Gelatinization with formic acid.
1. A study has been made of the gelatins obtained by treating a number of fresh and fossil collagens with dilute formic acid. 2. Compositions of their peptides separated by filtration through polyacrylamide gels has been established. 3. Solubilization results in the freeing of much aspartic acid and less glycine, the amounts being determined for the collagens investigated.
