The Chemistry Involved in Bone Loss (TI-Nspire™)
 
Chemistry

Key Topic: Acid Reactions

Recently the Nutritional Biochemistry Laboratory has been exploring the amino acids in animal proteins and their affect on the Calcium metabolism. Amino acids containing sulfur can create sulfuric acid in the body, which can cause an increase in calcium metabolism. In this activity, students will look at the reaction between sulfuric acid and Calcium carbonate, the chemical that makes up bones. They will determine the amount of acid that is needed to breakdown 1% of the total bone mass of a human and whether it is feasible that enough acid can be produced from the metabolism of sulfur containing amino acids.

Students will
  • balance reactions with carbonates;
  • calculate the number of moles of carbon dioxide released using the ideal gas law;
  • use stoichiometry to determine the mass of calcium removed in a reaction; and
  • calculate the number of moles of lost calcium.
