KWON, Oh Yong (Chunju Teacher`s coll.) Pattern of the acids influenced 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 speries 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 sppeared 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 sprouta. 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 compounds more than the other parts.
