1. i) (15 points) Sketch the titration curve of the following hypothetical amino acid, if you titrate it with 0.1M HCl. Assume your amino acid is at physiological pH at the beginning of the titration. Label everything on your titration curve clearly for full credit. pKa ( a NH3") = 9.2, pka ( a COOH) = 2.5, pka (RCOOH) = 4.5

13. Sketch a titration curve for the titration of a monoprotic weak acid HA with a strong base. The titration reaction (neutralization) is: HA + OH + H2O+ A On the curve, clearly label the points that correspond to: i. the equivalence point ii. the region with maximum buffering iii. pH = pka iv. pH depends only on [HA] v. pH depends only on [A-] vi. pH depends only on amount of strong base added.

i have no clue what amino acid this unknown is . maybe serine
?? pleade help! i also need to locate the eq points it can be from
1-3 points but atleasy 2 , the pka2 location , and the expermental
molecular weight value. if you can label it on one of the graphs (
they are the same) the chocies are below ( it most likely will not
be glycine ) .

Please show work!
Valine is an essential amino acid, which means that it cannot be manufactured in the body and must be obtained through dietary sources It is a branched-chain amino acid that works with the other two BCAAs (isoleucine & leucine) to promote normal growth, repair tissues, regulate Wood sugar, and provide the body with energy Correct the drawings below (i e, add or remove lone pairs, charges, and atoms) to show valine at pH 1. pH 7. and...
