Titration of Amino Acids The pKavalues of thecarboxyl groupand the ammonium group of an amino acid, as well as the pHi, can be determined by titrating the conjugate acid withbase.Figure 14.2shows a typical titration curve for glycine. As base is added, some of the conjugate acid is convert...

On the day following the day of transfection, the culture medium was replaced with medium containing DMEM (high glucose, Glutamax, Thermo Fisher Scientific), 2% FBS, 1% MEM non-essential amino acids solution (Thermo Fisher Scientific) and 1% PS. On the third day following transfection, the ...
Proteins are built up from units called amino acids. The simplest amino acid is glycine, the structure of which can be written in two ways: One has NH3+ and COO- in the molecule and other NH2 and COOH.a) consult the table of pKa values and decide which is the better representation of...
