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 | |

Fatty acyl CoA elongation in the endoplasmic reticulum | This shows the overall process of fatty acyl elongation in the endoplasmic reticulum. The process resembles that catalyzed by fatty acyl synthase, but the individual activities appear to be on separate enzymes. | Knowledge Weavers Fatty Acids | |

 |
Propionyl CoA carboxylase reaction | Propionyl CoA is metabolized by a process that first converts it to D-methylmalonyl CoA. The reaction is catalyzed by propionyl CoA carboxylase,and requires energy in the form of ATP. | Biosynthesis | Knowledge Weavers Fatty Acids |

Linoleic acid structure | Linoleic acid is a typical polyunsaturated fatty acid. | Knowledge Weavers Fatty Acids | |

 |
Reduction of a 2,4-dienoyl CoA | The reduction of 2,4-dienoyl CoA by NADPH is a step in the oxidation of polyunsaturated fatty acids. It is ironic that a reduction reaction is a required step in a process that is oxidative. | Knowledge Weavers Fatty Acids | |

Complete oxidation of an odd-chain fatty acid -- overview | This diagram indicates production of propionyl CoA from an odd-chain fatty acid and the subsequent conversion of propionyl CoA to succinyl CoA, which can be metabolized through the citric (tricarboxylic) acid cycle. | Biosynthesis | Knowledge Weavers Fatty Acids |

 |
Initiation of beta-oxidation | An acetyl group is transferred from acetyl CoA to the -SH group of the condensing enzyme domain of fatty acyl synthase, forming acetyl-CE. The reaction is catalyzed by the acyltransferase activity of fatty acyl synthase. | Knowledge Weavers Fatty Acids | |

 |
Fatty acid metabolism -- schematic overview | Fatty acids are taken up by cells, where thy may serve as precursors in the synthesis of other compounds, as fuels for energy production, and as substrates for ketone body synthesis. Ketones bodies may then be exported to other tissues, where they can be used for energy production. | Biosynthesis | Knowledge Weavers Fatty Acids |

 |
Condensation of an acyl group with a malonyl group | The acetyl group displaces the carboxyl of the malonyl group, forming a beta-ketoacyl group. This reaction is catalyzed by beta-ketoacyl Acyl Carrier Peptide synthase. The carboxyl released in the form of bicarbonate regenerates the bicarbonate used earlier in the acetyl CoA carboxylase reaction. | Knowledge Weavers Fatty Acids | |

Essential features of a fatty acid | The essential features of a fatty acid are a long hydrocarbon chain terminating in a carboxylic acid group. | Knowledge Weavers Fatty Acids | |
