Concept explainers
To draw:
The skeletal structures of the fatty acids EPA and DHA.
Introduction:
Skeletal structure shows the bonds between the carbon atoms in the form of lines in two dimensions. The bonds between two carbon atoms are indicated by lines. The number of
Fatty acids are the long chain hydrocarbons and a carboxylic acid group is attached at the end of the chain. EPA is a Eicosapentaenoic acid that is found in fish oils. It consists of
DHA is a Docosahexaenoic acid that is also found in fish oils. It consists of

- 21-101 Glycerophospholipids tend to have both a positive charge and a negative charge in their hydrophilic portions. Does this fact help or hinder lipid packing in membranes? Explain.arrow_forward1 Hyaluronic acid acts as a lubricant in the synovial fluid of joints. In rheumatoid arthritis, inflammation breaks hyaluronic acid down to smaller molecules. Under these conditions, what happens to the lubricating power of the synovial fluid?arrow_forward20. Omega-3 fatty acids have which of the following? 1. At least 3 double bonds 2. A 3-carbon backbone 3. A double bond 3 carbons from the end of the chain 4. At least 3 fatty acid molecules linked by omega bondsarrow_forward
- Glucose, C6H12O6, contains an aldehyde group but exist predominantly in the form of the cyclic hemiacetal show below. A cyclic hemiacetal is formed when the —OH group of one carbon bonds to the carbonyl group of another carbon. Identify which carbon provides the —OH group and which provides the —CHO? Give a functional isomer of glucose and draw its structure.arrow_forwardFructose and glucose both contain six carbon atoms. Why do the cyclic forms of fructose have a five-membered ring instead of the six-membered ring found in the cyclic forms of glucose? Draw the skeletal structures.arrow_forwardhow do you draw the skeletal line structure of a 8:0 fatty acid?arrow_forward
- Chain isomers for ascorbic acid ( C8H8O6 )arrow_forwardWhich of the following is saturated fatty acid? Fatty acid A: CH3(CH2)5CH=CH(CH2)7COOH Fatty acid B: CH3(CH2)8COOH Fatty acid C: CH3(CH2)7CH=CH(CH2)7COOH Fatty acid D: CH3(CH2)5CH=CH(CH2)7COOHarrow_forwardDraw the structure of the 1 isomer of C8H18 that contains 4 methyl branches on the main chain.arrow_forward
- 1a. . Isomers are responsible for the diversity of organic compounds. true or false? b. Positional isomers are molecules with different arrangements of the carbon skeleton but with the same chemical formula. true or false? c.)arrow_forwardDraw the structures of the 3 isomers of C8H18 that contain 3 methyl branches on the main chain, 2 of which are on the same carbon.arrow_forwardWhich of the following is not a lipid? A) vitamin D B) triglyceride C) cholesterol D) phenol E) omega-3 fatty acidarrow_forward
