How are monomers, polymers, and macromolecules related to each other? | Socratic
Proteins and nucleic acids are two examples of polymers. These giant molecules are also called macromolecules. While there is variation among the types of biological polymers found in different organisms, the chemical. A macromolecule is a very large molecule, such as protein, commonly created by the Usage of the term to describe large molecules varies among the disciplines . The structure of simple macromolecules, such as homopolymers, may be. in relation to biological polymers, a short section discussing Stokes' law of . Macromolecules were recognized only after much fierce struggle among chemists.
Protein is a Macromolecule Here, some macromolecules are multiples of a repeating unit monomerand they are the polymers.
Carbohydrates, proteins, and lipids contain monomers. However, we cannot sub-divide some macromolecules into individual entities; some of those molecules have macrocycles. For example, fat is a macromolecule synthesized by condensation of four molecules glycerol and 3- fatty acidsbut it is not a polymer.

Macromolecule and polymer are both giant molecules. However, not all macromolecules are polymers. Because, we cannot divide some of them into small units.
That is, not every macromolecule has a monomer in their structure. Hence, the key difference between polymer and macromolecule is that the polymer is a macromolecule with a repeating unit called monomer throughout the molecular structure whereas, not every macromolecule has a monomer in their structure.
Also, another difference between polymer and macromolecule is that the macromolecules comprise both polymeric and non-polymeric molecules, but polymers include only polymerized molecules. The below infographic presents difference between polymer and macromolecule in tabular form.Monomers vs Polymers - Biology Tutorial
Therefore, molecular weight is the factor that matters in macromolecule. Second, DNA has a much greater stability against breakdown than does RNA, an attribute primarily associated with the absence of the 2'-hydroxyl group within every nucleotide of DNA.

Third, highly sophisticated DNA surveillance and repair systems are present which monitor damage to the DNA and repair the sequence when necessary. Analogous systems have not evolved for repairing damaged RNA molecules.
Consequently, chromosomes can contain many billions of atoms, arranged in a specific chemical structure. Proteins are optimised for catalysis[ edit ] Proteins are functional macromolecules responsible for catalysing the biochemical reactions that sustain life.

In addition, the chemical diversity of the different amino acids, together with different chemical environments afforded by local 3D structure, enables many proteins to act as enzymescatalyzing a wide range of specific biochemical transformations within cells. In addition, proteins have evolved the ability to bind a wide range of cofactors and coenzymessmaller molecules that can endow the protein with specific activities beyond those associated with the polypeptide chain alone.
RNA encodes genetic information that can be translated into the amino acid sequence of proteins, as evidenced by the messenger RNA molecules present within every cell, and the RNA genomes of a large number of viruses. The single-stranded nature of RNA, together with tendency for rapid breakdown and a lack of repair systems means that RNA is not so well suited for the long-term storage of genetic information as is DNA.

In addition, RNA is a single-stranded polymer that can, like proteins, fold into a very large number of three-dimensional structures. Some of these structures provide binding sites for other molecules and chemically-active centers that can catalyze specific chemical reactions on those bound molecules.
