What are macromolecules?

Back

Macromolecules are large, complex molecules that are essential for life. They include carbohydrates, lipids, proteins, and nucleic acids.

Front

What are the four main types of macromolecules?

Back

The four main types of macromolecules are carbohydrates, lipids, proteins, and nucleic acids.

Front

What are lipids?

Back

Lipids are a group of hydrophobic organic compounds, including fats, oils, and waxes, that are used for energy storage and structural functions in cells.

Front

What are carbohydrates?

Back

Carbohydrates are organic compounds made of carbon, hydrogen, and oxygen, and they serve as a primary energy source for living organisms.

Front

What are proteins?

Back

Proteins are macromolecules made up of amino acids that perform a variety of functions in the body, including catalyzing biochemical reactions and providing structural support.

Front

What are nucleic acids?

Back

Nucleic acids, such as DNA and RNA, are macromolecules that store and transmit genetic information.

Front

What are amino acids?

Back

Amino acids are the building blocks of proteins, consisting of a central carbon atom, an amino group, a carboxyl group, and a variable side chain.

Front

What is the function of carbohydrates in living organisms?

Back

Carbohydrates provide energy, serve as structural components, and play roles in cell recognition and signaling.

Front

What is the role of lipids in the cell?

Back

Lipids serve as energy storage, form cell membranes, and act as signaling molecules.

Front

What is the structure of a protein?

Back

Proteins have a complex structure that includes primary (amino acid sequence), secondary (alpha helices and beta sheets), tertiary (3D shape), and quaternary (multiple polypeptide chains) levels.
