Concept explainers
(a)
Interpretation:
The hydrophobic and hydrophilic part of the 7, 10, 13, 16, 19-docosapentaenoic acid should be labeled.
Concept Introduction:
Fatty acids are long chain
Unsaturated fatty acids can be defined as the long chain fatty acids which have a long hydrocarbon chain with −COOH group. In unsaturated fatty acids, the carbon chain must have at least one double bond.
(b)
Interpretation:
The melting point difference in the cis and trans-isomer of the 7, 10, 13, 16, 19-docosapentaenoic acid should be determined.
Concept Introduction:
Fatty acids are long chain carboxylic acid, which may or may not have unsaturation in the molecule. They react with glycerol to form triglycerides. The reaction is known as esterification as a carboxylic acid group reacts with the alcoholic group to form an ester group.
Unsaturated fatty acids can be defined as the long chain fatty acids which have a long hydrocarbon chain with −COOH group. In unsaturated fatty acids, the carbon chain must have at least one double bond.
(c)
Interpretation:
The physical state of 7, 10, 13, 16, 19-docosapentaenoic acid as solid or liquid at room temperature should be determined.
Concept Introduction:

Unsaturated fatty acids can be defined as the long chain fatty acids which have a long hydrocarbon chain with −COOH group. In unsaturated fatty acids, the carbon chain must have at least one double bond.
(d)
Interpretation:
The omega-n designation for the 7, 10, 13, 16, 19-docosapentaenoic acid should be determined.
