| Abstract: | Perchloric acid extracts of soybean seeds were separated by column chromatography into 17 peaks. Thirteen nucleotides were identified in 11 of these peaks (NAD, CMP, CDP, CTP, AMP, ADP, ATP, GMP, GDP, GTP, UMP, UDP, and UTP). Two of the peaks were identified as ascorbic acid and dehydroascorhic acid. Four peaks remain unidentified although one of these appears to be protein. Monophosphates decreased and triphosphates increased as development proceeded. Diphosphates were initially low and showed no statistically significant difference with maturity. The accumulation of triphosphates in late stages of development is discussed in relation to synthetic activities of the developing seeds. |
