Custom peptides play a crucial role in pharmaceutical research, particularly in drug discovery. Scientists use them to:

– Study protein-protein interactions
– Develop peptide-based therapeutics
– Create inhibitors for specific biological targets
– Design vaccines and immunotherapies

### Structural Biology Studies

Researchers employ custom peptides to:

– Investigate protein folding mechanisms
– Study enzyme-substrate interactions
– Analyze binding domains of proteins
– Develop models for protein structure prediction

## Advantages of Using Custom Peptides

Custom peptides offer several benefits for research applications:

– High purity and specificity
– Tailored modifications (phosphorylation, acetylation, etc.)
– Precise control over amino acid sequences
– Ability to incorporate non-natural amino acids
– Cost-effective compared to full-length proteins

## Common Modifications and Conjugations
