• Shoulder.
• Exocarp. The outer skin of the pepper.
• Mesocarp. The fleshier inner skin of the pepper.
• Endocarp. This is the inner portion of the pepper that surrounds the seeds.
• Placenta/Capsaicin Glands. This is where capsaicin is produced, the chemical that makes chili peppers hot. It is often incorrectly reported that chili pepper heat is in the seeds, but this is false.
