Which of the following statements regarding unsaturated fats is true?
all of the aboveExplanation:
Unsaturated fats by definition contain carbon-carbon double bonds in their fatty acid chains. Unsaturated fats have fewer hydrogens per carbon than saturated fats because a double bond replaces two of the hydrogens that would be bonded to the carbons if the fats were saturated. They are also liquid at room temperature because the carbon-carbon double bonds prevent them from forming a densely packed solid.
Saturated fats are saturated with
Saturated fats are solid at room temperature because
the absence of carbon-carbon double bonds in the fatty acid tails allows the tails to fit more compactly together.
What makes a fatty acid an acid?
the −COOH group
What type of molecule (non-ring shaped) is indicated by the molecular formula, C9H15COOH?
an unsaturated fatty acid
Choose the correct answer for the following description: a molecule that contains double bonds between carbon atoms.
unsaturated fatty acids
Most animal fats
lack double bonds.
Triglycerides are lipids that are made up of three
three fatty acids bonded to a glycerol molecule
• Fatty acids that have as many hydrogen atoms as possible on the carbon chain are called
saturated fatty acids
Fatty acids that have double bonds within the carbon chain (and therefore fewer hydrogen atoms) are called
unsaturated fatty acids.
