Antioxidant activity of milk and polyphenol-rich beverages during simulated gastrointestinal digestion of linseed oil emulsions.
Lamothe S, Guérette C, Dion F, Sabik H, Britten M. Lamothe S, et al. Food Res Int. 2019 Aug;122:149-156. doi: 10.1016/j.foodres.2019.03.068. Epub 2019 Apr 1. Food Res Int. 2019. PMID: 31229066
In comparison to milk, the antioxidant activity of polyphenol-rich beverages was at least four times higher. During digestion of a PUFA-rich emulsion, the formation of 4-hydroxyhexanal (4-HHE) and 4-hydroxynonenal (4-HNE) in the intestinal phase were respectively re …

Products and mechanisms of the gas-phase reactions of OH radicals with 1-octene and 7-tetradecene in the presence of NO.
Aschmann SM, Tuazon EC, Arey J, Atkinson R. Aschmann SM, et al. Environ Sci Technol. 2010 May 15;44(10):3825-31. doi: 10.1021/es100550n. Environ Sci Technol. 2010. PMID: 20420450
In the presence of approximately 1.5 x 10(14) molecules cm(-3) of NO, the respective molar formation yields of heptanal and 4-hydroxyhexanal were 28 +/- 3% and 4% from 1-octene, and 86 +/- 11% and 6% from 7-tetradecene. The 4-hydroxyhexanal yield incre …

Identification of hydroxyalkenals formed from omega-3 fatty acids.
Beckman JK, Howard MJ, Greene HL. Beckman JK, et al. Biochem Biophys Res Commun. 1990 May 31;169(1):75-80. doi: 10.1016/0006-291x(90)91435-u. Biochem Biophys Res Commun. 1990. PMID: 2140937
The major hydroxyalkenal formed from both fatty acids was a diene analog of 4-hydroxynonenal, 4-hydroxynona(2,6)dienal, while 4-hydroxyhexanal was a minor product. Measurement of specific omega-3 lipid peroxidation products may be important in studies using dietary …

1,4-hydroxycarbonyl products of the OH radical initiated reactions of C5-C8 n-alkanes in the presence of NO.
Reisen F, Aschmann SM, Atkinson R, Arey J. Reisen F, et al. Environ Sci Technol. 2005 Jun 15;39(12):4447-53. doi: 10.1021/es0483589. Environ Sci Technol. 2005. PMID: 16047780
GC-MS analyses showed the presence of the oximes of 5-hydroxy-2-pentanone and 4-hydroxypentanal from the n-pentane reaction; 5-hydroxy-2-hexanone, 6-hydroxy-3-hexanone, and 4-hydroxyhexanal from the n-hexane reaction; 5-hydroxy-2-heptanone, 6-hydroxy-3-heptanone, 1- …

Schumer EM, Trivedi JR, van Berkel V, Black MC, Li M, Fu XA, Bousamra M 2nd. Schumer EM, et al. J Thorac Cardiovasc Surg. 2015 Dec;150(6):1517-22; discussion 1522-4. doi: 10.1016/j.jtcvs.2015.08.092. Epub 2015 Aug 31. J Thorac Cardiovasc Surg. 2015. PMID: 26412316 Free article.
Concentrations of 2-butanone, 3-hydroxy-2-butanone, 2-hydroxyacetaldehyde, and 4-hydroxyhexanal were measured. The overall population was divided into 3 groups: those with lung cancer, benign disease, and healthy controls. ...
