Peptide bond, plz help?
When are two amino acids linked by a peptide bond?
Is it when two ribosomes attach simultaneously??
cleavage of the trityl group
hi,
how can I cleave the trityl group from cysteine containing peptides. I used TFA/TES/DCM but did not work well. is necessary to use EDT?
thanks...
why is a peptide bond stronger than an ester bond?
what structural feature of the peptide bond gives it additional bond strength?
Are there any natural sources of orexin peptides?
Or foods that help to increase the production of orexin (no, I'm not mis-spelling it haha). I read that orexin is key to wakefulness, and I have a...
The peptide bond joining amino acids into proteins is a specific example of...
...the ________ bond. A) glycosidic? A) glycosidic
B) carbonyl
C) hydrogen
D) ester
E) amide

Recently there has been an explosion of peptide utilization in all science fields, thus the growing demand for the synthesis of synthetic peptides. Peptide have been proved to act as great probes for the study of protein-protein interactions, the binding of ligands to the extracellular domains of cell surface proteins and receptors, studying epitopes in immunology or antibody-antigen interactions, the study of inhibitory peptides on protein functions such as inhibition of cancer-inducing proteins, and enzyme-protein substrate interactions to mention a few. Also the design and application of fluorescent substrate-based peptides can be used to determine the selectivity and activity of peptidases.
Synthetic peptides can be utilized as probes in all the previously mentioned scenarios as they all involve amino acid residue interactions . Although many of these protein interactions often involve amino acid residues from distant protein domains, there are many examples where short stretches of amino acids are vital for protein-protein interactions (acting as contiguous epitopes) and thus allow the application and the use of synthetic peptides for the study of a broad range of biological phenomena.
The creation of antibodies specific for a protein is quickly done using peptides. Peptides will not fold similarly to native proteins (due to their smaller size and lack of many native residues), however they can be useful in the generation of antibodies.
