A histoenzymatic investigation of galactogen synthesis in the albumen gland of Helix pomatia and Lymnaea stagnalis

Summary A histoenzymatic investigation of Galaotogen synthesis has been attempted in the albumen gland of Helix pomatia and Lymnaea stagnalis. Using histoenzymatic methods the authors succeeded in finding only two enzymes (E.C. 2.7.7.9.=uridylyltransferase and E. C. 5.1.3.2.=epimerase) demonstrated by biochemical assays and isolated. They therefore assume that there may be other metabolic pathways in addition to those demonstrated by biochemical methods.
