S: serine b) What are the three-etter abbreviations for the amino acids? L: E: glutamate S: ser L: E: glu c) What is the overall charge of the most abundant tripeptide species at neutral pH (pH 7.0)? 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)? S: polar, uncharged Select answernegalively hargedE L: Select answer E negatively charged continued below... e) What is the overall charge of the most abundant tripeptide species below pH 1.0?
