| Popis: | 1. 1. In the adult pulmonate snail Helisoma sp., ca 29% of the total phosphorus is present as alkylphosphonate, principally 2-aminoethylphosphonic acid (AEP), while in freshly-laid eggs, 98% is present as alkylphosphonate. 2. 2. 31P NMR analysis showed major differences in the phosphonate region of the spectrum of hot water extracts from eggs, compared to snails. 3. 3.Hot water extractable material from eggs had a mol. wt of greater than 1.5 × 106 by gel filtration and contained 2.5% AEP, 48% hexose and less than 1% amino acids. 4. 4.|AEP appears to be attached to the high mol. wt material by a phosphonomonoester bond. |
