In cells, fatty aldehydes are produced during oxidative stress-induced lipid peroxidation and by enzymatic degradation of a series of lipids including sphingosine-1-phosphate, plasmalogens, and alkylglycerols such as the platelet-activating factor. Impaired FALDH function has been shown to alter the metabolic profiles of connected pathways and can lead to the development of the SLS (dashed red arrows).
