years ago humans used calcium-based lime as a
building material. The element calcium is soft
compared to most other metals, but it often bonds
with carbon and oxygen to form calcium carbonate
(CaCO3), a primary component of durable materials
like limestone, marble, and concrete.
The calcium compounds formed in many animals
become the defining physical structures that
support body weight and enable critical functions
like movement and eating. There are 206
calcium-rich bones in a typical adult human
skeleton, the largest of which is the femur.

HEME B STRUCTURE
Hemoglobin is a protein found in the red blood cells
of most vertebrates. It is responsible for transporting oxygen throughout the body. Hydrogen, carbon,
oxygen, and nitrogen atoms form around an iron
ion to compose the heme B enzyme abundant in
human hemoglobin.
