In IUPAC nomenclature, however, hexane is the unbranched isomer (n-hexane); the other four isomers are named as methylated derivatives of pentane and butane. IUPAC also uses the term as the root of many compounds with a linear six-carbon backbone, such as 2-methylhexane (C7H16), which is also called isoheptane.
Dentin is the substance between enamel or cementum and the pulp chamber. It is secreted by the odontoblasts of the dental pulp. The formation of dentin is known as dentinogenesis. The porous, yellow-hued material is made up of 70% inorganic materials, 20% organic materials, and 10% water by weight.
On the very outside of your teeth is something called enamel. Enamel is the hardest material in the entire body ! Below the enamel is a part of the tooth known as the dentin, which is mostly made up of hard minerals like calcium. (You might know calcium as the good-for-you ingredient that gives milk its white color.).n the very outside of your teeth is something called enamel.
