  2. Guanidinium chloride - Wikipedia

    en.wikipedia.org/wiki/Guanidinium_chloride

    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 ...

  3. Guanidine - Wikipedia

    en.wikipedia.org/wiki/Guanidine

    Guanidine exists protonated, as guanidinium, in solution at physiological pH. Guanidinium chloride (also known as guanidine hydrochloride) has chaotropic properties and is used to denature proteins. Guanidinium chloride is known to denature proteins with a linear relationship between concentration and free energy of unfolding.

  5. Guanidinium thiocyanate - Wikipedia

    en.wikipedia.org/wiki/Guanidinium_thiocyanate

    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.

  6. Arginine - Wikipedia

    en.wikipedia.org/wiki/Arginine

    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.

  7. Polyhexamethylene guanidine - Wikipedia

    en.wikipedia.org/wiki/Polyhexamethylene_guanidine

    Polyhexamethylene guanidine (PHMG) is a guanidine derivative that is used as a biocidal disinfectant, often in the form of its salt polyhexamethylene guanidine phosphate (PHMG-P). Studies have shown that PHMG in solution has fungicidal as well as bactericidal activity against both Gram-positive and Gram-negative bacteria . [ 2 ]

  8. 7-Methyl-1,5,7-triazabicyclo (4.4.0)dec-5-ene - Wikipedia

    en.wikipedia.org/wiki/7-methyl-1,5,7...

    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]

  9. Guanine - Wikipedia

    en.wikipedia.org/wiki/Guanine

    Guanine (/ ˈ ɡ w ɑː n iː n / ⓘ) (symbol G or Gua) is one of the four main nucleotide bases found in the nucleic acids DNA and RNA, the others being adenine, cytosine, and thymine (uracil in RNA).
