Select the correct terms:
Proteins are (polymers / monomers) of amino acids. A common carbohydrate is (sugar / fat). Nucleic acids are composed of (nucleotides / DNA]. Lipids (are / are not) polymers. All of these organic molecules contain (carbon / nitrogen).

Key Concepts

Proteins

Proteins are large, complex molecules that consist of long chains of amino acids linked through peptide bonds. They function as enzymes, structural components, signaling molecules, and perform many other roles essential to life.

Carbohydrates

Carbohydrates are organic compounds that serve primarily as sources of energy and structural materials in organisms. They are composed of sugar units, which can be simple sugars or form more complex structures.

Nucleic Acids

Nucleic acids are biopolymers responsible for storing and transmitting genetic information. They are made up of nucleotide monomers, which assemble into long chains such as DNA and RNA.

Lipids

Lipids are a diverse group of hydrophobic molecules that are not typically formed as polymers. They include fats, oils, and other compounds that are important for energy storage, membrane structure, and signaling.

Polymers and Monomers

In biochemical contexts, polymers refer to large molecules formed by linking repeating subunits called monomers. While proteins and nucleic acids fit this description, lipids usually do not form such polymeric structures.

Organic Molecules

Organic molecules are compounds primarily composed of carbon, along with elements such as hydrogen, oxygen, and nitrogen. These molecules form the basis of living organisms, making up structures and performing vital functions in cells.
