A polypeptide is composed of monomers called <em>amino acids</em> . Nucleic acids are composed of monomers called <em>nucleotides</em> . Triglycerides are composed of glycerol and <em>fatty acids</em> . Glucose, starch, and cellulose are all examples of <em>carbohydrates</em> . RNA and DNA are examples of <em>nucleic acids</em> . Fats, steroids, and terpenes are examples of <em>lipids</em> . Polymers are formed by linking monomers together through <em>chemical</em> reactions. Breaking the bonds between the subunits of a polymer involves <em>catabolic</em> reactions. During a hydrolysis reaction, a molecule of water is <em>consumed</em> . During a condensation reaction, a molecule of water is <em>formed.</em>
