Linear Peptide
Linear Peptide — A peptide with a straight-chain structure where the amino acid sequence runs from N-terminus to C-terminus without cyclization.
What Is a Linear Peptide?
A linear peptide has no intramolecular covalent bonds connecting non-adjacent residues; the chain extends from N-terminus to C-terminus without rings or branches. Most synthetic peptides are linear by default. Linear peptides are simpler to synthesize than cyclic or branched peptides but have greater conformational flexibility and protease susceptibility.
Linear vs. Cyclic
- Flexibility: Linear peptides sample many conformations (entropy penalty upon binding)
- Protease: Both termini exposed to exopeptidases. Shorter half-life
- Synthesis: Standard SPPS. No cyclization step needed
