When drawing the structure of an amino acid, which of the following statements is true? The amino group is positively-charged at physiological pH (7.4). The alpha carbon is the second carbon within the R group of the amino acid. The carboxy group is positively-charged at physiological pH (7.4). 3 of these 4 responses are correct. The amino group is drawn to the right side of the alpha carbon.
