, they are getting carbohydrates and proteins to use for energy when the hay is digested. Q1 A positive test for sugars would be when the sample being tested, which contains sugar macromolecules, turns a yellow, orange, brick-red, or green hue, after the Benedicts reagent is added to the sample (Karki, 2018). solution that contains small quantities of peptide bonds in proteins.
