WebOct 13, 2024 · Even the DNA in your cells is a polymer. By definition, polymers are large molecules made by bonding (chemically linking) a series of building blocks. The word polymer comes from the Greek words for “many parts.”. Each of those parts is scientists call a monomer (which in Greek means “one part”). WebJan 25, 2024 · A polymer is a material formed by several minor molecules joined together via a chemical bond to create a larger molecule. The chemical bonds in biomolecules can be divided into two parts namely, primary and secondary bonds. Primary bonds are formed due to sharing of electrons.
WebGlucose and galactose are stereoisomers of each other: their atoms are bonded together in the same order, but they have a different 3D organization of atoms around one of their asymmetric carbons.
