Stability of $\alpha$-Helix structure of proteins depends upon:

An electric current is passed through an aqueous solution of a mixture of alanine (isoelectric point $6.0$), glutamic acid $(3.2)$, and arginine $(10.7)$ buffered at $pH$ $6.0$. What is the fate of the three amino acids?

At which $pOH$ values is the isoelectric point of an amphoteric amino acid typically found?

Amino acids are produced on hydrolysis of:

The cell membranes are mainly composed of

The isoelectric point of alanine is $pH = 6$. At which $pH$ will the maximum concentration of the zwitterion of alanine be present?
