“…The type of cerumen produced by an individual is defined by a single nucleotide polymorphism in the ATP-binding cassette C11 gene. , Dry-type individuals are homozygous for adenine while the wet-type exhibit at least one guanine. Investigations of the molecular content of cerumen have revealed the presence of a number of compound classes such as organic acids, − amino acids, , carbohydrates, lipids, ,, alcohols, ,, hydrocarbons, ,, and esters. , The analysis techniques used include gas chromatography (GC), , gas chromatography–mass spectrometry (GC–MS), , pyrolysis GC–MS, two-dimensional GC–MS (GC × GC–MS), column chromatography, paper chromatography, , and thin layer chromatography. ,, …”
