A biomineral is a mineral that is produced by a living organism. The term usually refers to inorganic materials such as bones, teeth, and shells, but it can also include some organic materials such as coral. Biominerals are often very hard and resistant to erosion, making them valuable resources for humans. Some of the most well-known biominerals include calcium carbonate (limestone), silica (quartz), and apatite (bone phosphate).

Biominerals are formed through a process called biomineralization. This involves the deposition of minerals by cells within the organism. The cells use special proteins called “mineralizing proteins” to create the desired mineral structure. These proteins can control the shape, size, and composition of the biomineral.

Biominerals have a number of important functions in organisms. They can provide structure and strength to tissues, help regulate pH, store energy, and protect against infection. Biominerals are also often used for camouflage or communication purposes.

The study of biominerals is an important area of research, as they can provide insights into the biology and evolution of organisms. Additionally, biominerals may have applications in fields such as medicine and engineering.

Biominerals are often very hard and durable, making them valuable materials for use in things like jewelry and construction. They can also be used in medical applications, such as implants and prostheses.

The ability of organisms to produce minerals is an evolutionary adaptation that helps them survive in their environment. For example, the hard shells of mollusks help protect them from predators and parasites. The sharp claws of tigers help them catch prey.
