What is the charge of lysine in a neutral pH environment?
In a neutral pH environment, the charge of lysine is positive.
What is the optimal pH for the stability and function of lysine in biological systems?
The optimal pH for the stability and function of lysine in biological systems is around pH 7. Lysine is most stable and functions best at this neutral pH level.
What is the charge on the lysine molecule when it is in a solution with a pH of 7?
The charge on the lysine molecule is positive when it is in a solution with a pH of 7.
What is the isoelectric point of lysine and how does it affect its chemical properties?
The isoelectric point of lysine is around pH 9.74. At this pH, lysine carries no net charge and is least soluble in water. This affects its chemical properties by influencing its solubility, reactivity, and ability to interact with other molecules.
What is the isoelectric point of lysine and how does it affect its properties in biological systems?
The isoelectric point of lysine is around pH 9.74. At this pH, lysine carries no net charge. In biological systems, the isoelectric point of lysine affects its solubility and interactions with other molecules. Below its isoelectric point, lysine carries a positive charge, while above it, lysine carries a negative charge. This influences its ability to bind to other molecules and participate in various biological processes.

What is the net charge for lysine?
Depends on the pH. The lysine nitrogen is positively charged until pH 9.0 (so at physiological pH it is positively charged). See http://usm.maine.edu/~newton/Chy251_253/Lectures/AminoAcids/AminoAcids2.html near the bottom.

What is the effect of lysine at pH 7 on protein structure and function?
At pH 7, lysine can affect protein structure by interacting with other amino acids through electrostatic interactions. This can lead to changes in the protein's overall shape and stability. Additionally, lysine can participate in post-translational modifications, such as acetylation, which can impact protein function by altering its activity or localization within the cell.
Is lysine an acid or a base?
Lysine is a basic amino acid, It contains the classic -COOH group and an amino group steming off of the chiral center for the molecule. It has a basic side chain with a terminal amino group. In aqueous solutions (i.e. the cell) it acts as a base.
Where does lysine bond another lysine?
i just came across a lysine-lysine bond in a b-barrel n-termini fragment that's embedded in the membrane
Is rice rich in lysine?
Yes, it is rich in lysine.
What is the net charge of the dipeptide glu-lys at physiological pH?
The net charge of a dipeptide, such as glu-lys (glutamate-lysine) at physiological pH, which is around 7.4, would depend on the pKa values of the constituent amino acids. Glutamate has a side chain pKa of around 4.3 and lysine has a side chain pKa of around 10.8. At pH 7.4, glutamate's side chain is mostly deprotonated with a −1 charge, while lysine's side chain is mostly protonated with a +1 charge, resulting in a net charge of 0 for the dipeptide glu-lys.
Is lysine an enzyme?
No. Lysine is an amino acid. Amino acids are the building blocks of proteins.
