- 1. Draw the general structure of glycerophospholipids and designate the site for variation in head group. LIPID NAME STRUCTURE Phosphatidic acid Phosphatidylethanolamine Phosphatidylcholine Phosphatidylserine Phosphatidylglycerol Phosphatidyllinositol27. 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. 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.
- 8) Define the following terms: a. Hydrophobic b. Hydrophillic 9) Describe the composition of a phospholipid and its relationship with water. Be specific about how the different parts of a phospholipid interact with water.2. What are the greatest structural features that differentiate sphingolipids from phosphoglycerides?1. Theoretically, a protein could assume a virtually infinite number of configurations and conformations. Suggestseveral features of proteins that drastically limit the actual number. 2. What are the greatest structural features that differentiate sphingolipids from phosphoglycerides? 3. High levels of glucose-6-phosphate inhibit glycolysis. If the concentration of glucose-6-phosphate decreases,activity is restored. Why?

Glycoproteins can be found on the extracellular surface of cell membranes and are used to facilitate cell-cell interactions (connections, identification of cell type, and communication). How does the structure of this molecule allow for its function? How do you think the function of this glycolipid would change if 3 of the lipid was missing? Why?

Show the water molecules made. a) Label the following on the completed phospholipid: hydrophilic and hydrophobic parts of the molecule, fatty acids, phosphate group, and glycerol. b) Compare the structure of the phospholipid to that of a triglyceride. How are the two molecules Similar? How are they different? 2. Use the following vocabulary to label and draw a cell membrane: cytoplasm (cell lumen) extra-cellular fluid hydrophobic hydrophilic polar head non-polar tails a) How many O-H groups are there? And are the O-H areas of sucrose polar or non-polar? b) What is the term that is used to discuss how tightly or loosely an atom's nucleus has a hold of its valence electrons?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 aboveOrganic Molecules and Carbohydrates How many covalent bonds are formed by one carbon, and why? When a double covalent bond is formed, how many electrons are being shared? 3. Given a molecule that was drawn incorrectly, indicate which carbon does not have a sufficient number of bonds. 1. 2. Given a molecular formula (such as CH4) identify the molecule as inorganic or organic. 5. Given an organic molecule (molecular or structural formula) indicate whether the molecule is hydrophobic or hydrophilic and why. 6. Given two molecules, identify whether they are isomers of each other and explain why. 7. Explain the importance of functional groups. Be able to identify and name all functional groups. Define and explain the relationship of the following words: macromolecule, monomer, dimer and polymer. 9. Describe the chemical reactions of dehydration synthesis and hydrolysis in terms of what occurs, and what is accomplished. (Which can bond together monomers? Which splits a dimer or polymer into…
