What are the 4 macromolecules and their functions?
- Nucleic acids: Stores and transfers info.
- Carbohydrates; Store energy, provide fuel, and build structure in body, main source of energy, structure of plant cell wall.
- Lipid: Insulator and stores fat and energy.
- Protein: Provide structural support,transport, enzymes, movement, defense.
What are the 4 types of macromolecules and their monomers?
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 some examples of each of the four macromolecules?
Types of biological macromolecules
| Biological macromolecule | Building blocks | Examples |
|---|---|---|
| Lipids | Fatty acids and glycerol | Fats, phospholipids, waxes, oils, grease, steroids |
| Proteins | Amino acids | Keratin (found in hair and nails), hormones, enzymes, antibodies |
| Nucleic acids | Nucleotides | DNA, RNA |
What is the function of each macromolecule?
Hear this out loudPauseFor example, macromolecules provide structural support, a source of stored fuel, the ability to store and retrieve genetic information, and the ability to speed biochemical reactions. Four major types of macromolecules—proteins, carbohydrates, nucleic acids, and lipids—play these important roles in the life of a cell.
What are the building blocks of Carbohydrates?
Hear this out loudPauseMonosaccharides. Monosaccharides include glucose, galactose and fructose – all commonly found in food. Monosaccharides are single sugar molecules that are the building blocks for all other sugars and carbohydrates.
Which of the four macromolecules is the most important?
Hear this out loudPauseProteins. After nucleic acids, proteins are the most important macromolecules. Structurally, proteins are the most complex macromolecules. A protein is a linear molecule comprised of amino acids.
What are the four major classes of macromolecules?
In Summary: Different Types of Biological Macromolecules. 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.
What makes up the DNA of a macromolecule?
Each macromolecule type has its own structure and function: Nucleic acids are DNA and RNA. DNA contains the genetic components and instructions in a cell, while RNA is used by the cell to make proteins. They consist of nucleotide polymers: adenosine, guanine, cytosine, uracil and thymine.
What are some examples of macromolecules used in everyday life?
Nylon, Polyester, and acrylic fibres are used in everything from blouses, belts to shirts and shoes. Natural fibres include wool, wool, cotton, and silk. Hence, there are many objects that we use today are made up of macromolecules.
Which is an example of a chemical reaction in a macromolecule?
These reactions are similar for most macromolecules, but each monomer and polymer reaction is specific for its class. For example, in our bodies, food is hydrolyzed, or broken down, into smaller molecules by catalytic enzymes in the digestive system. This allows for easy absorption of nutrients by cells in the intestine.
