The sequence in which `alpha`-amino acids are linked to each other through...............bonds determine the.............structure of proteins.

Explanation

To solve the question, we need to identify the types of bonds that link alpha-amino acids and the specific structure of proteins that is determined by this sequence.

### Step-by-Step Solution:

1. **Identify the Bonds**: The alpha-amino acids are linked together by specific types of bonds. In proteins, these bonds are known as **peptide bonds**. Peptide bonds form between the carboxyl group of one amino acid and the amino group of another, releasing a molecule of water in the process (a condensation reaction).

2. **Determine the Structure**: The sequence of amino acids linked by peptide bonds defines the **primary structure** of a protein. The primary structure is essentially the linear sequence of amino acids in a polypeptide chain.
