Identify the Amino Acids Below as Positively (+) Charged, Negatively

Identify the amino acids below as positively (+) charged, negatively (-) charged, able to form disulfide bonds (SS), and/or having OH groups that can be phosphorylated (P) by protein kinases at pH 7.0. Place the appropriate symbols (+, -, SS, or P) in the blanks beside the three-letter codes. (Hint: Some amino acids have none of these properties.)
