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 are macromolecules formed quizlet?

Macromolecules are made from thousands/hundred of thousands of smaller molecules(monomers). They are formed by a process called polymerization. Polymerization is the process by which large compounds are built by joining smaller ones together, or monomers coming together to make polymers. Many.

What is the source of macromolecules?

Sources of biological macromolecules: Foods such as bread, fruit, and cheese are rich sources of biological macromolecules. Many critical nutrients are biological macromolecules. The term “macromolecule” was first coined in the 1920s by Nobel laureate Hermann Staudinger.
