식용죽순의 질소대사에 미치는 아미노산의 페턴에 관하여

PATTERN OF THE AMINO ACIDS INFLUENCED ON NITROGEN METABOLISM OF EDIBLE BAMBOO SPROUTS

농촌에서 식용으로 사용하는 두종의 죽순에 대하여 함유하는 아미노산을 생장부위에 따라 정성분석하였다. 대체로 한 종류가 함유하는 아미노산은 5종 내지 15종이었으며 축순의 생장과정에 따라 함유된 아미노산의 종류는 명명 상위하였다. 식용 죽순에 함유된 필수 아미노산의 종류는 4종에서 9종임을 정성분석 할 수 있었다. 식용죽순에 잇어서도 다른 식물성 식품과 같이 영양가치가 있음을 알아 내었다. 선단부 보다 기부에 아미노산의 종류가 많이 분석된 것은 기부에서 부터 질소대사가 촉진되어 간다는 것을 추측케 하였다.

KWON, Oh Yong (Chunju Teacher's Coll.) Partern of the amino acids influedced on nitrogen metabolism of edible bamboo sprouts. Kor. Jour. Bot. VI (4) : 5-10, 1963. It had been scarcely reported by any worker that the essential amino acids to be indispensable in our daily life contained in edible bamboo sprouts and that they had various pattern of free amino acids. For this reason, especially two species of Korean bamboo sprouts collected from the surburb of Chunju, in April, 1963 were used for researching the essential amino acids and free amino acids appeared on paper chromatography. The most suitable part for our edibles was investigated as a part of bio-chemical studies on Korean bamboo sprouts. The free amino acids contained in two species were found as 5-15 kinds and there were a few of difference according to it's growing parts. Many kinds of free amino acids were found in the end parts more than the tip parts and mid parts of bamboo sprouts. Besides, the essential amino acids in each species were found to 3-9 kinds. From the characteristics and the experiments marked above, it was suggested to the author that many kinds of free amino acids in the end part accelerated the formation of nitrogen comounds more than the other parts.
