Abstract

참달팽이(Koreanohadra koreana)는 환경부에서 지정한 법정보호종(멸종위기 야생생물 II급)이며, 전라남도 신안군 홍도와 하태도에서만 서식하는 한국고유종이다. 반면, 그 동안 참달팽이 지방산에 대한 연구는 진행된 바 없다. 홍도와 하태도를 대상으로 계절, 미소서식처, 지역 차이에 따른 참달팽이의 지방산 구성 변화를 비교하기 위해 분석에 사용한 표본의 개수는 총 99개였다. 실험결과 총 16가지의 지방산이 검출되었으며, 주로 식물질 먹이에서 유래되는 다중불포화지방산(PUFAs)이 53.6%로 가장 높았다. 반면, 동물성 또는 미생물에서 유래하는 단일불포화지방산(MUFAs)은 31.4%, 포화지방산(SFAs)은 15.0%로 상대적으로 적게 검출되었다. 참달팽이의 총 지방산량 변화는 PUFAs의 변화와 가장 강한 상관관계(R2=0.88, p < 0.0001)를 보였다. 계절별로 PUFAs는 봄 (13.20 mg/g)과 여름 (13.08 mg/g)이 가을 (12.06 mg/g)과 겨울 (12.40 mg/g)에 비해 많은 양이 검출되었다. 미소서식처별 PUFAs는 초지대(12.80 mg/g)에서 석회질 지대(12.48 mg/g) 보다 다소 높게 나타났다. 반면, 지역별로 홍도(12.65 mg/g)와 하태도(12.64 mg/g)는 차이가 거의 없었다. PUFAs는 참달팽이의 먹이원을 기반으로 한 서식지의 질을 추적할 수 있는 하나의 지표로서 활용가치가 높을 것으로 기대된다.
