The Tg of zwitterion 10 after mixing with an equimolar amount of LiTFSI was -37 o C (see Figure 2). This was the lowest Tg among the mixtures of zwitterion
Equilibrium: Titration Curve of Amino Acid
If the zwitterion is treated with acid, that is, a solution containing H +, theH + will add to the COO-to form COOH. Similarly, treating the zwitterion with base will result in the loss of the removable proton attached to the NH 3 + group to form NH 2, The followingpH-dependent equilibrium can be drawn.

(CH2) 4CH3
As a zwitterion, serine has the structural formula '\ a) CH20H b) CH20H I NH2CHCOOH I NH2CHCOO-22. (2 pts.) Although the polysaccharides starch & cellulose arehth composed entirely of glucose units, cellulose is not digestible by humans because it contains glucose units linked by-glycosidic bonds.
