Question

Why are fatty acids generally composed of an even number of carbons? Why are fatty acids generally composed of an even number of carbons? Fatty acids have an even number of carbons because they are the most stable. Fatty acids have an even number of carbons because they are synthesized in basic media. Fatty acids have an even number of carbons because they are synthesized from a starting material (acetyl-CoACoA) that has an even number of carbons. Fatty acids have an even number of carbons because they are synthesized in acidic media.

Answer 1

Answer:

Fatty acids have an even number of carbons because they are synthesized from a starting material (acetyl-CoACoA) that has an even number of carbons.

Explanation:

Fatty acids are carboxylic acids and are known to have even number of carbon atoms because they are synthesized from a 2 carbon atom acetyl Co-A molecules which are assembled together. It contains a carboxylate group covalently joined with an hydrophobic head of CH3-(CH2)n and may have an unsatireated CH=CH group within its CH2 chain. The synthesis of fatty acids from acetyly Co-A involves the activation reaction of an enzyme acetyl Co-A synthetase with an acid. It involves dehydrogebation, hydration, oxidation and thiolysis. Fatty acids vary in length of its chain, the number of carbon-carbon double bonds attached to its CH2 chain nd also the location of those double bonds in the carbon chain. Saturated fatty acids are those without carbon-carbon double bond in its chain while unsaturated have carbon- carbon double bonds. Monounsaturated fatty acids have one carbon-carbon double bonds and polyunsaturated fatty acids have two or more carbon-carbon double bonds.

Answer 2

Fatty acids are the building blocks of fat molecules. The fat when broken down into simpler forms, yields fatty acids and glycerol.

The correct answer is:

Option C. Fatty acids have an even number of carbons because they are synthesized from a starting material (acetyl-CoACoA) that has an even number of carbons.

The fatty acids are generally even numbers because of the even precursor.

The metabolism of fatty acids starts with the two molecules of the acetyl coenzyme A, which on assembling yields the even-numbered of fatty acids.

The acetyl coenzyme A is an even-numbered two-carbon molecule, which undergoes enzyme-catalyzed reactions to yield an even number of fatty acids.

The even number of fatty acids can be saturated (made up of single bonds) or can be unsaturated (presence of double or triple bonds).

Therefore, Option C is correct.
