Concept explainers
Interpretation:
The product formed from the hydrogenation of the triacylglycerol has to be drawn, its name should be given and its melting point has to be compared with the original triacylglycerol.
Concept introduction:
Hydrogenation:
Hydrogenation is the addition of hydrogen molecules to the unsaturated carbon-carbon double bond which makes them saturated and solidified.
Melting point:
Based on the saturation and unsaturation of a compound, the melting point varies. For unsaturated compounds, the intermolecular attractions are weaker than the saturated compounds and so the melting point of unsaturated compounds will be lower than saturated compounds.

- Write 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_forwardIn the formula for sucrose (structure shown above), the bottom ring is pyranose. True or False?arrow_forwardDraw condensed structural formulas for all products obtained from the complete hydrolysis of the following triacylglycerol.arrow_forward
- Spermaceti, a fragrant substance isolated from sperm whales, was commonly used in cosmetics until it was banned in 1976 to protect the whales from extinction. Chemically, spermaceti is cetyl palmitate, the ester of palmiticacid with cetyl alcohol (the straight-chain 16-carbon alcohol). Draw the structure of spermaceti.arrow_forwardD- and L- designations are used to distinguish between the two possible enantiomers of the monosaccharide, galactose. From the Fischer projection, determine the designation of this monosaccharide.arrow_forwardWhich form of aspartic acid in Problem 18.54 is the zwitterion? What is the pI for the zwitterion?arrow_forward
- Draw the skeletal structure of the products formed when the given triacylglycerol is hydrolyzed with water in the presence of sodium hydroxide. You may draw the structures in any arrangement that you like, so long as they aren't touching.arrow_forwardIn the monosaccharide derivatives known as sugar alcohols, the carbonyl oxygen is reduced to a hydroxyl group. For example, D-glyceraldehyde can be reduced to glycerol. However, this sugar alcohol is no longer designated D or L. Why?arrow_forwardSorbitol is a sweetener often substituted for cane sugar, because it is better tolerated by diabetics. It is also an intermediate in the commercial synthesis of vitamin C. Sorbitol is prepared by high-pressure hydrogenation of glucose over a nickel catalyst. What is the structure (including stereochemistry) of sorbitol?arrow_forward
- What is the structure of a simple triaclyglycerol from compound J and Harrow_forwardFor the first part, draw a Fischer projection formula for the enantiomer of each of the following monosaccharides. For the second part, identify whether the images are in D- or L-configuration. Write your answers first on a piece of bond paper.arrow_forwardThe pk, values for the carboxy and ammonium protons of phenylalanine are 2.58 and 9.24, respectively. What is the isoelectric point of phenylalanine? Draw the structure of phenylalanine at its isoelectric point.arrow_forward
