This article provides an overview of fatty acids in meat, their variation among animal species, and the roles as flavor precursors. Animal fat mostly consists triglycerides phospholipids. Fats from ruminant (cattle, sheep, goats) monogastric (pigs horses) animals have similar with more saturated monounsaturated than polyunsaturated acids. In animals, muscle reflect composition diets, whereas ar...

It was previously shown that a high plasma concentration of non-esterified fatty acids (NEFA) persisted after a fatty breakfast, but not after an isoenergetic carbohydrate breakfast, adversely affecting glucose tolerance. The higher concentration after the fatty breakfast may in part have been a result of different mobilization rates of fatty acids. This factor can be investigated as NEFA mobil...

What are trans fatty acids (TFA)? Fatty acids found in foods can be saturated (SFA, no double bonds), monounsaturated (MUFA, 1 double bond) or polyunsaturated (PUFA , 2 or more double bonds). The double bonds provide rigidity to the molecule and result in specific molecular configurations. Naturally occurring fatty acids in foods usually have the cis configuration, i.e. the hydrogen atoms with ...

  Eviscerated sea bass, Dicentrarchus labrax were irradiated by Cobalt-60 at commercial irradiation facility at dose of 2.5 and 5 kGy at 2–4°C. The influences of the irradiation on proximate, fatty acid and amino acid composition in cultured sea bass were investigated. Significant differences (P < 0.0.5) were found between non-irradiated and irradiated sea bass in terms of moisture, protein, fa...

Current evidence indicates that chylomicron remnants (CMR) induce macrophage foam cell formation, an early event in atherosclerosis. Inflammation also plays a part in atherogenesis and the transcription factor nuclear factor-kappaB (NF-kappaB) has been implicated. In this study, the influence of CMR on the activity of NF-kappaB in macrophages and its modulation by the fatty acid composition of ...

Sphingomyelin, ceramide, cerebroside, and cerebroside sulfate from beef brain were isolated by column chromatography in quantitative yield and in pure form. The fatty acid composition of each sphingolipid was determined by gas-liquid chromatography (GLC). Sphingomyelin contained only nonhydroxy fatty acids, while cerebroside, cerebroside sulfate, and ceramide contained both nonhydroxy and hydro...

The main role of fatty acids is focused on serving as major substrates for energy production; however, fatty acids are also involved in the formation of cellular structures as well as in the transmission of cellular signals. Among the multiple functions attributed to fatty acids are their anti-inflammatory properties. This important characteristic has been applied in the prevention, attenuation...

BACKGROUND Maternal obesity may program the fetus and increase the susceptibility of the offspring to adult diseases. Metformin crosses the placenta and has been associated with decreased inflammation and reversal of fatty liver in obese leptin-deficient mice. We investigated the effects of metformin on maternal and fetal lipid metabolism and hepatic inflammation using a rat model of diet-induc...

In this study, we compared qualities and physiochemical traits of meat from Berkshire (black color) pigs with those of meat from 3-way Landrace (white color) × Yorkshire (white color) × Duroc (red color) crossbred pigs (LYD). Meat quality characteristics, including pH, color, drip loss, cooking loss, and free amino acid, fatty acid, vitamin, and mineral contents of longissimus dorsi muscles, we...
