Key Words Nitrogen changes during the development of eggs of melanoplus bivittatus
Abstract The studies could be summarized as follows: 1. Standard Rf Values were made as Table 2 for the identification of amino acids. 2. Amounts of free amino nitrogen in eggs were increased about 0.03% (Table 4) while the amounts of total nitrogen (Table 3) were increased lower percentage during the ten days of development. 3. Three unknown substances were found newly during the development. 4. Eight ninhydrine positive amino acids were present, in the fresh embryonic eggs, but the numbers increased to eighteen after fifty days of development. 5. Through the development, there were large amounts of glutamic acid, aspartic acid and alanine. 6. After fifty days development, the amount of amides, such as asparagine, glutamine and alanine were increased very large which were very small amount before it and the amount of asparagine were more than that of glutamine. 7. Tryptophane, Cystine , Histidine were detected after 50 days of development. This is very remarkable fact.
