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.

Arginine is the amino acid with the formula (H 2 N)(HN)CN(H)(CH 2) 3 CH(NH 2)CO 2 H. The molecule features a guanidino group appended to a standard amino acid framework. At physiological pH, the carboxylic acid is deprotonated (−CO 2 −) and both the amino and guanidino groups are protonated, resulting in a cation.
Guanidine is a special case of a species that is exceptionally stable when protonated, analogously to the reason that makes perchloric acid and sulfuric acid very strong acids. Acids with a p K a of more than about 13 are considered very weak, and their conjugate bases are strong bases.
A co-chair of the House of Representatives’ Congressional DOGE Caucus said there is "real motivation" behind accomplishing its mission of cutting the federal deficit. Rep. Blake Moore, R-Utah ...
Guanidinium thiocyanate can be used to deactivate a virus, such as the influenza virus that caused the 1918 "Spanish flu", so that it can be studied safely.. Guanidinium thiocyanate is also used to lyse cells and virus particles in RNA and DNA extractions, where its function, in addition to its lysing action, is to prevent activity of RNase enzymes and DNase enzymes by denaturing them.
