Question

unsaturated and saturated lipids exhibit different characteristics based on their structures. which characteristic is unique to saturated fats? forms covalent, carbon-to-carbon bonds is a liquid at room temperature contains the maximum number of hydrogen atoms consists of fatty acids and a carboxyl group

Answer 1

The answer is: contains the maximum number of hydrogen atoms.

All lipids consist of fatty acids which contain carboxyl groups (so, choice d. is eliminated). But what makes saturated fats unique is the maximum number of hydrogen atoms. These hydrogen atoms are bonded by Van Der Waals interaction (so, choice a. is eliminated) and therefore saturated fats are solid at room temperature (so, choice b. is eliminated).

Answer 2

Answer:

Maximum number of hydrogen atoms

Explanation:

Saturated lipids have maximum number of hydrogen atoms as possible for the carbon atoms present in them. Unsaturated lipids have double bonds in their structure which reduces the number of hydrogen atoms bonded to the carbon atoms. Absence of any double bond in saturated lipids makes them solid at room temperature.
