Calcium ions (Ca 2+) contribute to the physiology and biochemistry of organisms' cells. They play an important role in signal transduction pathways, [ 2 ] [ 3 ] where they act as a second messenger , in neurotransmitter release from neurons , in contraction of all muscle cell types, and in fertilization .
Calcium metabolism is the movement and regulation of calcium ions (Ca 2+) in (via the gut) and out (via the gut and kidneys) of the body, and between body compartments: the blood plasma, the extracellular and intracellular fluids, and bone.
14 sie 2023 · Serum calcium is often chelated into the ionic complexes of calcium phosphate, calcium carbonate, and calcium oxalate. Finally, free calcium, which makes up 51% of the serum calcium, is utilized by the body to maintain physiologic functions.
8 sty 2024 · Calcium is a prominent molecule in the body involved in many biochemical processes. This mineral is essential for proper cardiac function, the structural integrity of bone, muscular contraction, and acts as an enzymatic signal in biochemical pathways.[1]
13 maj 2022 · Calcium homeostasis, i.e., maintaining a blood calcium level of about 10 mg/dL, is critical for normal body functions. Hypocalcemia can result in problems with blood coagulation, muscle contraction, nerve functioning, and bone strength.
Calcium homeostasis refers to the maintenance of a constant concentration of calcium ions in the extracellular fluid. It includes all of the processes that contribute to maintaining calcium at its “set point.”
Calcium ion is an essential cellular secondary messenger influencing a multitude of events including modulation of Ca2+ -dependent enzymes involved in signal transduction, gene transcription, cell death and survival programs (Dolmetsch et al., 1998; Meldolesi, 1998).
