a polymer of one or more types of repeating units
In a living organism, any large molecule (such as a protein, nucleic acid, lipid, or polysaccharide) made from smaller parts.
Any polymer (a long repeating chain of atoms) found in nature. Examples include starch, proteins and DNA.
Any large molecule in an organism that is made up of a repeating number of smaller components. Examples include proteins (made up of amino acids), starch and cellulose (made up of sugars) and DNA (made up of nucleic acids).
Any large polymeric molecule (protein, nucleic acid, polysaccharide, lipid) produced by a living organism.
Biopolymers are a special class of polymers produced by living organisms. Starch, proteins and peptides, DNA, and RNA are all examples of biopolymers, in which the monomer units, respectively, are sugars, amino acids, and nucleic acids.
