Cholesterol maldi
Webfirst time the effects of cholesterol, cholesterol sulfate, and 3β-[N-(dimethylaminoethane)carbamoyl]-cholesterol (DC-cholesterol) on the amyloid formation of oxidized hCT. WebSterol profiles in mussels obtained by MALDI-TOFMS were in close agreement with those obtained by GC/MS. Two sterols (cholesterol and β-sitosterol) were selected for quantification as their sulphated and picolinyl esters. Calibration curves gave excellent correlation coefficients. CONCLUSIONS

WebJan 1, 2024 · In MALDI, DHB is typically used for the analysis of cholesterol, and expected spectral features include the dehydrated molecule with both H + (denoted [M + H] +) and Na + (denoted [M + Na] +) adducts ( Schiller et al., 2001 ). However, in the analysis of cholesteryl esters, the water loss is not seen because the free hydroxyl group is not … WebJun 3, 2014 · Detection of choline and phosphatidic acid (PA) catalyzed by phospholipase D (PLD) using MALDI-QIT-TOF/MS with 9-aminoacridine matrix Kyung-eui Park, Kyung-eui Park Graduate School of Life and Environmental Sciences, University of Tsukuba , Tsukuba, Japan Search for other works by this author on: Oxford Academic Google Scholar

Margarines and orange juice with added … WebCholesterol is known to have low ionization efficiency in mass spectrometry analysis and thus is also challenging in MALDI MSI. A unique feature of cholesterol analysis via mass spectrometry, compared to other lipids, is the neutral loss of water that occurs during the ionization process (Cologna, 2024; Johnson, ten Brink, & Jakobs, 2001).
