DIETARY IMPACTS OF ASTRONAUTS' BONES
 
Chemistry

Key Topics: Stoichiometry, Acid-Base Reaction

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. This activity will have students analyze the chemical reaction that occurs in the bone between sulfuric acid and Calcium carbonate and propose a possible avenue for astronauts to decrease bone mineral loss.

Students will
  • determine mass and volume relationship with an emphasis on mole concepts; and
  • write acid-base reactions.
