Review for 7C Biomolecule Flashcard

Front

What is a triglyceride?

Back

A triglyceride is a type of lipid made up of three fatty acids attached to a glycerol molecule. It is a major form of stored energy in the body.

Front

What are amino acids?

Back

Amino acids are organic compounds that serve as the building blocks of proteins. They contain an amino group, a carboxyl group, and a unique side chain.

Front

What are monosaccharides?

Back

Monosaccharides are the simplest form of carbohydrates, consisting of single sugar molecules like glucose and fructose.

Front

What is cellulose?

Back

Cellulose is a complex carbohydrate (polysaccharide) that forms the structural component of plant cell walls. It is not digestible by humans.

Front

What is a carbohydrate?

Back

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

Front

What is the role of lipids in the body?

Back

Lipids, including triglycerides, serve as long-term energy storage, insulation, and make up cell membranes.

Front

What is the difference between a polymer and a monomer?

Back

A polymer is a large molecule made up of repeating subunits called monomers. For example, proteins are polymers made of amino acid monomers.

Front

What are the four main types of biomolecules?

Back

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

Front

What is the function of proteins in the body?

Back

Proteins perform a variety of functions including catalyzing biochemical reactions (enzymes), providing structure, and facilitating communication between cells.

Front

What is a polypeptide?

Back

A polypeptide is a chain of amino acids linked by peptide bonds, which folds into a functional protein.
