Non‐Polar Lipid Components of Human Cerumen

Abstract: Human cerumen was separated by column chromatography into the following groups of compounds: hydrocarbons, squalene, wax esters and cholesterol esters, triacylglycerols, free fatty acids, free fatty alcohols, monoacylglycerols, free cholesterol, free sterols, and free hydroxy acids. The groups of compounds obtained were examined in detail by gas chromatography and gas chromatography-mass spectrometry. In total, about one thousand compounds have been identified.

“…Qualitatively, VOCs were similar across the two ethnic groups with volatile C 2 –C 6 organic acids consistently observed. Ketones (e.g., 6-methyl-5-heptene-2-one, trans-geranylacetone) were also detected and may originate from the oxidation of squalene [27–29], a dominant component of cerumen [20–23]. Most volatile acids, alcohols and aldehydes found in skin secretions originate from interactions between non-odorous sebaceous gland secretions and cutaneous bacteria [30, 31].…”

“…Although many studies have focused on the chemistry of human axillary odorants, to date, there are no data regarding the volatile organic compounds (VOCs) associated with human cerumen. The composition of cerumen has been assessed by several techniques (e.g., gas-chromatography [GC], gas chromatography–mass spectrometry [GC/MS], high performance liquid chromatography, and thin layer chromatography), which have revealed long-chain fatty acids, alcohols, triacylglycerols, cholesterol, and squalene as the major components [1423]. Herein, we provide the first analysis of the nature and relative abundance of VOCs present in cerumen.…”

“…Squalene has been found in other human and animal fluids, such as saliva, the lipid composition of which resembles that of the skin, meibum, eyelid lipids, and cerumen, and in synovial fluid it plays an important role in accelerating oxidation in irradiated and melted ultrahigh molecular weight polyethylene under in vitro accelerated aging conditions . Variations in squalene have been found in the rat clitoral gland throughout the reproductive cycle, which has been proposed to be a female‐specific chemosignal to attract males …”

“…Mu and Hoy resolved TAG of rat lymph with RP‐APCI‐MS in accordance to the formed ammonium adducts and DAG + fragments 140. Recently, Stransky et al identified 200 TAG species of human cerumen with RP‐APCI‐MS 141. The limitation of RP‐APCI‐MS, that acylglycerols differing only in the position of DBs in individual FA cannot be resolved 28, can be overcome by silver‐ion LC.…”
