Fatty acids only
Fatty acids, cholesterol, and ketone bodies can be made from acetyl CoA molecules.
A fatty acid that contains 20 carbons will yield 10 molecules of acetyl-CoA. Acetyl-CoA is also referred to as acetyl coenzyme A.
The coenzyme that transports organic molecules into the citric acid cycle is coenzyme A (CoA). It acts by forming a thioester bond with acetyl groups derived from organic molecules, allowing them to enter the cycle for energy production.
Acetyl-CoA is a common molecule generated during the breakdown (catabolism) of both fat and glucose. Acetyl-CoA is a key intermediate that enters the citric acid cycle to generate energy through the production of ATP.
Acetyl Co-A
Fatty acids are converted into acetyl-CoA molecules during beta-oxidation. Acetyl-CoA is a crucial molecule in the citric acid cycle (Krebs cycle) which generates energy through the production of ATP.

Acetyl Co-A
The two molecules that enter the citric acid cycle are acetyl-CoA and oxaloacetate. Acetyl-CoA is the key input that combines with oxaloacetate to initiate the cycle.
Acetyl CoA
Acetyl CoA is multifunctional; it can be used to produce fat or ATP. If the body needs energy, acetyl CoA enters the Krebs cycle. If the body doesn't need energy, acetyl CoA is channelled into an anabolic pathway that synthesizes lipids as a way of storing large amounts of energy as fat.
Acetyl coenzyme A is produced twice from one molecule of glucose in the process of glycolysis and the citric acid cycle. Each glucose molecule is broken down into two molecules of pyruvate during glycolysis, and each pyruvate molecule is converted to one molecule of acetyl CoA before entering the citric acid cycle.
Cholesterol synthesis from acetyl CoA molecules
The Krebs cycle primarily generates ATP, carbon dioxide, and reduced electron carriers NADH and FADH2. These molecules are essential for energy production in the mitochondria.
