antioxidant. 1  Chemistry. any substance that inhibits oxidation, as a substance that inhibits oxidative deterioration of gasoline, rubbers, plastics, soaps, etc. 2  Biochemistry. an enzyme or other organic substance, as vitamin E or beta carotene, that is capable of counteracting the damaging effects of oxidation in animal tissues.
Amino acids are natural monomers that polymerize at ribosomes to form proteins. Nucleotides, monomers found in the cell nucleus, polymerize to form nucleic acids â DNA and RNA.Glucose monomers can polymerize to form starches, glycogen or cellulose; xylose monomers can polymerise to form xylan.ucleotides, monomers found in the cell nucleus, polymerize to form nucleic acids â DNA and RNA.

How it is Made. This substance is categorized as a polymer â a molecule that consists of a series of repeating smaller units called monomers â based on its chemical structure. It is manufactured by combining two types of compounds, a diisocyanate and a diol, which are monomers, through a chemical reaction.
