Very long chain fatty acids


A very long chain fatty acid (VLCFA) is a fatty acid with 22 or more carbons. Their biosynthesis occurs in the endoplasmic reticulum. VLCFA's can represent up to a few percent of the total fatty acid content of a cell.

Unlike most fatty acids, VLCFAs are too long to be metabolized in the , and must be metabolized in peroxisomes.

Certain peroxisomal disorders, such as adrenoleukodystrophy and Zellweger syndrome, can be associated with an accumulation of VLCFAs.
