What are the 4 subunits of macromolecules?

As we’ve learned, there are four major classes of biological macromolecules:

  • Proteins (polymers of amino acids)
  • Carbohydrates (polymers of sugars)
  • Lipids (polymers of lipid monomers)
  • Nucleic acids (DNA and RNA; polymers of nucleotides)

What are the structures of macromolecules?

Macromolecules are made up of basic molecular units. They include the proteins (polymers of amino acids), nucleic acids (polymers of nucleotides), carbohydrates (polymers of sugars) and lipids (with a variety of modular constituents).

What are the three subunits that make up macromolecules?

We will begin with the monomer units.

  • monosaccharide — for carbohydrate.
  • nucleotide — for nucleic acids.
  • amino acid — for proteins.

What are the structures and functions of the 4 macromolecules?

The four main macromolecules are proteins, carbohydrates, nucleic acids and lipids. They are an important part of the cell and perform essential functions. Proteins are required for growth and maintenance, immunity and also act as enzymes, hormones, etc. Carbohydrates are the main energy source.

What are the 3 parts of each subunit?

DNA is made of smaller subunits called nucleotides. Each nucleotide consists of three components: a five-carbon sugar called deoxyribose, a phosphate group, and a nitrogenous base.

What are the 4 macromolecules and their monomers?

Proteins, carbohydrates, nucleic acids, and lipids are the four major classes of biological macromolecules—large molecules necessary for life that are built from smaller organic molecules. Macromolecules are made up of single units known as monomers that are joined by covalent bonds to form larger polymers.

How does the structure and the function of each macromolecule related?

The Three-Dimensional Structure of Biological Macromolecules Determines How They Function. It is the three-dimensional shape of proteins and nucleic acids that endows them with their biological activities.

What is the subunit for nucleic acids?

​Nucleotide A nucleotide is the basic building block of nucleic acids (RNA and DNA). A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base.

What is the subunit for lipids?

“The subunits of lipids are fats, oils, waxes, sterols and triglycerides. “

What is the subunit of nucleic acids?

Nucleic acids are composed of smaller subunits called nucleotides. A nucleotide is a nucleoside with one or more phosphoryl group by esterlinkage.

How is the structure of macromolecules related to their function?

Which macromolecule is structure a composed of and what is its function?

Types of biological macromolecules

Biological macromolecule Building blocks Functions
Proteins Amino acids Provide cell structure, send chemical signals, speed up chemical reactions, etc
Nucleic acids Nucleotides Store and pass on genetic information

What are the subunits for nucleic acids?

Nucleic acids are composed of smaller subunits called nucleotides. A nucleotide is a nucleoside with one or more phosphoryl group by esterlinkage. When it is in the form of RNA the bases are called adenylate, guanylate, cytidylate, and uridylate.

What are four names of macromolecules?

The four types of macromolecules are nucleic acids, proteins, carbohydrates and lipids. These macromolecules are large molecules that make up most of the bodies of living things. They consist of chains of repeating units, which are known as polymers. Each macromolecule type has its own structure and function:

What are the four main macromolecules?


  • Lipids.
  • Protein.
  • Nucleic acid.
  • What are molecule made of many smaller subunits?

    Macromolecule A large molecule, made up of many smaller building blocks or subunits; the four types are carbs, lipids, proteins, nucleic acid.

    What is macromolucule made up subunits called monosaccharides?

    The subunits that make up carbohydrates are called monosaccharides, or simple sugars. Also, what are each of the macromolecules made of? There are four classes of macromolecules (polysaccharides or carbohydrates, triglycerides or lipids, polypeptides or proteins, and nucleic acids such as DNA & RNA).
