BACKGROUND Biochemical evidence has linked the coordinate control of fatty acid (FA) synthesis with the activity of stearoyl-CoA desaturase-1 (SCD1). The ratio of 16:1n-7 to 16:0 [SCD1₁₆] in plasma triacylglycerol FA has been used as an index to reflect liver SCD1₁₆ activity and has been proposed as a biomarker of FA synthesis, although this use has not been validated by comparison with isotopi...

Palmitoleic acid (PA), an algicidal compound, is used against the toxin producing dinofagelate Alexandrium tamarense, however, its impact on the edible bay scallop (Argopecten irradians) is still unclear. Therefore, we investigated the impacts of effective algicidal concentrations (20, 40, and 80 mg/L) of PA on immune responses in A. irradians. Various immune parameters including acid phosphata...

Background—Palmitoleic acid (cis-16:1n-7), produced by endogenous fat synthesis, has been linked to both beneficial and deleterious metabolic effects, potentially confounded by diverse determinants and tissue sources of endogenous production. Trans-palmitoleate (trans-16:1n-7) represents a distinctly exogenous source of 16:1n-7, unconfounded by endogenous synthesis or its determinants, that may...

In this study, the physical and chemical properties of linseed oil sesame seed were measured compared. The results showed that nitrogen content, total protein amino acids in 3.27%, 20.39%, 92158.22 μg/g FW, respectively, 2.79%, 17.43%, 92246.59 FW seeds correspondingly. content unsaturated fatty such as linolenic acid linoleic was 290.57 μg/g, 0.55 3326.69 μg/g、0.24 oil. addition, contents palm...

Microalgae are considered as a promising feedstock for the production of valuable fatty acids. In this study, individual acid profiles during growth period Chlorella vulgaris were investigated. The results showed that quantity and type acids changed with varying rates microalgal cells. Interchanging may provide some metabolic information complementary method to radiolabeling studies. For C. , t...

This study evaluated the fatty acid composition and qualitative characteristics of meat from lambs feed in feedlot with increasing levels canola grain. Meat obtained 27 fed 0, 8 16% inclusion grain were analyzed. There was a reduction content saturated acids (SFA): lauric, heptadecanoic, stearic; unsaturated (UFA): palmitoleic, oleic, eicosatrienoic, linear for ω3 ω3: ω6 ratio, while ω6: ratio ...

13C NMR was used to study the pattern of label incorporation from [2-13C]acetate into trehalose during sporulation in Saccharomyces cerevisiae. A wild-type strain and a strain homozygous for the zwf1 mutation (which affects glucose-6-phosphate dehydrogenase) were used. In the wild-type it was possible to deduce the cycling of glucose 6-phosphate around the hexose monophosphate pathway whilst in...

peel (pulp oil). Seeds contain typically around 10% oil, whereas the oil content in the soft parts varies over a much wider range from 0.5 to 10% (f. w.), largely depending on origins and varieties. Sea buckthorn seed oil and pulp oil differ considerably in fatty acid composition (Table I). While linoleic (18:2n-6) and α-linolenic (18:3n-3) acids are the major fatty acids in the seed oil, the h...

Interphotoreceptor retinoid-binding protein (IRBP) purified from monkey interphotoreceptor matrix contains relatively high concentrations of endogenous fatty acids, 6.51 mol/mol of protein. Sixty-five percent of the total fatty acid bound to IRBP was found to be noncovalently attached, with the remainder covalently bound. The fatty acids are not residual components of phospholipids or neutral l...
