Studies in the 1930–1940s, directed toward the elucidation of the connection between cell metabolism and ion—water content of human red cells, noted extreme alterations in K + leakage under various experimental conditions. In lead-poisoned red cells (rskov, 1935), and in NaF-treated cells, ...
The particle size scales with the calcium concentration inside and size of the encapsulating liposome (Tester et al., 2011). Regardless of its size, particles consist of ACC instead of one of the more stable crystalline polymorphs of calcium carbonate. We attribute the extended stability of ...
The seedlings were then collected, rinsed 4-5 times with distilled water, and dried at 70 °C for 24 h and weighed. The samples were digested with 0.1 N HNO3, and the K+ concentrations were determined with an atomic absorption spectrophotometer (model 560; Perkin-Elmer, Norwalk, CT, USA)...
So who needs calcium supplements? If you’re a picky eater, avoid dairy, or otherwise suspect you aren’t getting enough calcium from your regular diet, they could be helpful. There are two kinds to choose from: calcium carbonate and calcium citrate. Calcium carbonate offers more elemental cal...
