Peptide

Peptides are short chains of amino acids, the building blocks of proteins. Peptides are distinguished from proteins on the basis of size, as a peptide contains less than 50 amino acids. Some examples of peptides include insulin, glutathione, and oxytocin.
How are peptides formed?

Peptides form via:



What are some key functions and uses of peptides?



What is the chemical structure of a peptide?

Structurally, peptides contain a backbone made up of nitrogen (N) and carbon (C) atoms, with side chains of atoms protruding off the N-C backbone. Together, the backbone and amino acid side chains give each peptide a unique 3D shape that relates to its specific function.

While peptides share similarities with proteins, they represent fundamentally simpler molecular structures. This allows them to interact more selectively with biological targets like cell receptors. It also enables easier study, design and manipulation for research or clinical use.

In summary, peptides represent a diverse class of biomolecules with many critical roles in nature. From hormone signaling messengers, to antibiotic defenses, to supplemented nutrition - understanding the chemistry of peptides sheds light on the very building blocks of life. Researchers continue discovering new peptide-based therapies for previously untreatable diseases.
