Beta-oxidation is the major pathway by which fatty acids are metabolized. However, there are other minor pathways for fatty acid metabolized. These include alpha-oxidation (for branched fatty acids) and omega-oxidation.
In saturated fatty acid oxidation, the first step is a dehydrogenase reaction. This yields a trans double bond on carbons 2 and 3 from the CoA end. A product of the reaction is FADH2 which can be used to make ATP. In oxidation of an unsaturated fatty acid, the double bond is not recognized by the dehydrogenase reaction therefore you have to use a secondary isomeration reaction to produce the same product as you did in saturated fatty acid oxidation. This skips the effective "first step" and does not produce FADH2 meaning less ATP is produce.
Fatty acids synthesis starts with acetyl-CoA and builds up by the addition of two carbon units. The synthesis occurs in the cytoplasm in contrast to the degradation (oxidation), which occurs in the mitochondria. Many of the enzymes for the fatty acid synthesis are organized into a multienzyme complex called fatty acid synthetase. The major sites of fatty acid synthesis are adipose tissue and the liver
Nonpolar fatty acid chains are nonpolar and prevent the cell from dissolving.
A fatty acid is a carboxylic acid (an acid with a -COOH group) with long hydrocarbon side chains.

Ketosis and acidosis are consequences of the incomplete oxidation of fatty acids. This is commonly found in poorly controlled diabetes.
Fatty acid oxidation is the process in which fatty acids are broken down by tissues to produce energy. Fatty acids are the residue left from fats being broken down.
Aerobic respiration of glucose -> Carbonic acid Anaerobic respiration of glucose -> Lactic acid Incomplete oxidation of fatty acids -> Acidic ketone bodies Oxidation of sulfur-containing amino acids -> Sulfuric acid Hydrolysis of phosphoproteins and nucleic acids -> Phosphoric acid

acetyl CoA
Acetyl CoA
Ketone bodies are produced by the rapid and incomplete breakdown of fatty acids. Examples of ketones include acetone, acetoacetic acid and beta-hydroxybutyric acid.

12 carbon long fatty acid is catabolized by B-oxidation. What is the final net yield of ATP? ________ just give the number with no words
We should take even numbered fatty acid because even numbered fatty acid can easily be oxidized through beta oxidation for energy production but to oxidize odd numbered fatty acid, some other enzymes are needed..... psyche....
Not directly. Fatty acid β-oxidation results in acetyl CoA, which is then entered to the Citric Acid cycle. The "last" step of the cycle is the formation of oxaloacetate from malate.
