At high concentrations of guanidinium chloride (e.g., 6 M), proteins lose their ordered structure, and they tend to become randomly coiled, i.e. they do not contain any residual structure. However, at concentrations in the millimolar range in vivo, guanidinium chloride has been shown to "cure" prion positive yeast cells (i.e. cells exhibiting a ...
The general structure of a guanidine. Guanidines are a group of organic compounds sharing a common functional group with the general structure (R 1 R 2 N)(R 3 R 4 N)C=N−R 5. The central bond within this group is that of an imine, and the group is related structurally to amidines and ureas.

It involves the reaction of an unprotected peptide thioester with a second, unprotected peptide that has an N-terminal cysteine residue. It is carried out in aqueous solution at neutral pH, usually in 6 M guanidine.hydrochloride, in the presence of an arylthiol catalyst and typically gives near-quantitative yields of the desired ligation product.

7-Methyl-1,5,7-triazabicyclo[4.4.0]dec-5-ene (mTBD) is a bicyclic strong guanidine base (pK a = 25.43 in CH 3 CN and pK a = 17.9 in THF). [3] mTBD, like 1,5,7-triazabicyclo[4.4.0]dec-5-ene and other guanidine super bases, can be used as a catalyst in a variety of chemical reactions. [4]
