Calcium is primarily associated with minerals rather than macromolecules. However, it plays a critical role in the structure and function of certain macromolecules, particularly proteins and nucleic acids, where it can influence their conformation and activity. For example, calcium ions can bind to specific sites on proteins, affecting their function, and it is also involved in stabilizing the structure of some nucleic acids. Additionally, calcium is a key component of biominerals, such as bone and teeth, which are rich in calcium phosphate.
No, calcium bonds to calmodulin
Actin changes shape.
Calcium ions bind to troponin and change its shape.
Calcium carbonate easily react with acids.
The two amino acids carried by the two tRNA's inside a ribosome, bind togather with a peptide bond to elongate the protein chain.

Calcium ions need to bind to the protein troponin in order to initiate muscle contraction.
No, calcium bonds to calmodulin
It reacts with acid but not soluble in water.
Calcium binds to the messenger protein Calmodulin. The calcium-calmodulin complex then activates myosin light chain kinase (MLCK), which phosphorylates myosin to allow it to bind to actin - producing contraction.
Calcium soap of fatty acids can be made by reacting calcium hydroxide with a mixture of fatty acids derived from oils or fats. This process typically involves heating the fatty acid mixture with calcium hydroxide until a soap is formed. The calcium soap can then be separated and purified for use in various applications.
No
Calcium ions bind to troponin, changing troponin's shape
Lavender (NaEDTA) and Light Blue (sodium citrate)
Actin changes shape.
Calcium ions bind to troponin and change its shape.
