Which of the following are not polymeric?
Explanation: Lipids are not polymers, they are normally esters of fatty acids and alcohol, e.g. triglycerides. Proteins are the polymers of amino acids, nucleic acids are the polymer of nucleotides and polysaccharides are the polymer of monosaccharides.
What macromolecules are not true polymers?
Lipids are the only macromolecules that are not polymers. Lipids are diverse in structure and function, but all have in common that they are hydrophobic—that is, they are nonpolar and do not dissolve in water.
What are the 4 lipid polymers?
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.
Why are lipids not polymers?
Polymers are large molecules made up of repeating subunits called monomers. Lipids are not considered polymers because they do not have true monomers. They do have building blocks called glycerol and fatty acids.
What is not a polymeric compound?
If the forming units of the given biological macromolecules are considered, proteins are formed of amino acids joined one after the other, polysaccharides are formed from monosaccharides, nucleic acids are formed of nucleotides. Only lipids are not made of uniform components, that is, they are not polymeric.
What is not polymer?
Examples of materials which are not polymers include:
- Elements.
- Metals.
- Ionic compounds, such as salt.
Why don t lipids have a true monomer?
Lipids are not true macromolecules because the monomers are not covalently bonded together. Simple lipids are composed of subunits made of fatty acids covalently bonded to a triose sugar – glycerol.
Why lipids are not considered polymers?
Why all macromolecules are not polymer?
The polymers are also called as macromolecules because of their big size. A polymer always consists of thousands of repeating monomers units. However a macromolecule is a giant molecule which may or may not contain monomer units. Thus all the polymers are macromolecules but reverse is not true.
Which class does not consist of polymers?

| what are the four main classes of large biological molecules? Which class does not consist of polymers? | protein, carb, lipid, nucleic acid and lipids are not polymers |
Why are lipids not considered true macromolecules but not polymers?
Carbohydrates, lipids, proteins and nucleic acids are all considered to be macromolecules. However lipids are not considered to be polymers, because lipids do not contain monomers and polymers are made up out of monomers. Similarly one may ask, why are lipids not considered true macromolecules?
Why are carbohydrates not considered to be macromolecules?
Macromolecules are giant molecules that are produced by the bonding of smaller molecules. Carbohydrates, lipids, proteins and nucleic acids are all considered to be macromolecules. However lipids are not considered to be polymers, because lipids do not contain monomers and polymers are made up out of monomers.
How are lipid chains different from polymers chains?
Polymers are the chains where a compound is linked to itself continously . Whereas lipid structure has one carboxyl group and a long hydrocarbon chain which is nonpolar and hence after dehydration forms an ester bond between them .
Which is an example of a lipid bond?
For example, such a lipid is cholesterol. Dehydration is the process of creating a bond between two molecules to create a new, larger molecule by taking one hydrogen from one molecule, and an OH from the other, creating one molecule of free water.
