Concept introduction: Triacylglycerol is produced by the reaction of one molecule of glycerol and three molecules of fatty acid. The three hydroxyl groups of glycerol get esterified on reaction with fatty acids.
(b)
Interpretation: The number of different kinds of functional groups present in a triacylglycerol in which all fatty acid residues present come from monounsaturated fatty acids has to be predicted.

- Name the following fatty acids by the symbol (C:B)arrow_forwardClassify the fatty acid with the following structural formula in the ways indicated.a. What is the type designation (SFA, MUFA, or PUFA) for this fatty acid? b. On the basis of carbon chain length and degree of unsaturation, what is the numerical shorthand designation for this fatty acid?c. To which “omega” family of fatty acids does this fatty acid belong? d. What is the “delta” designation for the carbon chain double-bond location for this fatty acid?arrow_forwardDraw the skeletal structure of the products formed when the given triacylglycerol is hydrolyzed with water in the presence of sulfuric acid. You may draw the structures in any arrangement that you like, so long as they aren't touching. Oarrow_forward
- Write a balanced equation for the synthesis of a triacylglycerol, starting from glycerol and fatty acids.arrow_forwardIdentify the following fatty acids present in fats and oils by their common names. Which is the most abundant fatty acid? What is the general formula of a saturated fatty acid?arrow_forwarddraw condensed structural formula for monosaturated omega-3 fatty acid with 14 carbon atoms. draw the condensed structural formula for the triacylglycerol made from 3 saturated fatty acids that are 20 carbons longarrow_forward
- Describe the structure of triacylglycerol (TAG) and explain the hydrolysis of TAG.arrow_forwardWrite the structural formula of a triacylglycerol that contains one unit each of lauric acid, palmitic acid, and oleic acid. How many other triacylglycerols, each containing all three of these acids, are possible?arrow_forwardDraw the chemical structure for a phosphatidylethanolamine which contains trans, trans, cis-Δ10, Δ15 Δ18 Eicosatrienoate and cis-Δ13 hexadecenoate fatty acids. What is the omega (w) nomenclature for the two fatty acids in this phosphatidylethanolamine moleculearrow_forward
- Olestra has been used in certain snack foods as an alternative to fats and oils. Its structure consists of a sucrose molecule in which all free hydroxyl groups have formed esters with oleic acid (an 18-carbon monounsaturated fatty acid). Olestra molecules have no caloric value because they are exceptionally large and cannot be digested. Draw the structure of olestra. Use R-COOH as an abbreviation for oleic acid.arrow_forwardDraw the structure of a phosphoacylglycerol that contains glycerol, oleic acid, stearic acid, and choline.arrow_forwardLactic Acid (shown below) is built up in the body during intense workouts as a result of glycolysis. Please denote if the compound is R or S. Also, explain at least two intermolecular forces it would exhibit. Would you expect this compound to be soluble in water?arrow_forward
