the terminal ribose residue , obtained by hydrolysis of the split product by snake venom phosphodiesterase and alkaline phosphatase , was identified as 3-deoxy-d-glycero-pentos-2-ulose by the following gas chromatography-mass spectrometric analyses : 1 ) the reduced sugar was a mixture of 3-deoxy-threo- and 3-deoxy-erythro-pentitol , and 2 ) the deuterated reduced sugar was identical with that derived from synthetic 3-deoxy-d-glycero-pentos-2-ulose .
