Aragonite is a polymorph of calcite, a mineral that has the same chemical composition as calcite, but has a slightly different crystal structure. For most purposes aragonite and calcite can be considered to be the same mineral. In its crystal form, aragonite tends to have needlelike crystals and lacks calcite's rhombohedral cleavage.

Sulfur is an essential element of life in sulfurcontaining proteins. Elemental Sulfur Rhombic and monoclinic sulfur are known as allotropes. The crystals of these have the molecules S 8. In these molecules, S form two SS bonds. The lone pairs of electrons make the SSS bend (108 deg), resulting in S 8 having the shape of a crown.

Sulfur bonds are required for proteins to maintain their shape, and these bonds determine the biological activity of the proteins. For example, hair and nails consist of a tough protein called keratin, which is high in sulfur, whereas connective tissue and cartilage contain proteins with flexible sulfur bonds, giving the structure its flexibility.
