ileum 12.4% of the phosphorylation of D-fructose by ileum homogenates is attributable to ketohexokinase Rattus norvegicus
-
liver the phosphorylation of D-fructose by liver homogenates is attributable to ketohexokinase Rattus norvegicus
-
additional information there is no biologically significant amount of ketohexokinase in the parotid gland Rattus norvegicus
-
additional information semi-purified B and non-B islet cells are investigated. The major fraction of D-fructose phosphorylation by islet cell homogenates (B and non-B) is not attributable to ketohexokinase. Rattus norvegicus
-
pancreas activity of ketohexokinase in pancreas homogenates. In pancreatic islets ketohexokinase activity is present. Rattus norvegicus
