Question

What do all fats have in common?

1) They are acidic.
2) They all have identical hydrocarbon chains.
3) They have a high-energy content.
4) They are all unsaturated molecules.
5) They are all formed from glycerol.
6) all of the above

Answer 1

All fats share a high-energy content and are composed of triglycerides, which consist of glycerol linked to three fatty acids. Fatty acids can be saturated or unsaturated, influencing the fats' physical properties.

Step-by-step explanation:

All fats have in common that they have a high-energy content. Fats and oils are composed of molecules known as triglycerides, which are esters made of three fatty acid chains linked to glycerol. The fatty acids, which are the building blocks of fats, can be saturated or unsaturated. Saturated fatty acids have no carbon-to-carbon double bonds and are usually solid at room temperature, while unsaturated fatty acids contain one or more carbon-to-carbon double bonds and are usually liquids at room temperature.

Fatty acids are long-chain hydrocarbons with a carboxyl group at one end. The length of the carbon chain and the degree of saturation determine the properties of the fatty acid. Therefore, while fatty acids and fats do share some common features, they vary widely in their exact structures and properties.
