Question

Arginine amino acid ph and equilibrium concentration

Answer 1

Answer:

If the pH is higher (in alkaline conditions) than the isoelectric point then the amino acid acts as an acid and donates a proton from its carboxyl group. This gives it a negative charge.

Answer 2

Answer:

The effect of pH on enzyme actvity

For example, pH can have an effect of the state of ionization of acidic or basic amino acids. Acidic amino acids have carboxyl functional groups in their side chains. Basic amino acids have amine functional groups in their side chains.
