Which of the following amino acids has its isoelectric point at the highest pH?
A) glutamic acid
B) lysine
C) serine
D) histisdine
E) cysteine
Isoelectric Point
The pH at which a molecule carries no net electrical charge, crucial for predicting molecule behavior in different environments.
Amino Acids
Organic compounds that serve as the building blocks of proteins, each containing an amino group (-NH2), a carboxyl group (-COOH), and a distinctive side chain.
