The major type of biological molecules that does not consist of monomers and polymers are Lipids. Although triglycerides are created by the combination of similar molecules, others, steroids, are not.
That is the lipids. They contain fatty acids and glycerol
There is only one. That are the lipids
They are formed from the products (i.e alkenes and alkanes) of the fractional distillation of crude oil. Alkenes and alkanes are hydrocarbons - their molecules consist of hydrogen and carbon only. Monomers of these substances bond to form long chains called polymers. Polymers are what make up plastics.
Lipids are not polymers but are macromolecules. So we cannot speak of monomers and polymers of lipids.Lipids are triglycerides, the simplest form being formed by a condensation reaction between a molecule of glycerol (which has 3 -OH groups) and 3 fatty acids.
monomer = amino acidpolymer = polypeptide (= polypeptide chain)A monomer is one unit in a chain of repeating units. Amino acids are assembled in cells into chains called polypeptides.A protein may consist of just one polypeptide, or more than one. For example, human growth hormone has only one chain, but hemoglobin has four.
Sugars have hydroxyl groups on most of their carbon atoms. Linkage between molecules can therefore happen using different hydroxyl groups.
All compounds consist of molecules.

Many polymers consist of a single kind of monomer that repeats over again multiple times.
The monomers of nucleic acids are called nucleotides. There are only two types of nucleic acid: RNA and DNA. Both nucleotides contain a ribose sugar, a phosphate, and a nitrogenous base.
A polymer (a chemical term) is any material that is made up of repeating linked units (monomers). An example of a polymer is starch. It is made from linked units of Glucose (a sugar). Another example is plastics such as low density polyethylene made from linking repeating ethylene (a gas) units. Maybe a more familar example that is used around the house is when you repair your car with fiberglass. The liquid that is used to bond the fiberglass to the car and itself is styene monomer. When the catalyst is added to the styrene monomomer you are starting a chemical reaction that joins the monomers into very long polymers that cross link and form a hard polymer.

The basic building block for a polymer is a monomer which are rather smaller than the resultant polymer.
Lipids are macromolecules that aren't polymers, as their structure does not consist of a repeating chain of monomers. Proteins, carbohydrates and nucleic acids are all macromolecules and polymers.
It woule be more accurate to say that polysaccharides are polymers.
I hope this helps: Polymer (monomer,subunit) (a) Many macromolecules consist of polymers (b) A polymer is a large molecule built up from smaller building block molecules (c) Monomers (a.k.a., subunits) are the building block molecules (d) "The inherent differences between human siblings reflect variations in polymers, particularly DNA and proteins. Molecular differences between unrelated individuals are more extensive, and between species greater still . . . The molecular logic of life is simple but elegant: Small molecules common to all organisms are ordered into unique macromolecules . . . For each class (of compound) we will see that the macromolecules have emergent properties not found in their individual monomers
Proteins are polymers made up of amino acid monomers. Any chain of two or more amino acids is called a peptide. When many amino acids are joined together, the result is called a polypeptide, or a protein.

The monomers of DNA are nucleotides, which consist of the sugar deoxyribose, a phosphate group, and a nitrogen base.
