Ph of aspartate
WebbThe neutral form of aspartic acid is dominant between pH 1.88 and 3.65, thus the isoelectric point is halfway between these two values, i.e. 1/2 (pKa1 + pKa3), so isoelectric point will be 2.77. Aspartic Acid … WebbThe incubation was performed at 36.7 °C wherein such conditions were applied to simulate the temperature of human body. The study involved the pH measurements of liquids with incubated samples made using the pH-meter Elmetron CX-701 (Zabrze, Poland). Analysis was performed for chitosan/poly(aspartic acid)-based hydrogels.

Under physiological condition (pH = 7.4), the amino group (NH 2 group) is protonated and becomes NH 3+ but carboxylic acid group (COOH group) is deprotonated and present as COO –. Aspartic acid is acidic in nature (pka = 3.9) due to presence of acidic side chain (CH2COOH).
