🧬 **Amino Acids: Introduction**: Amino acids are **organic compounds containing both amino (–NH₂) and carboxyl (–COOH) groups**. They are the fundamental **building blocks of proteins** and are linked together by **peptide bonds** to form polypeptide chains. Most protein-forming amino acids are **α-amino acids**, where the amino and carboxyl groups are attached to the same carbon atom.

📌 **Key Points:**
• Functional groups: **–NH₂ and –COOH**
• Building blocks of: **Proteins**
• Linkage between amino acids: **Peptide bond**
• Common general structure: **H₂N–CH(R)–COOH**
• Protein-forming amino acids are mainly **α-amino acids**

🔑 **Remember:**
**Amino acids → Peptide bonds → Polypeptide → Protein**

Refraction of Waves | Study Notes

When a wave travels from one medium to another, its speed and wavelength change, causing the wave to change its direction. This phenomenon is called refraction of waves. 📚⚡

🔹 Frequency remains constant
🔹 Speed changes
🔹 Wavelength changes
🔹 Direction changes when the wave enters obliquely
