enoyl CoA isomerase reaction | Enoyl CoA isomerase converts a trans-3-enoyl CoA to a trans-2-enoyl CoA. Thus a Delta-9 fatty acyl CoA or the product of the 2,4-dienoyl CoA reductase reaction can proceed through beta-oxidation. | Enoyl CoA Isomerase Reaction | Knowledge Weavers Fatty Acids |

 |
Structures of the ketone bodies | These are the structures of the ketone bodies. Acetoacetate and beta-hydroxybutyrate are important physiological substrates. Acetone is a byproduct, and is not metabolized further. It is excreted in the urine and in expired air. | Knowledge Weavers Fatty Acids | |

 |
Triacylglycerol structure | The structure of a typical triacylglycerol (triglyceride). | Knowledge Weavers Fatty Acids | |

 |
Dehydrogenation of fatty acyl CoA | Fatty acyl CoA is dehydrogenated by FAD in a reaction catalyzed by one of the acyl CoA dehydrogenases. Note that the dehydrogenation occurs between the alpha- and beta-carbons. | FAD | Knowledge Weavers Fatty Acids |

 |
Reduction of acetoacetate | Acetoacetate is reduced by NADH in a reversible reaction catalyzed by beta-hydroxybutyrate dehydrogenase. This reaction is the source of beta-hydroxybutyrate in the blood of individuals with ketosis. | Knowledge Weavers Fatty Acids | |

 |
Hydroxymethylglutaryl CoA synthase reaction | This irreversible reaction occurs in the mitochondria, where it is the first step in ketone body synthesis. It also occurs in the cytoplasm, where it leads to isoprenoid and steroid synthesis. | Biosynthesis | Knowledge Weavers Fatty Acids |
| 282 |
 |
Thiolase reaction | Thiolase (3-ketoacyl CoA thiolase) cleaves a long chain fatty acyl CoA, forming acetyl CoA and a long chain fatty acyl CoA that is two carbons shorter. | Knowledge Weavers Fatty Acids | |
| 283 |
 |
Beta-oxidation of a delta-9 fatty acyl CoA | Enoyl CoA isomerase is required to move the double bond in a Delta-9 fatty acyl CoA to a position where it can continue in beta-oxidation. | Knowledge Weavers Fatty Acids | |
| 284 |
 |
Thiolase reaction with acetoacetyl CoA | Thiolase (3-ketoacyl CoA thiolase) cleaves acetoacetyl CoA, forming two molecules of acetyl CoA. | Knowledge Weavers Fatty Acids | |

 |
Stearic acid structure | Stearic acid is a typical long chain saturated fatty acid. | Knowledge Weavers Fatty Acids | |

 |
Fatty acid elongation in mitochondria | This shows the overall reaction of fatty acid elongation in mitochondria. The process is essentially a reversal of beta-oxidation, except that one NADPH and one NADH are required (beta-oxidation yields two NADH). Mitochondrial fatty acid elongation acts primarily on fatty acyl CoA substrates short... | Knowledge Weavers Fatty Acids | |
