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.
Guano is a highly effective fertilizer due to the high content of nitrogen, phosphate, and potassium, all key nutrients essential for plant growth. Guano was also, to a lesser extent, sought for the production of gunpowder and other explosive materials.

The team then cooked fresh, shell-on hen eggs using four methods: hard-boiling, soft-boiling, sous vide and the new periodic cooking technique. In total, Di Maio and his colleagues prepared 160 ...
A Fischer–Tropsch synthesis can also be used to form guanine, along with adenine, uracil, and thymine. Heating an equimolar gas mixture of CO, H 2 , and NH 3 to 700 °C for 15 to 24 minutes, followed by quick cooling and then sustained reheating to 100 to 200 °C for 16 to 44 hours with an alumina catalyst, yielded guanine and uracil:
Off the heat, Pepin adds in the reserved raw, beaten eggs and a tablespoon of cream, continuing to stir vigorously, which lightly cooks the last bit of egg added (but less than the rest of the ...
Fukaya negi (深谷ネギ) – Often used to denote the types as thick as leeks used in Kantō region, but is not a proper name of a cultivar, and merely taken from the production area of Fukaya, Saitama. In the east, the white part of the onion near the base like to be used. Bannō negi ("multipurpose scallion") – young plants.
The monomeric avidin is created by treatment of immobilized native avidin with urea or guanidine HCl (6–8 M), giving it a lower dissociation K D ≈ 10 −7 M. [19] This allows elution from the avidin matrix to occur under milder, non-denaturing conditions, using low concentrations of biotin or low pH conditions. For a single high affinity ...
