Hexacosanoic Acid

Hexacosanoic Acid

Explanation: Hexacosanoic acid is a saturated fatty acid that is normally broken down by specific enzymes in cellular structures called peroxisomes. This fatty acid is particularly important because elevated levels are associated with adrenoleukodystrophy, a genetic disorder affecting the nervous system where very long-chain fatty acids accumulate due to defective peroxisomal metabolism.

Test purpose:

• Diagnose peroxisomal disorders like adrenoleukodystrophy.
• Monitor very long-chain fatty acid metabolism abnormalities affecting the nervous system.
