What is a monomer unit?

A monomer is the basic unit that binds chemically to other molecules to form a polymer. For lipids, the monomers are glycerol and fatty acids. For proteins, the monomers are amino acids. For nucleic acids, the monomers are nucleotides which is made of a pentose sugar, a nitrogenous base and a phosphate group.

In this way, do lipids have monomers?

Unlike other biomolecule groups, fatty acid monomers are not directly bonded to each other in polymer chains. Dehydration synthesis reactions in lipids form an ester linkage between the carboxyl group of a fatty acid and the hydroxyl group of an alcohol monomer such as glycerol.

What are the monomers and polymers of a lipid?

Types of Organic MoleculesMonomersPolymers
CarbohydratesSimple Carbohydrates or monocarbohydrates (glucose)Complex Carbohydrate or polycarbohydrates (starch)
LipidsFatty acidsSaturated fats Polyunsaturated fats
Amino AcidsAmino AcidsPeptides & Proteins
Nucleic AcidsNucleic AcidsDNA & RNA

What is the monomer unit of a protein?

Amino acids are natural monomers that polymerize at ribosomes to form proteins. Nucleotides, monomers found in the cell nucleus, polymerize to form nucleic acids – DNA and RNA.
