Cholesterol is a steroid that is also a component of cell membranes. A polysaccharide is a lengthy chain of monosaccharides joined by covalent bonds. Predict the color changes you expect to occur in each tube and record them in Table 2 in the Iodine Test Results Expected (color) column. Find the critical points of the following functions on the given interval i.e. Obtain filter paper and on the far edge mark with pencil which solutions will be placed toward the interior of the mark. To log in and use all the features of Khan Academy, please enable JavaScript in your browser. We use many fermentation products--as diverse as antibiotics, alcohols, and a variety of foods. DNA replication supports functions such as cell and tissue growth and maintenance. Lab 6 Week 7 - Food Macromolecules Flashcards | Quizlet Sucrose Molecular Structure from LibreTexts 5.2 Carbohydrates. 4. Nucleotides prevent the body from being damaged by reactive oxygen species (ROS), in addition to enhancing the function of antioxidants. Usually, proteins or steroids, secreted by endocrine glands or groups of endocrine cells that control or regulate specific physiological processes such as growth, development, metabolism, and reproduction. Peptide bonds can be detected by using two chemical reagents, potassium hydroxide (KOH) and copper sulfate (CuSO4). Bromcresol green changes color from pH 3.8 to pH 5.4. can i just say i dont understand any of this lol, https://www.khanacademy.org/science/high-school-biology/hs-molecular-genetics/hs-rna-and-protein-synthesis/v/molecular-structure-of-rna, https://www.khanacademy.org/science/high-school-biology/hs-molecular-genetics/hs-rna-and-protein-synthesis/v/rna-transcription-and-translation, https://www.khanacademy.org/science/high-school-biology/hs-molecular-genetics/hs-rna-and-protein-synthesis/a/hs-rna-and-protein-synthesis-review. One of the tests was for detecting monosaccharides in solution! Messenger RNA is responsible for transcribing the DNA code into a format that can be read and used for protein synthesis. This difference is due to the presence of particular types of bonds within the fatty acid molecule (see figure) and affect the shape and characteristics of the overall lipid containing these fatty acids. Because lipids are nonpolar molecules, they are hydrophobic (water-fearing) and insoluble in water. Add the substances listed in Table 3 to each test tube. Much of the original energy in the substrate remains tin the chemical bonds of organic end products, like lactic acid or ethanol. A precipitating solution means small particles settle out of the solution. Look at the label determine if it does or doesnt. Fatty acids come in two major types, saturated and unsaturated. They can be used for transportation, storage, or membranes. There is a small carbon dioxide bubble in the bottom right area of the tube. To sum it all up: There are 20 chemically different amino acids that form long chains, and the order of the amino acids is arbitrary, so the functions of proteins are very diverse. Direct link to Nicole Gong's post Monomers are the building, Posted 2 years ago. DO NOT allow ethanol to come in contact with the hotplate. However, trans fats cause the following problems in human heart health: B. 2. Look at the label determine if it does or doesnt. Tube 1 (far left) is the uninoculated control. Legal. Introduction to macromolecules (article) | Khan Academy Image by Clarissa Kaup and J. L. Henriksen, Bellevue University, Bellevue, NE. For example, insulin is a protein hormone that maintains blood sugar levels. Tube #SolutionExpected ResultsObserved Results 15mL water 25mL acetonebiochemical tests for food macromolecules. Record the color of each tube in Table 1 in the Benedicts Test Results Observed (color)column. If, for example, you are testing for a type of carbohydrate in unknown solutions, then an appropriate positive control is a solution known to contain that type of carbohydrate. water and lactose. Macronutrient refers specifically to the macromolecules that provide dietary energy to the body. Image 2 : Triple sugar iron (TSI) agar was used to grow and differentiate various bacteria.
