Correct the following statements by changing the underlined part of the sentence.
Proteins are formed by the `ul("addition polymerization")` of aminoacids.

Explanation

To correct the statement "Proteins are formed by the addition polymerization of amino acids," we need to change the underlined part. Here’s the step-by-step solution:

### Step 1: Understand the Components
- **Proteins**: These are large biomolecules made up of one or more long chains of amino acids.
- **Amino Acids**: The building blocks of proteins, which are linked together to form proteins.

### Step 2: Identify the Type of Polymerization
- **Addition Polymerization**: This type of polymerization involves the direct addition of monomer units without the loss of any small molecules (like water).
