(1) 大阪白菜からchloroplastを単離し, その化学組成, 並びに鉄の形態を明にした。(2) 葉部の鉄はchloroplastに集中して存在することを認めた。(3) chloroplast protein中のFe : Nの比は略1 : 100であつた。(4) chloroplast protein中, 電気透析によつて, 半透膜外に出る鉄はwater soluble NaCl soluble, NaOH soluble proteinの順に多く, 膜内に残る鉄は, この順に少かつた。(5) chloroplastは全鉄の約25%のhemin-Feを含有していた。(6) chloroplastのamino-acid分布から, mono-amino acid-Nが多くarginine. cystine-Nが多くarginine. cystine-Nの含量が高いことを認めた。(1) I have isolated chloroplast from Osakasirona and proved chemical com osition and form of iron in it. (2) I have realized the iron in leaf is concentrate in it\u27s chloroplast. (3) I have realized ratio of Fe : N in the chloroplast protein is 1 : 100. (4) I have realized the iron produce from membrane by electrodialysis increases in order water-soluble NaCl-soluble and NaOH-soluble protein and the iron remains in membrane decreases in order water-soluble NaCl-soluble and NaOHsoluble protein. (5) I have realized hemin-iron of about 25% of total iron is contain in its chloroplast. (6) I have realized monoamino acid-N is much quantity and content of arginine, cystin-N is high by distribution on amino acid of chloroplast
