Question
Chapter 22, Problem 40E
Interpretation Introduction
Interpretation:
The reason as to why the human body contains only fatty acids with an even number of carbon atoms is to be stated.
Concept introduction:
Lipids are organic compounds, which are fatty acids or the derivatives of fatty acids. They are insoluble in water but are soluble in non-polar organic solvents. They include natural oils, waxes, and steroids.

Students have asked these similar questions
Why does butter stay solid at room temperature, while olive oil remains as a liquid? Explain your answer in the context of the molecular structure of the lipids composing these two substances.
Unsaturated fats_
have double bonds in the carbon chains of their fatty acids.
are more common in animals than in plants.
have fewer fatty acid molecules per fat molecule.
O contain more hydrogen than do saturated fats having the same number of carbon atoms.
generally solidify at room temperature.
The monomers of lipids are called fatty acids. Draw the lipid monomer a fatty acid, labeling the hydrocarbon chain and the carboxyl end group. Be sure to show ALL of the atoms within the molecule (there are several different fatty acids in living things including oleic acid and stearic acid, each with a unique molecular formula).

- As low carbohydrate diets have had a dramatic popularity increase in the past decade, arguments have been made that glucose can be made from odd- chain fatty acids. Based on the metabolism of such molecules, what quantity of a C-19 fatty acid would be required to produce 1 g of glucose? Consider- ing that odd-chain fatty acids make up approximately 1% of the fat in our diet, what quantity of fatty acids would be needed to produce 1 g of glucose?arrow_forwardIndicate whether or not each of the following statements is TRUE or FALSE. Justify your answer with ONE or TWO sentences. i. Lipids are considered to be more soluble in water than in other solvents. ii. The many -OH groups present in carbohydrates such as glucose make them quite insoluble in water and blood. ii. Carbohydrate structure shows that water molecules are connected to carbon atoms. iv. Hydrocarbons contain carbon, hydrogen and oxygen. A monosaccharide can be hydrolyzed to smaller units. V.arrow_forward3. The metal cations present in "hard" water can decrease the cleansing power of soaps. This is because the calcium, magnesium, and iron III metal cations form insoluble precipitates with fatty acid carboxylate anions.
