Mapdb Number Enter your answer as a whole number. d) At physiological pH, what is the best description of the chemical properties of the side chain (R group)? T: polar, uncharged P: hydrophabic R: positively charged continued below... e) What is the overall charge of the most abundant tripeptide species below pH 1.0? Number Enter your answer as a whole number. f) What is the overall charge of the most abundant tripeptide species at pH 11.5 Number Enter your answer as a whole number. g) What type of intermolecular force could the side chains form with water? (Note that these are interactions are with water, not with other amino acids.) O hydrophobic interactions O hydrogen bonds ionic interactions

Explanation / Answer

The amino acids are the online, proline and arginine.

C) At physiological pH, arginine is positively charged (+1) and the other two amino acids carry no charge. So, the net charge on the peptide is +1.

D) At physiological pH, the charges on amino acid are,

E) At pH 1.0, the overall charge on peptide TPR is 1. (T=0, P=0, R=+1).

F) At pH 11.5, the overall charge on peptide TPR is -3 (T=-1, P=-1, R=-1).

G) The dude chains of amino acids firm hydrophobic interactions with water.
