On the Sulfur-incorporation into amino acids in germinating Soy Beam seeds using Sulfate-$S^35$

대두발아종자에 있어서 아미노산에의 유황결합에 관하여

The sulfur-incorporation into amino acids in germinating Soy Bean seeds was studied with the aid of Sulfate-S35. Water imbibition and isotope absorption were almostly pararelled. On the radioautogram $S^35$ was detected in cysteic acids at 90 minutes. Cysteine, cystine and cysteic acid were appeared with radioactivity at 240 minutes after the infiltration of sulfate-$S^35$. Methione was not detected on the radioautogram in the range of 300 minutes. The radioactivity of $S^35$ was detected highly in free amino acids than hydrolyzates.
