Which monomers go with which polymers?
Examples of biological monomers and polymers:
| Polymers | Monomers |
|---|---|
| Polysaccharides | Monosaccharides (simple sugars) |
| Polypeptides and proteins | Amino-acids |
| Nucleic acids | Nucleotides |
What is the process by which monomers are linked together to form polymers?
Dehydration Synthesis The monomers combine with each other using covalent bonds to form larger molecules known as polymers. In doing so, monomers release water molecules as byproducts. This type of reaction is known as dehydration synthesis, which means “to put together while losing water.”
What is the relationship between a polymer and a monomer?
All monomers have the capacity to form chemical bonds to at least two other monomer molecules. Polymers are a class of synthetic substances composed of multiples of simpler units called monomers. Polymers are chains with an unspecified number of monomeric units.
What is it called when two or more monomers are joined together?
The process for connecting two monomers together (forming a covalent bond) is called dehydration synthesis.
What are the 4 major macromolecules?
There are four major classes of biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids), and each is an important component of the cell and performs a wide array of functions. Combined, these molecules make up the majority of a cell’s mass.
How polymers are broken down?
Polymers are broken down into monomers via hydrolysis reactions, in which a bond is broken, or lysed, by addition of a water molecule. This is the reverse of a dehydration synthesis reaction, and it releases a monomer that can be used in building a new polymer.
Why proteins are called biological polymer?
Proteins are the macromolecules which are made from the amino acids when joined together by peptide bonds. Amino acids are polymers which are used to build tissues and other components of living organisms. Thus, they are called biological polymers.
How do polymers work?
When many molecules of a simple compound join together, the product is termed a polymer and the process polymerization. The simple compounds whose molecules join together to form the polymers are called monomers. The polymer is a chain of atoms, providing a backbone, to which atoms or groups of atoms are joined.
Is DNA a polymer?
DNA consists of two long polymers (called strands) that run in opposite directions and form the regular geometry of the double helix. The monomers of DNA are called nucleotides. Nucleotides have three components: a base, a sugar (deoxyribose) and a phosphate residue.
Why DNA is a polymer?
DNA is a polymer due to the fact it contains multiple repeating units (monomers). These monomers are known as nucleotides. Multiple nucleotides join together by phosphodiester bonds to form the polymer that is DNA.
What exactly is a polymer?
Polymer, any of a class of natural or synthetic substances composed of very large molecules, called macromolecules, that are multiples of simpler chemical units called monomers. Polymers make up many of the materials in living organisms, including, for example, proteins, cellulose, and nucleic acids.
What type of polymer is DNA?
polynucleotide
What are polymers give examples?
Examples of synthetic polymers include nylon, polyethylene, polyester, Teflon, and epoxy. Natural polymers occur in nature and can be extracted. They are often water-based. Examples of naturally occurring polymers are silk, wool, DNA, cellulose and proteins.
Is a steroid a polymer?
Steroids are not considered true lipid polymers because their molecules do not form a fatty acid chain. Instead, steroids are composed of four fused carbon ring-like structures.
Are waxes polymers?
Polymer waxes are typically manmade ingredients which simulate the same properties as a natural wax. They do not offer the same luster as a carnauba wax. However, car enthusiasts find that they are easier to work with in terms of application and buffing.
How long does polymer wax last?
12 months

Is oil a monomer or polymer?
Vegetable oils in general are cationically polymerizable monomers, because their branched triglyceride structure leads to extensive crosslinking. Each unsaturated fatty acid chain in the triglyceride structure can participate in the cationic reaction.
Is amino acid a monomer or polymer?
Groups of Monomers and Polymers Proteins – polymers are known as polypeptides; monomers are amino acids. Nucleic Acids – polymers are DNA and RNA; monomers are nucleotides, which are in turn consist of a nitrogenous base, pentose sugar, and phosphate group.
Is hemoglobin a monomer or polymer?
Why is hemoglobin a tetramer protein but not trimer/dimer or monomer? Hemoglobin is tetramer but myoglobin as a similar protein is monomer.
What type of polymer is hemoglobin?
globular transport protein
Is myoglobin a dimeric?
Abstract. Myoglobin (Mb) stores dioxygen in muscles, and is a fundamental model protein widely used in molecular design. The presence of dimeric Mb has been known for more than forty years, but its structural and oxygen binding properties remain unknown.
Is hemoglobin A monomer?
Haemoglobin, like myoglobin is an oxygen-binding protein. Whereas myoglobin exists as a monomer, haemoglobin is a tetramer: each of the four subunits is similar in terms of fold to myoglobin. As haemoglobin binds successive oxygens, the oxygen affinity of the subunits increases.
What are the 4 types of hemoglobin?
The chemical state of hemoglobin changes sequentially over the first two weeks as a hematoma evolves. Four different hemoglobin species are commonly recognized: oxyhemoglobin (oxy-Hb), deoxyhemoglobin (deoxy-Hb), methemoglobin (met-Hb), and hemichromes, whose structures appear below.
What are the 4 subunits of hemoglobin?
Hemoglobin is a protein made up of four polypeptide chains (α1, α2, β1, and β2). Each chain is attached to a heme group composed of porphyrin (an organic ringlike compound) attached to an iron atom.
What are the two conformations of hemoglobin?
What are the two conformations of hemoglobin? The T state (the conformation of deoxyhemoglobin) and the R state (the conformation of oxyhemoglobin).
