They're given that the pKa of COOH is $2.4$ and the pKa of the amine group is 9.6. The solution they were given says the pH is just $\frac{2.4+9.6}{2} = 6.1$, but I don't see any reason why this should be true especially since this answer initially appears independent of the given concentration of ...
Glycine is an amino acid that has a single hydrogen atom as its side chain. It is the simplest stable amino acid (carbamic acid is unstable), with the chemical formula NH2‐CH2‐COOH. Glycine is one of the proteinogenic amino acids. It is encoded by all the codons starting with GG (GGU, GGC, GGA, GGG). Glycine is … See more Glycine was discovered in 1820 by French chemist Henri Braconnot when he hydrolyzed gelatin by boiling it with sulfuric acid. He originally called it "sugar of gelatin", but French chemist Jean-Baptiste Boussingault showed … See more Its acid–base properties are most important. In aqueous solution, glycine is amphoteric: below pH = 2.4, it converts to the ammonium … See more The principal function of glycine is it acts as a precursor to proteins. Most proteins incorporate only small quantities of glycine, a notable … See more The presence of glycine outside the earth was confirmed in 2009, based on the analysis of samples that had been taken in 2004 by the NASA spacecraft Stardust from comet See more Although glycine can be isolated from hydrolyzed protein, this route is not used for industrial production, as it can be manufactured more conveniently by chemical synthesis. The two main processes are amination of chloroacetic acid See more Biosynthesis Glycine is not essential to the human diet, as it is biosynthesized in the body from the amino acid See more In the US, glycine is typically sold in two grades: United States Pharmacopeia (“USP”), and technical grade.
