General description
Lathosterol is a metabolite of cholesterol present in human breast milk. Lathosterol is catabolized by lathosterol 5-desaturase to 7-dehydrocholesterol, which is a precursor of cholesterol. Lathosterol-d7 is a deuterated derivative of lathosterol.
Application
Lathosterol-d7 has been used as an internal standard in gas chromatography-mass spectrometry (GC–MS) for the breast milk sterol quantification and in liquid chromatography high resolution mass spectrometry (LC–HRMS) analysis.
Biochem/physiol Actions
Lathosterol levels are direct indicators of cholesterol levels and aid in decoding metabolism defects. Elevated levels of lathosterol is implicated in cerebrotendinous xanthomatosis (CTX) and lathosterolosis. The inactivation of enzyme lathosterol 5-desaturase (SC5D) leads to accumulation of lathosterol in lathosterolosis pathology.

Lathosterol 5-desaturase catalyzes the conversion of lathosterol to 7-dehydrocholesterol in the next to last step of cholesterol synthesis. Inborn errors of cholesterol synthesis underlie a group of human malformation syndromes including Smith-Lemli-Opitz syndrome, desmosterolosis, CHILD syndrome, CDPX2 and lathosterolosis. We

The analysis of blood for β-sitosterol and campesterol is the measures of cholesterol absorption while lathosterol is a measure of cholesterol synthesis. The biological variability of β-sitosterol, campesterol, and lathosterol was measured using liquid-chromatography tandem mass spectrometry from a cohort
