Ph of aspartate
WebbThe ionic form of this amino acid is known as aspartate. 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). WebbSolution pH was not adjusted to the same at different temperatures. Deamidation rate at 40°C was faster in acidic buffers than in basic buffers. However, this trend is reversed at …

WebbHypoxia-inducible factor-1α (HIF1α) can suppress tumor cell proliferation. Here, we discovered that HIF1α acts as a direct repressor of aspartate biosynthesis involving the suppression of several key aspartate-producing proteins, including cytosolic glutamic-oxaloacetic transaminase-1 (GOT1) and mitochondrial GOT2. Accordingly, HIF1α…. WebbIn one procedure, aspartic acid polymerizes at 180 °C concomitant with dehydration and the formation of a poly(succinimide).
