1. The effects of 3-, 4- and 5-thia-substituted fatty acids on mitochondrial and peroxisomal beta-oxidation have been investigated. When the sulphur atom is in the 4-position, the resulting...
Hvattum, E, Skrede, S, Bremer, J, Solbakken, M
The metabolism of [1-14C]tetradecylthiopropionic acid (TTP), a 4-thia stearic acid, and its sulphoxide, [1-14C]texadecylsulphoxypropionic acid (TTP-SO), has been studied in intact rats, in isolated...
Hormonal and substrate regulation of 3-thia fatty acid metabolism in Morris 7800 C1 hepatoma cells.
Hvattum, E, Grav, H J, Bremer, J
The 3-thia fatty acid tetradecylthioacetic acid (TTA) has recently been shown to inhibit growth rate and increase peroxisomal acyl-CoA oxidase (ACO) (EC 1.3.99.3) activity in the Morris 7800 C1...
Methionine metabolism by rat muscle and other tissues. Occurrence of a new carnitine intermediate.
Scislowski, P W, Hokland, B M, Bremer, J, Davis, E J
Perfused rat hindquarter preparations were shown to incorporate radioactivity from [U-14C]methionine into citrate-cycle intermediates, lactate, alanine, glutamate, glutamine and CO2. During...

1. beta-Oxidation of gamma-linolenoylcarnitine, arachidonoylcarnitine and docosahexaenoylcarnitine by isolated rat liver mitochondria is inhibited by uncoupling conditions. Partial re-activation is...
Bjerve, K S, Daae, L N, Bremer, J
The positional and fatty acid specificity of phosphatidic acid biosynthesis in rat liver mitochondria and microsomal fractions was studied by using acylcarnitines, CoA and an excess of carnitine...
1. A spectrophotometric direct-reading assay for measurements of beta-oxidation by intact mitochondria is described. The procedure relies on the ability of ferricyanide to trap reducing equivalents...
Rates of acylcarnitine oxidation by isolated heart mitochondria from various animal species were measured polarographically, and by using a spectrophotometric assay [see Osmundsen & Bremer (1977)...
The effect of disulphides on mitochondrial oxidations
Skrede, S., Bremer, J., Eldjarn, L.
1. Nicotinamide nucleotide-linked mitochondrial oxidations were inhibited by the disulphides NNN′N′-tetraethylcystamine, cystamine and cystine diethyl ester, whereas l-homocystine, oxidized...
Verbeke, S, Gotteland, M, Fernández, M, Bremer, J, Ríos, G, Brunser, O
Aims: Gluten ingestion in coeliac disease is associated with alterations of the intestinal mucosa, especially the expansion of the lamina propria. Antiendomysium and antireticulin antibodies may...
