Simply explained:
How are peptides formed?
When two or more amino acids are linked together by a peptide bond, a peptide is formed.
Why are peptides important?
Peptides play many important roles in the human body:

Simply explained:
- Amino acids = letters
- Peptides = words
- Proteins = full sentences
How are peptides formed?
When two or more amino acids are linked together by a peptide bond, a peptide is formed.
- 2 amino acids → dipeptide
- Several amino acids → oligopeptide
- Very long chain → protein
Why are peptides important?
Peptides play many important roles in the human body:
Act as hormones (for example, insulin)
Serve as signaling molecules between cells
Support muscle growth and recovery
In cosmetics, they help stimulate collagen production
Used in medicine and pharmaceuticals
