Peroxisomal 2-Hydroxyacyl-CoA Lyase Is Involved in Endogenous Biosynthesis of Heptadecanoic Acid [PDF]

open access: yesMolecules, 2017
Circulating heptadecanoic acid (C17:0) is reported to be a pathology risk/prognosis biomarker and a dietary biomarker. This pathology relationship has been shown to be reliably predictive even when independent of dietary contributions, suggesting that ...

Catalyst-free Click PEGylation reveals substantial mitochondrial ATP synthase sub-unit alpha oxidation before and after fertilisation. [PDF]

open access: yesRedox Biol, 2019
Using non-reducing Western blotting to assess protein thiol redox state is challenging because most reduced and oxidised forms migrate at the same molecular weight and are, therefore, indistinguishable. While copper catalysed Click chemistry can be used to ligate a polyethylene glycol (PEG) moiety termed Click PEGylation to mass shift the reduced or ...

Refsum disease: a defect in the alpha-oxidation of phytanic acid in peroxisomes

open access: yesJournal of Lipid Research, 1993
The oxidation of phytanic acid to pristanic acid was previously demonstrated to be deficient in monolayer cultures of skin fibroblasts (Herndon et al. 1969. J. Clin. Invest. 48: 1017-1032).

Alpha-Oxidation

open access: yesBiochimica et Biophysica Acta (BBA) - Molecular Cell Research, 2006
Phytanic acid (3,7,11,15-tetramethylhexadecanoic acid) is a branched chain fatty acid, which is a constituent of the human diet. The presence of the 3-methyl group of phytanic acid prevents degradation by beta-oxidation. Instead, the terminal carboxyl group is first removed by alpha-oxidation.

Fractionation of sulfur isotopes during heterogeneous oxidation of SO2 on sea salt aerosol: a new tool to investigate non-sea salt sulfate production in the marine boundary layer [PDF]

open access: yesAtmospheric Chemistry and Physics, 2012
The oxidation of SO2 to sulfate on sea salt aerosols in the marine environment is highly important because of its effect on the size distribution of sulfate and the potential for new particle nucleation from H2SO4 (g). However, models of the sulfur cycle

Phytanic acid oxidation: normal activation and transport yet defective alpha-hydroxylation of phytanic acid in peroxisomes from Refsum disease and rhizomelic chondrodysplasia punctata

open access: yesJournal of Lipid Research, 1996
In humans the oxidation of phytanic acid is a peroxisomal function. To understand the possible mechanisms for the pathognomic accumulation of phytanic acid in plasma and body fluids of Refsum disease (RD) and rhizomelic chondrodysplasia punctata (RCDP ...

Alpha‐oxidation of 3‐methyl‐substituted fatty acids and its thiamine dependence [PDF]

open access: yesEuropean Journal of Biochemistry, 2003
3‐Methyl‐branched fatty acids, as phytanic acid, undergo peroxisomal α‐oxidation in which they are shortened by 1 carbon atom. This process includes four steps: activation, 2‐hydroxylation, thiamine pyrophosphate dependent cleavage and aldehyde dehydrogenation.

Synthesis of 3 alpha,7 alpha,12 alpha,25-tetrahydroxy-5 beta-cholestan-24-one, an intermediate in the 25-hydroxylation pathway of cholic acid biosynthesis from cholesterol

open access: yesJournal of Lipid Research, 1983
This paper describes the chemical synthesis of 3 alpha,7 alpha,12 alpha,25-tetrahydroxy-5 beta-cholestan-24-one via selective oxidation of 5 beta-cholestane-3 alpha,7 alpha,12 alpha, 24 xi,25-pentol with silver carbonate on celite.

Improved quantification of microbial CH4 oxidation efficiency in arctic wetland soils using carbon isotope fractionation [PDF]

open access: yesBiogeosciences, 2013
Permafrost-affected tundra soils are significant sources of the climate-relevant trace gas methane (CH4). The observed accelerated warming of the arctic will cause deeper permafrost thawing, followed by increased carbon mineralization and CH4 formation ...

Oxidation of LDL by recombinant human 15-lipoxygenase: evidence for alpha-tocopherol-dependent oxidation of esterified core and surface lipids

open access: yesJournal of Lipid Research, 1996
Various lipoxygenases (LO) oxidize low density lipoprotein (LDL) in vitro and 15-LO has been implicated in the development of atherosclerosis in vivo.
