Infographic on what bones are made of. Bone is a composite of collagen protein and hydroxyapatite mineral. Bone marrow is made up of mostly fats and water. Bone marrow is either red marrow, which makes blood cells, or yellow marrow, which stores fats. When we are born, all our bone marrow is red, but it gradually converts into yellow marrow as we age.
