    Effects of alpha-lipoic and ascorbic acid on the muscle and brain fatty acids and antioxidant profile of the South American pacu Piaractus mesopotamicus

  • Original language description

    The effects of dietary alpha-lipoic acid (LA) and vitamin C on the fatty acid (FA) composition in the brain and muscle and vitamins E and C levels in the brain were studied in the fish Piaractus mesopotamicus. A two-factorial design, where diets were devoid or supplemented with ascorbate (500 mg AA kg(-1)) and/or lipoic acid (1000 mg kg(-1)), was used. The levels of eicosapentaenoic acid (20:5n-3, EPA) increased (P<0.01) in muscle polar lipids (PL) in LA groups (6.93%+/- 0.43 vs. 5.83%+/- 0.40 and 6.68%+/- 0.53 vs. 6.00%+/- 0.39), and the same trend was also seen in the brain, however not significant. These changes are suggested to be caused by a change in lipid metabolism rather than being a direct effect of protection by LA against lipid peroxidation. No interaction of vitamin C and LA neither effects of LA on vitamin E (15.1-19.2 mg alpha-tocopherol g(-1) tissue) or vitamin C (total AA, 41.7-89.8 mu g g(-1) tissue) in brain was detected.

    Vliv alfa-lipoické kyseliny a vitamínu C na svalovinu a mastné kyseliny mozku a profil antioxidantů jihoamerického pacu Piaractus mesopotamicus

  • Czech description

    Vliv nenasycené alfa-lipoické kyseliny (LA) a vitamínu C v krmivu na složení mastné kyseliny (FA) v mozku a svalovině a úroveň vitamínu E a C v mozku byl studován u ryby Piaractus mesopotamicus. Byla použity dvou faktoriální analýza s krmivem bez a s kyselinou askorbovou (500 mg AA kg(-1)) a/nebo kyselinou lipoickou (1000 mg kg(-1)). Úroveň eicosapentaenoické kyseliny (20:5n-3, EPA) se zvýšila (P<0.01) ve svalovině pólových lipidů (PL) a ve skupinách LA (6.93%+/- 0.43 vs. 5.83%+/- 0.40 a 6.68%+/- 0.53 vs. 6.00%+/- 0.39). Obdobný vývoj byl zaznamenán také v mozku, avšak ne tak významně. Přímý vliv ochrany LA proti peroxidaci lipidu byl překryt nepřímou změnou metabolismu lipidů. V mozku nebyla objevena žádná interakce vitamínu C a LA, ani vliv LA na vitamín E (15.1-19.2 mg alfa-tokoferolu g(-1) tkáň) nebo na vitamín C (celkové AA, 41.7-89.8 mu g g(-1) tkáň).
