Textbook Question
Chapter 3, Problem 3.58P
The composition of a cell membrane is not uniform for all types of cells. Some cell
membranes are more rigid than others. Rigidity is determined by a variety of factors, one of which is the structure of the carbon chains in the phospholipids that comprise the membrane. One example of a phospholipid was drawn in section 3.7A, and another, having C-C bonds in its carbon chain, is drawn here. Which phospholipid would be present in the more rigid cell membrane and why?

- Formaldehyde, H2C=O, is known to all biologists because of its usefulness as a tissue preservative. When pure, formaldehyde trimerizes to give trioxane, C3H6O3, which, surprisingly enough, has no carbonyl groups. Only one monobromo derivative (C3H5BrO3) of trioxane is possible. Propose a structure for trioxane.arrow_forwardDimethylamine, (CH3)2NH, has a molecular weight of 45 and a boiling point of 7.4 °C.Trimethylamine, (CH3)3N, has a higher molecular weight (59) but a lower boiling point(3.5 °C). Explain this apparent discrepancyarrow_forwardThe disinfection of drinking water to control microbial contaminants can form chemical disinfection byproducts. These compounds result from the reaction of chlorine with naturally occurring organic matter (the dissolved molecules that give natural water the yellow-greenish color). One class of disinfection byproducts is the malodorous and unpalatable chlorophenols. 2,4-dichlorophenol is one compound of this class. a) Calculate the vapor pressure p*L of 2,4-dichlorophenol at 60 °C using Tb and structural information only OH .CI M, = 163.0 g/mol Tm = 43.7 °C Tp = 213.0°C %3D %3D %3Darrow_forward
- By saponification of plant material and subsequent acidification, petroselenic acid (C18:1Δ6), which was forming a triglyceride, is extracted. Mark the INCORRECT option: a) The petroselenic acid was part of a vegetable oil. b) Petroselenic acid is classified as ω6. c) Petroselenic acid has a double bond between C6 and C7. d) The oil from which the petroselenic acid was extracted is liquid due to its unsaturation. e) The saponification of said oil produces a salt of petroselenic acid (soap).arrow_forward11. If in lab you run out of dichloromethane (CH₂Cl₂), but you have carbon tetra- chloride (CC14) and acetone (C3H6O), would you predict that either, neither or both work to achieve this lipid extraction from water? Draw the Lewis struc- tures and use molecular shape, molecular polarity and intermolecular forces between (including between solvent and water) in your explanation.arrow_forwardWhen A (an organic compund having a molecular formula of C8H16) was poured in water and heated, C8H18O was formed.

- Glutathione is a tripeptide whose function is to destroy harmful oxidizing agents in the body. Oxidizing agents are thought to be responsible for some of the effects of aging and to play a causative role in cancer. Glutathione removes oxidizing agents by reducing them. In the process, glutathione is oxidized, resulting in the formation of a disulfide bond between two glutathione molecules. An enzyme subsequently reduces the disulfide bond, returning glutathione to its original condition so it can react with another oxidizing agent.a. What amino acids make up glutathione? b. What is unusual about glutathione’s structure?arrow_forwardAdenine and guanine are the members of a class of molecules known as purines; they have two rings in their structure. Thymine and cytosine, on the other hand, are pyrimidines and have only one ring in their structure. Predict which have larger dispersion forces in aqueous solution.arrow_forwardThe cleaning ability of soap is based on its structure. Which structures represent compounds that can be used as soaps? are the following Soap or Not a Soap.arrow_forward
- Which statements accurately describe soap? Select one or more: Soaps are a mixture of fatty acid salts and glycerol. Soaps react with ions in hard water to create a precipitate. Soaps should be weakly alkaline in solution. aps work in solutions of any pH. Soaps are both hydrophobic and hydrophilic.arrow_forwardAlkaloids are basic nitrogen-containing compounds of plant origin, many of which are physiologically active when administered to humans. Ingestion of coniine, isolated from water hemlock, can cause weakness, labored respiration, paralysis, and eventually death. Coniine is the toxic substance in the “poison hemlock” used in the death of Socrates. In small doses, nicotine is an addictive stimulant. In larger doses, it causes depression, nausea, and vomiting. In still larger doses, it is a deadly poison. Solutions of nicotine in water are used as insecticides. Cocaine is a central nervous system stimulant obtained from the leaves of the coca plant.Classify each amino group in these alkaloids according to type (primary, secondary, tertiary, aliphatic, aromatic, heterocyclic).arrow_forwardIndicate whether each statement is true or false: Fat molecules contain amide bonds. Phospholipids can be zwitterions. Phospholipids form bilayers in water in order to have their long hydrophobic tails interact favourably with each other, leaving their polar heads to the aqueous environment.arrow_forward
