The answer to the above question is Fatty acids.
<h3>What are
Fatty acids?</h3>
A fatty acid is a carboxylic acid with an aliphatic chain that is either saturated or unsaturated. This definition applies to chemistry, particularly biochemistry. The majority of naturally occurring fatty acids have an unbranched chain with 4 to 28 carbon atoms, which is an even number. In some species, like microalgae, fatty acids make up a significant portion of the lipids (up to 70% by weight), but in other organisms, they are present as one of the three main types of esters: triglycerides, phospholipids, or cholesteryl esters rather than in their solo form. Fatty acids are crucial nutritional sources of energy for animals in any of these forms, as well as crucial cellular building blocks.
