For some people an insufficiency in normal hydrochloric acid in the body can be a factor in the development of bone loss since if digestion is incomplete, bone building minerals are not going to be absorbed as they should. THE BONES ARE FLEXIBLE BECAUSE VITAMIN D ALLOWS CALCIUM TO BE DEPOSITED INTO THE BONE MATRIX CORRECTLY. There are two categories of decalcifying agents namely, chelating agents and acids. Leave the container in a warm location where you won't mind the smell. Fracture Properties of Chicken Bones in Hydrochloric Acid: Three Point Bending Test .

Strong acids such as hydrochloric or nitric acid at concentrations up to 10% are the most rapid in action but if used for an excessive time will rapidly cause a loss of nuclear staining and can macerate tissues. Hydrochloric acid (HCL) is a colorless and highly pungent solution of hydrogen chloride and water. We observed a division of the cortical bone cross section into three distinctive zones: demineralized matrix (DM) in the periosteal part of bone, middle contact zone (CZ), and mineralized matrix (MM) in the endosteal part of bone.
