Calcium ( II ) precipitates with palmitate ( Pal ( - ) ) , a process affecting calcium absorption in the gut , in a first - order reaction , as followed by a calcium electrode in neutral aqueous solution for excess of calcium ( II ) , with a rate constant showing a minimum at physiological ionic strength of 0 . 32 +/- 0 . 09 d ( - 1 ) at 25 degrees C with a stoichiometry of 1 . 79 +/- 0 . 03 , lower than the expected 1 : 2 .
 Chemical: Calcium ( II ); Chemical: palmitate; Chemical: Pal ( - ); Chemical: calcium; Chemical: calcium; Chemical: calcium ( II )
