The two major forms of calcium are calcium carbonate and calcium citrate. Calcium supplements are intended to be consumed with a meal, and when taken as directed, the two forms of calcium are absorbed at roughly the same rate. However, when taken on an empty stomach, the body has a much easier time absorbing calcium in its citrate form vs. its carbonate form. Calcium lactate and calcium stearate are two alternative forms of calcium. Calcium lactate is expected to have similar effects as calcium citrate.
PHYSICAL FACTORS THAT AFFECT MICROBIAL GROWTH. TEMPERATURE. Generally,an increase in temperature will increase enzyme activity. But if temperatures get too high, enzyme activity will diminish and the protein (the enzyme) will denature. On the other hand, lowering temperature will decrease enzyme activity. At freezing temperatures enzyme activity can stop. Repeated cycles of freezing and thawing can denature proteins.
Bacterial growth increases with temperature or humidity. Lower temperatures will inhibit or completely stop bacterial growth, but not kill bacteria. The best temperatur â¦ e for fastest growth of some bacterial strains (such as E. coli) is the human body temperature at 37Â°C.However, most species cannot survive in extreme temperatures.he best temperature for bacterial growth is around the same temperature as the human body, 98.6 degrees F (37 degrees C).
