Peroxisomes
Very-long-chain fatty acid oxidation
Also searched as Very-long-chain fatty acid oxidation.
Mitochondria Cannot Oxidize the Longest Fatty Acids — peroxisomes shorten them first and hand them over. The process generates hydrogen peroxide deliberately, which is why catalase is concentrated here.
In depth
An organelle handling very-long-chain fatty acids, plasmalogen synthesis and bile acid intermediates.
What drives it
Fatty-acid oxidation increases it.
PPAR-alpha is the transcription factor that induces peroxisomal proliferation and its beta-oxidation enzymes - the receptor is named for it. Carried by the hepatic lipid-metabolism reviews. doi 10.1016/j.jhep.2023.03.017 · PMC10132248
Fasting response increases it.
Fasting raises PPAR-alpha signaling and with it peroxisomal fatty-acid handling. Carried by the hepatic lipid-metabolism reviews. doi 10.1016/j.jhep.2023.03.017 · PMC10132248
Liver increases it.
Peroxisomes are most abundant in hepatocytes, where very-long-chain fatty acid and bile acid processing occurs. Carried by the hepatic lipid-metabolism reviews. doi 10.1016/j.jhep.2023.03.017 · PMC10132248
What it drives
It increases Peroxide-clearing enzyme.
Catalase is concentrated where hydrogen peroxide is made deliberately. Carried by the intermediary-metabolism, micronutrient and redox reviews. doi 10.3390/nu18132141 · PMC9967593
It increases Fat burning.
Mitochondria cannot oxidize the longest fatty acids - peroxisomes shorten them first and hand them over. Carried by the intermediary-metabolism, micronutrient and redox reviews. doi 10.3390/nu18132141 · PMC9967593
It increases Membrane lipids.
Plasmalogen synthesis begins in the peroxisome, so peroxisomal function limits it. Carried by the intermediary-metabolism, micronutrient and redox reviews. doi 10.3390/nu18132141 · PMC9967593
It reduces Oxidative stress.
Net effect depends on catalase capacity - the organelle generates hydrogen peroxide deliberately. Carried by the intermediary-metabolism, micronutrient and redox reviews. doi 10.3390/nu18132141 · PMC9967593
It increases Gut-liver bile signaling.
Bile acid intermediates are processed here. Carried by the intermediary-metabolism, micronutrient and redox reviews. doi 10.3390/nu18132141 · PMC9967593
