- Module 4-SP2022-SP: Metabol x Take Test: Reading Log Quiz for Ohttps://blackboard.grandview.e.. A Question Completion Status: Fatty acids have an acid on one end (with the elements -COOH) attached to a water-fearing (or v) tail of carbon atoms. If the fatty acid tail has no double bonds, it is referred to as a(n) v fatty acid and is likely to be a solid (fat) at room temperature. If there are one or more double bonds in the fatty acid tail, it is instead a(n) v fatty acid, and is likely to be a liquid (oil) at room tenperature. The double bonds in a fatty acid are normally found in a arrangement, meaning the attached carbons are both on the same side of the double bond. If the carbons are on opposite sides of the double bond, this is a v fat, and is an unhealthy form of fat to be eating.
