BCP 102 GD: Bones 4 (A-E)

The crystal that makes bone hard is:

The chemical formula for the bone crystal is Ca5(PO4)3(OH).

Phosphate, PO4, is a critical component of the bone crystal.

Phosphorolationase is used for smoke bombs in the military because it emits so much smoke. It’s been also used in grenades and in bombs.

A bone osteon is about the size of the upper eyebrow.

Lamellae rings in the osteons grow in rings like tree rings. There can be 20 or more of these rings in each osteon.

To make compact bone, collagen molecules are put into place side-by-side like railroad tracks by the osteoblasts.

The 3 nm bone crystal that is laid down in the collagen matrix in bone is regulated in size by citrate which is poured all over the crystal like syrup on a pancake.

The genetic code of people contains roughly 30,000 protein-coding parts.

Our DNA builds 500,000 miles of blood vessels as well as the same amount for nerves.
