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.

Proteins (also known as polypeptides) are organic compounds made of amino acids arranged in a linear chain and folded into a globular form. The amino acids in a polymer are jo â¦ ined together by the peptide bonds between the carboxyl and amino groups of adjacent amino acid residues.roteins are made out of 20 smaller sub-units called amino acids. these acids contain four chemical elements: carbon, hydrogen, oxygen and nitrogen.
