Did you know?
Dibenzothiophene (DBT, diphenylene sulfide) is the organosulfur compound consisting of two benzene rings fused to a central thiophene ring. It is a colourless solid that is chemically somewhat similar to anthracene. This tricyclic heterocycle, and especially its alkyl substituted derivatives, occur widely in heavier fractions of petroleum. WebJun 25, 2024 · Key Points. Hair is made up of keratin protein. Protein is formed by the polymerization of amino acids. Keratin structure is stabilized by various chemical bonds, e.g. peptide bond, disulfide bond, ionic bonds, and Van der Waals. The disulfide is the strongest and most important chemical bond in hair structure.
