The preparation of tetragalacturonic acid
Pectic acid was subjected to partial hydrolysis by yeast polygalacturonase which was halted when the oligouronides larger than tetragalacturonic acid had disappeared, as shown paper-chromatographically.

| Zusammenfassung: | Pectic acid was subjected to partial hydrolysis by yeast polygalacturonase which was halted when the oligouronides larger than tetragalacturonic acid had disappeared, as shown paper-chromatographically. From this hydrolyzate, tetragalacturonic acid was isolated in 12.7% yield by fractional precipitation with cupric ions. Various properties of the acid were determined. |
