Calcium (Ca) in plants is primarily complexed with oxalate, phytate, fiber, lactate, fatty acids, protein, and other compounds [2,3]. Although many edible plants are high in total Ca, complexation with oxalate (forming Ca-oxalate crystals) renders it undigestible (Figure 1) [4,5,6], resulting in oxalate being considered an "antinutrient".

AbstractA plant (jack bean) extract can function as a urease catalyst, similar to those of certain microorganisms such as Sporosarcina pasteurii, which can decompose urea into carbonate and ammonium ions. Carbonate ions decomposed from urea can combine with calcium ions to form calcium carbonate (usually calcite mineral). In this …

Calcium is an essential plant nutrient. It is required for various structural roles in the cell wall and membranes, it is a counter‐cation for inorganic and organic anions in the vacuole, and the cytosolic Ca 2+ concentration ([Ca 2+] cyt) is an obligate intracellular messenger coordinating responses to numerous developmental cues and environmental challenges.
