- 27. Which of the following statements correctly describes the structure of a triacylglycerol? Group of answer choices a lipid that makes up much of the plasma membrane a protein with tertiary structure a molecule formed from three alcohols by dehydration reactions a lipid made with three fatty acids and glycerol1. Heat enhances hydrogen bonds, ionic interaction and hydrophobic bonds among the amino residues in a protein.* 1 point The statement is CORRECT. The statement is INCORRECT. 2. Which of the following statements is TRUE for fats and oils?* Fats need more volume of bromine to reach endpoint due to higher degree of unsaturation. Oils need more volume of bromine to reach endpoint due to higher degree of unsaturation. Fats and oils need the same volume to reach endpoint due to same degree of unsaturation. None of the choices1. What is the chemical formula for palmitic acid and oleic acid? Which one is a saturated fat and which one is an unsaturated fat? How do you know? 2. What functional groups are involved in dehydration synthesis reactions to form a triglyceride? What is the waste product? 3. Compare the overall acidity of the molecules before and after the formation of a triglyceride. Proteins 1. What gives each amino R group its key characteristics to make it polar, non-polar, or ionic? 2. What functional groups are involved in dehydration synthesis? 3. How might the solubility of peptides be influenced by the size of the peptides? How might the R group of the amino acid influence it? 4. Would you consider the formation of a peptide bond to be an example of a neutralization reaction? Explain your reasoning.
- 1. Draw the structures of triacylglycerol, cholesterol, phosphatidylcholine, and sphingomyelin. 2. Identify the polar/charged groups and draw how water will orient itself around these groups. 3. Order these lipids from most hydrophobic to most hydrophilic. 4. Predict how the lipids will migrate on the TLC plate when the running buffer is an organic solvent. Keep in mind that although the lipid standards are dissolved in organic solvent, they can (by virtue of their polar/charged groups) interact with the polar silica matrix of the TLC plates.1. Which of the following statements best describe lipids? Lipids are oily or greasy nonpolar O molecules, stored in the adipose tissue of the body. Lipids are a heterogeneous group of O compounds, mainly composed of hydrocarbon chains. Lipids are energy-rich organic O molecules, which provide energy for different life processes. Lipids are a class of compounds characterized by their solubility in nonpolar solvents and insolubility in water. Lipids are significant in biological systems as they form a mechanical O barrier dividing a cell from the external environment known as the cell membrane. O All of the above1. Draw the general structure of glycerophospholipids and designate the site for variation in head group.
