Concept explainers
(a)
Interpretation:
General structure for fatty acids, soaps, waxes, and triacylglycerols has to be drawn.
Concept Introduction:
Fatty acid leads to formation of lipid and consists of a carboxyl group
Soap is the long hydrocarbon chain with the metal salt of the fatty acid and is formed by the basic hydrolysis of triacylglycerol.
Waxes are type of nonpolar lipids that contain esters and are formed by the reaction of carboxylic acid with long chain alcohol by the removal of water. Generally, waxes are extracted from plants and animals.
Triacylglycerols are lipids that are formed by two or more similar or different fatty acids. They are also called triglycerides and are hydrophobic and nonpolar in nature. Addition of glycerol and three similar or different fatty acids results into triacylglycerols.
(b)
Interpretation:
Structure of example of fatty acids, soaps, waxes, and triacylglycerols has to be drawn.
Concept Introduction:
Refer to part (a).
(c)
Interpretation:
Whether fatty acids, soaps, waxes, and triacylglycerols are water-soluble or not has to be identified.
Concept Introduction:
Refer to part (a).
(d)
Interpretation:
Whether fatty acids, soaps, waxes, and triacylglycerols are soluble in hexane or not has to be identified.
Concept Introduction:
Refer to part (a).

- 21-100 What are the functions of a cell membrane? To what extent is a bilayer that consists entirely of lipids able to carry out these functions?arrow_forwardFats belong to the class of organic compounds represented by the general formula, RCOOR', where R and R' represent hydrocarbon groups. What is the name of the functional group present in fats? What functional group is common to all saponifiable lipids?arrow_forwardGive numerical answers to the following questions about the structure of a cholesterol molecule. a. How many six-membered rings arc present? b. How many amide linkages are present? c. How many hydroxyl substituents are present? d. How many total functional groups are present?arrow_forward
- The following is a block diagram for a glycerophospholipid where the building blocks are labeled with letters and the linkages between building blocks are labeled with numbers. a. Which building blocks are fatty acid residues? b. Which building blocks are alcohol residues? c. Which linkages are ester linkages? d. Which linkages involve a phosphate residue?arrow_forward1. Draw, using condensed structural formulas, all reactants and products of the saponification reaction of a triacylglycerol using NaOH. Use lauric acid, a 12-carbon saturated fatty acid found in vegetable shortening. 2. Soap can be made using a variety of different fats, oils and bases. Suppose a student wanted to make a soft, liquid soap that lathers easily. What type(s) of fat/oil and base would you recommend? How would this differ from making a solid bar of soap? 3. Vegetable oils are typically liquid at room temperature, yet Crisco (which is made of vegetable oil) is solid at room temperature. Explain why/how this is the case. 4. Explain, with the use of a diagram how soap molecules work to clean “dirt” particles. 5. Amylase is a natural enzyme found in saliva. Describe this enzyme’s function. 6. Lactose is a sugar found in milk and other dairy products. Explain how it is broken down in most individuals. Explain lactose “intolerance”.arrow_forwardwhat are minor constituents of caraway oil and draw structures of it? Ignore all those compounds that typically make up less than 2% of the oil.arrow_forward
- what is the definition of: (a) alkaloids, (b) flavonoids and (c) essential oils Give an example of each of 2 compounds! Write the molecular structure of the common name and IUPAC name!arrow_forwardA simple triacylglycerol is one that: a) Upon hydrolysis produces glycerol and three different fatty acids. b) Upon hydrolysis produces glycerol and at least two different fatty acids. c) Upon saponification gives glycerol and three fatty acid salts. d) Upon saponification gives three esters. e) Upon hydrolysis produces glycerol and three mol of a fatty acid.arrow_forwardExplain why cholesterol, a compound with molecular formula C 27H 46O and one OH group, is soluble in CCl 4 but insoluble in water.arrow_forward
- 1. Explain in 2 sentences how does the definition of “lipid” differ from the types of definitions used for other biological molecules. 2. Draw the structure of a triacylglycerol formed from glycerol, one molecule of stearic acid, and two molecules of oleic acid. The stearic acid should form an ester bond with the 2° OH group of glycerol.arrow_forwardIdentify the functional groups present in THC. Is the molecule likely to be hydrophilic or hydrophobic? Would you expect THC to build up in fatty tissues in the body, or would it be readily eliminated in the urine?arrow_forward2. Draw the skeletal carbon structure of triacylglycerol and highlight the ester linkage.arrow_forward
