To find out the fatty acid profile of wild female Cynoglossus gracilis in breeding stage, the fatty acid composition in three tissues (muscle, liver and ovary) were analyzed using the national standard method. The results indicated that: (1) The total lipid contents in muscle, liver and ovary were 4.30 % ± 0.82 %, 25.81 % ± 1.33 % and 32.25 % ± 5.59 %, respectively. (2) The content of SFA in the liver was significantly lower than that in muscle and ovary (P > 0.05). The content of MUFA was significantly different between tissues (P > 0.05): highest in the liver, and lowest in the ovary. Within MUFAs the fatty acid 18:1n-9c was highest, reaching 38.63 % ± 4.13 %, 44.98 % ± 3.85 % and 28.59 % ± 1.08 % in muscle, liver and ovary, respectively. PUFA, n-3PUFA, DHA, EPA and DPA were all highest in the ovary.

Endurance trained ( n = 14) and untrained young men ( n = 15) were compared regarding the fatty acid profile of the vastus lateralis muscle after 8 wk on diets with a similar fatty acid composition. The skeletal muscle phospholipids in the trained group contained lower proportions of palmitic acid (16:0) (−12.4%, P < 0.001) and di-homo-γ-linolenic acid [20:3(n-6)] (−15.3%, P = 0.018), a lower n-6-to-n-3 ratio (−42.0%, P = 0.015), higher proportions of stearic acid (18:0) (+9.8%, P = 0.004) and sum of n-3 polyunsaturated fatty acids (+33.8%, P = 0.009), and a higher ratio between 20:4(n-6) to 20:3(n-6) (+18.4%, P = 0.006) compared with those in the untrained group. The group differences in 16:0, 20:3(n-6), 18:0/16:0, and 20:4(n-6)/20:3(n-6) were independent of fiber-type distribution. The trained group also showed a lower proportion of 16:0 (−7.9%, P < 0.001) in skeletal muscle triglycerides irrespective of fiber type. In conclusion, the fatty acid profile of the skeletal muscle differed between trained and untrained individuals, although the dietary fatty acid composition was similar. This difference was not explained by different fiber-type distribution alone but appears to be a direct consequence of changes in fatty acid metabolism due to the higher level of physical activity.

Significant Difference

The present study was designed to investigate whether meat-type rabbits are able to perform treadmill running as a daily routine exercise, and if so, whether the exercise induces specific proportional changes in the fatty acid composition of their muscles. After a four-week training period 8-week-old rabbits were slaughtered and the total activity of plasma lactate dehydrogenase was measured, showing a significant difference between the exercised and control groups (429 ± 126 IU/l vs. 639 ± 203 IU/l). Furthermore the fatty acid composition of m. longissimus dorsi (MLD) and m. vastus lateralis (MVL) was determined by means of gas chromatography. Exercise increased the proportions of oleic acid (C18:1 n-9) in both MLD and MVL as compared to the control group. However, the level of stearic (C18:0) and arachidonic (C20:4 n-6) acids significantly decreased in the MVL after the exercise. Changes in the fatty acid profile resulting from the physically loaded condition were of the same tendency in both muscles, adding that the MVL might have been exposed to the exercise more intensively; alterations there occurred in a more pronounced manner. Based on the inference that the composition of membrane structure was also affected, these alterations may have important consequences on meat quality.

Abstract The aim of this study was to estimate fatty acid composition, health related lipid indices (atherogenic-AI and thrombogenic-IT indices, h/H ratio) and the correlation between these traits and cholesterol content in various tissues of fatteners. The experiment involved 60 crossbred pigs (PL × PLW) × Duroc. The animals were slaughtered at 115 ± 2.0 kg body weight. The tissue samples (backfat, m. longissimus, liver, heart) were collected to analyze fatty acid profile and cholesterol content. The highest PUFA level was determined in the fat of the heart and liver. Weak to moderate correlations were observed between cholesterol content and most of the studied indices of fatty acid profile of the analyzed tissues. Importantly, the most significant correlations were established between the examined traits in the heart fat. Generally, irrespective of tissue type, the cholesterol level was negatively correlated with total PUFA, n-3 and n-6 FA content and h/H ratio.
