Question

a monounsaturated fat would have ______. multiple choice one carbon-carbon double bond in a fatty acid tail four carbon rings two carbon-carbon double bonds in its fatty acid tails two fatty acid tails and a phosphate group

Explanation:

To solve this, we recall the definition of monounsaturated fats. Monounsaturated fats have one carbon - carbon double bond in their fatty acid tails.

• Option "four carbon rings" is a characteristic of steroids, not monounsaturated fats.
• Option "two carbon - carbon double bonds in its fatty acid tails" describes polyunsaturated fats.
• Option "two fatty acid tails and a phosphate group" describes phospholipids, not fats.

Answer:

A. one carbon - carbon double bond in a fatty acid tail
