Key Differences
Polymers are macromolecules composed of smaller, repeating structures known as monomers. Biopolymers, on the other hand, are polymers produced by living organisms and include proteins, nucleic acids, and polysaccharides.
The origin of polymers can be both natural and synthetic, such as plastics. Biopolymers always have a biological origin, ensuring their compatibility with living systems.
While many polymers, especially synthetic ones, can persist in the environment, biopolymers typically degrade more quickly and are often biodegradable, aligning with ecological considerations.
The versatility of polymers allows them to be used in countless applications, from packaging to electronics. Biopolymers, given their natural origin, often serve specific biological functions or are utilized in green, sustainable applications.
Polymers have revolutionized industries, leading to the development of lightweight, durable materials. Biopolymers, capturing scientific interest, promise eco-friendliness and a reduction in pollution, presenting a sustainable alternative to traditional polymers.

Polymer
A polymer (; Greek poly-, "many" + -mer, "part") is a substance or material consisting of very large molecules, or macromolecules, composed of many repeating subunits. Due to their broad spectrum of properties, both synthetic and natural polymers play essential and ubiquitous roles in everyday life.
Biopolymer
A macromolecule in a living organism that is formed by linking together several smaller molecules, as a protein from amino acids or DNA from nucleotides.
Polymer
Any of numerous natural and synthetic compounds of usually high molecular weight consisting of up to millions of repeated linked units, each a relatively light and simple molecule.
Biopolymer
(biochemistry) Any macromolecule of a living organism that is formed from the polymerization of smaller entities; a polymer that occurs in a living organism or results from life.
Polymer
(organic chemistry) A long or larger molecule consisting of a chain or network of many repeating units, formed by chemically bonding together many identical or similar small molecules called monomers. A polymer is formed by polymerization, the joining of many monomer molecules.
Polymer
A material consisting of such polymer molecules.
Polymer
Any one of two or more substances related to each other by polymerism; specifically, a substance produced from another substance by chemical polymerization.
Polymer
A naturally occurring or synthetic compound consisting of large molecules made up of a linked series of repeated simple monomers
