What are the effect of a greater number of cysteine amino acids on the stability of the proteins?

Explanation:

Cysteine is a naturally occuring amino acid and it is exist in L-form abundantly .Cysteine involve in formation of sulfhydril group which is very reactive . Cysteine easily oxidised to form dimer i.e., known as Cystine . Cystine is very important to analyse the primary structure of proteins , effects while changing in secondary structure and stablization of tertiary and quaternary structure . Cysteine play very important role in three dimensional conformation of protein molecule and provide stablity . Disulfide bridge present between two cysteine are responsible for the formation of the loops of backbone and disulfide bridge also provide the stability to  loop of various proteins molecule . Quaternary structure mainly possible because of cysteine , here disulfide bridge of cysteine cause the linkage of various seprated polypeptides . In quaternary structure of various polypeptide chains are joinded together by interchain disulfide bridge . These interchains of disulfide bridge also provide stability of quaternary structure of proteins . The present of greater number of cysteine amino acids enhance the stablity of proteins molecules .

the atomic number of magnesium is 12. its nucleus must contain 12 protons and no electrons. the atomic number of an atom is determined by the number of protons.

magnesium is an electrolyte injection commonly used to treat low magnesium levels in your blood. it is also used to prevent or control seizures in women with preeclampsia or eclampsia.
