Abstract

The annual averages of total lipid, total fatty acid and the ratios of fatty acids in

muscle and liver lipids of pikeperch from Lake Egirdir were determined. The quality

of muscle and liver lipids with respect to the ratio of n-3 fatty acids was evaluated.

Total lipid contend was found 0.617r in male muscle. 0.56'7rin female muscle.

5.7191- in male Iiver and 5.147(' in female Iiver. Total fatty acids composed of more

than half of total lipid in muscle and liver in both sexes. Palmitic acid (16:0) in

saturated fatty acids (SF A), oleic acidt 18: 1) in monounsaturated fatty

acids(M UF A),docosahexaenoic(22 :6n-3). eicosapentaenoic(10:5 n- 3) and

arachidonic(20:4n-6) acids in polyunsaturated fatty acids(PUFA) were predominant.

The n-3 fatty acids ratios were found 15.52'7(' in male muscle. 16.71 '7C'infemale

muscle, 12.02C'k in male liver and 11.26'7c in female liver. Although total lipid

contend is very low, pikeperch may be a source of n-3 fatty acids for the people who

have constantly consumption habits because the ratio ofn-3/n-6 is relatively high.

EGiRDiR GOLU'NDE YASAYAN SUDAK (Stizostedion lucioperca) BALIKLARININ 0-3 YAG ASİTLERi ORANI VE SAGLIK UZERiNE ETKisiNiN DEGERLENDiRiLMESi

Abstract

Egirdir Golu'nde yasatan sudak baliklannm kas ve karaciger IlfJ."c:rmin yillrk

ortalama total lipit, total yag asidi ve yag asidi oranlan tespit edilrnistir. n-3 yag

asitleri orarn ile ilgili olarak da kas ve karaciger lipit kalitesi degerlendirilmistir.

Total lipid icerigi erkeklerin kas dokusunda % 0.61, disilerin kas dokusunda %0.56,

erkeklerin karacigerinde %5.71, disilerin karacigerinde %5.14 bulunmustur, Her iki

eseyde de total lipit iceriginin yansmdan fazlasm: total yag asitleri olusturrnustur.

Doymus yag asitlerinden(SF A) palmitik as it, tek cift bagl: doyrnarms yag

asitlerinden(MUF A) oleik asit, cok doyrnarms yag asitlerinden (PUF A)

dokosaheksaenoik (22:6n-3), okosapentaenoik (20:5n-3) ve arasidonik (20:4n-6)

asitler en cok bulunan yag asitleridir. n-3' yag asitleri oraru erkeklerin kas

dokusunda %15.52, karacigerinde %12.02, disilerin kas dokusunda %16.71.

kareacigerinde % 11.26 bulunmustur, Total lipit icerigi cok dusuk olmasma ragmen

n-3/n-6 orarn nisbeten yuksek oldugundan sudak baliklan surekli tUketim ahskanligi

olanlar icin bir n-3 yag asidi kaynagi alabilir.
