Phytase in Plasma and Erythrocytes of Various Species of Vertebrates

Phytate: its chemistry, occurrence, food interactions, nutritional significance, and methods of analysis

“…Phytase activity relative to animal species has also been investigated. For example, McCollum and Hart (1908) reported phytase activity in the whole blood and liver of calves, whereas Rapoport et al (1941) failed to find such activity in a number of mammals. Patwardhan (1937) first reported phytase activity in the rat, and Pileggi (1959) demonstrated that this activity was the highest in the intestinal mucosa of the rat.…”
