What is the polymer of proteins examples?
Myoglobin and hemoglobin are important examples of the class of compounds known as proteins, which are linear polymers of between 40 and 10,000 (or more) amino acids.
Does protein have polymer?
Proteins are polymers in which the 20 natural amino acids are linked by amide bonds.
What type of polymers are proteins made of?
Proteins are natural polymers made up of amino acids, and nucleic acids (DNA and RNA) are polymers of nucleotides — complex molecules composed of nitrogen-containing bases, sugars and phosphoric acid, for example.
What are 4 types of polymers?

Why are proteins a polymer?
1 Answer. A polymer is made up of multiple sub units tied together. A protein is made up of multiple subunits called amino acids.
What is monomer and polymer of proteins?
The building blocks of proteins are amino acids, which contain elements such as H,N,O,C, and more. They are the monomers of the proteins. So, the monomer will be the amino acids, and the polymer will be the proteins themselves.
What is polymers of amino acids?
Proteins are the polymers of amino acids.
What are the 3 main types of polymers?
There are 3 principal classes of polymers – thermoplastics, thermosets, and elastomers. Differentiation between these classes is best defined by their behaviour under applied heat. Thermoplastic polymers can be either amorphous or crystalline. They behave in a relatively ductile manner but often have low strength.
What is the name of its polymer?
Answer. 1 ) Natural polymers occur in nature and can be extracted. They are often water-based. 2)This polymer is called polyethylene rather than polymethylene, (-CH2-)n, because ethylene is a stable compound (methylene is not), and it also serves as the synthetic precursor of the polymer.
What are polymers of lipids?
Lipids: water-insoluble molecules that can be classified as fats, phospholipids, waxes, and steroids. Fatty acids are lipid monomers that consist of a hydrocarbon chain with a carboxyl group attached at the end. Fatty acids form complex polymers such as triglycerides, phospholipids, and waxes.
What is the monomer of proteins?
For example, proteins are composed of monomers called amino acids. They are linked together to form a polypeptide chain, which folds into a three dimensional (3D) structure to constitute a functional protein (Figure 1).
What are the main polymers?
These include cellulose, lignin, and various resins. Cellulose is a polysaccharide, a polymer that is composed of sugar molecules. Lignin consists of a complicated three-dimensional network of polymers. Wood resins are polymers of a simple hydrocarbon, isoprene.
Is RNA a polymer?
RNA is a linear polymer of nucleotides linked by a ribose-phosphate backbone.
How are protein polymers formed?
Proteins are natural condensation polymers formed by joining together thousands of amino acid molecules. Amino acid molecules have two functional groups – the amine group (-NH 2) and a carboxyl group (-COOH).
Why proteins are polymers of amino acids?
Proteins consist of amino acids conjugated by peptide bonds, which is a type of amide bond formed from a carboxyl group and an amino group in α-amino acids (except for one case). This special type of amide bond is called as a peptide bond and the large molecules (polymers) thus obtained are polypeptides.
What are the 3 monomers of proteins?
Comparing the Biological Macromolecules
|Basic Formula, key features
|CHON −NH2 + −COOH +R group
|C:H:O Greater than 2:1 H:O (carboxyl group)
|Fatty acid and glycerol
|CHONP pentose, nitrogenous base, phosphate
What is a polymer vs 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 the polymer of nucleic acids?
Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are polymers composed of monomers called nucleotides. An RNA nucleotide consists of a five-carbon sugar phosphate linked to one of four nucleic acid bases: guanine (G), cytosine (C), adenine (A) and uracil (U).
What is the polymer of carbohydrates?
The polymers of carbohydrates are disaccharides and polysaccharides that consist of two or more monomers respectively. Examples of monosaccharide are: glucose, fructose and galactose. Examples of disaccharides are: sucrose, lactose and maltose.
What are polymers of glucose?
Polymers of glucose are known as the glucans. These glucans are types of homopolysaccharides. Amylose, cellulose, and glycogen are examples of polymers of glucose.
