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.

The polymer DNA is known as polynucleotide. Each of the monomers that makes up DNA, which are known as nucleotides, consist of a five-carbon sugar called deoxyribose, a nitrogen-containing base which is attached to the sugar and a phosphate group.DNA is made up of four different types of nucleotides. These differ from each other only in the nitrogenous bases.ach of the monomers that makes up DNA, which are known as nucleotides, consist of a five-carbon sugar called deoxyribose, a nitrogen-containing base which is attached to the sugar and a phosphate group.
