### Protein Structure and Heat Denaturation

**16) Why does heat denature a protein?**

*Heat can disrupt the hydrogen bonds, ionic bonds, and other forces that maintain the protein's three-dimensional structure, causing it to unfold and lose its functional shape.*

---

### Peptide and Protein Structure

**17) Draw a dipeptide composed of glycine and alanine.**

*A dipeptide consists of two amino acids linked by a single peptide bond. Glycine and alanine can be represented with their chemical structures, showing the connection between the amino group of glycine and the carboxyl group of alanine.*

---

### Protein Secondary Structures

**18) Draw a general sketch of an alpha-helix and a beta-sheet.**

*An alpha-helix is a right-handed coil, formed by hydrogen bonds between every fourth amino acid. A beta-sheet consists of beta strands connected laterally by at least two or three backbone hydrogen bonds, forming a sheet-like structure.*
