Alkaline phosphatase in human milk: a new heat-stable enzyme.
Alkaline phosphatase in human milk was found to be heat stable and have a molecular size of placental alkaline phosphatase, a Mr of 160,000. However, the milk alkaline phosphatase is different from placental alkaline phosphatase. The alkaline phosphatase from milk was endowed with higher surface charge and not inhibited by L-phenylalanine (2.5 mmol/l) and L-homoarginine (10 mmol/1). Both enzymes are sialylated.
