The conjugate acid is called the guanidinium cation, (C(NH 2) + 3). This planar, symmetric ion consists of three amino groups each bonded to the central carbon atom with a covalent bond of order 4/3. It is a highly stable +1 cation in aqueous solution due to the efficient resonance stabilization of the charge and efficient solvation by water ...
Guanidinium chloride is a weak acid with a pK a of 13.6. The reason that it is such a weak acid is the complete delocalization of the positive charge through three nitrogen atoms (plus a little bit of positive charge on carbon). However, some stronger bases can deprotonate it, such as sodium hydroxide: C(NH 2) + 3 + OH − ⇌ HNC(NH 2) 2 + H 2 O
4-Aminobenzoic acid (also known as para-aminobenzoic acid or PABA because the two functional groups are attached to the benzene ring across from one another in the para position) is an organic compound with the formula H 2 NC 6 H 4 CO 2 H. PABA is a white crystalline solid, [3] although commercial samples can appear gray.
Benzoic acid is cheap and readily available, so the laboratory synthesis of benzoic acid is mainly practiced for its pedagogical value. It is a common undergraduate preparation. Benzoic acid can be purified by recrystallization from water because of its high solubility in hot water and poor solubility in cold water. The avoidance of organic ...
Salmon, tuna, cod, anchovies and sardines are all rich in omega-3 fatty acids, especially docosahexaenoic acid or DHA, which is found in large quantities in the brain. ... (or 1.4 teaspoons) ...
If you’re struggling with dry skin this winter, we know it can feel like an uphill battle to keep your skin moisturized.Throw dermatitis into the mix, and the frustration compounds. No one wants ...
The supplement tricaprin, which is found in coconut or MCT oil, improved long-term survival for people with triglyceride deposit cardiomyovasculopathy, according to the results of a recent study.
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.
