true or false. at physiological PH, nearly all amino acids
have overall positive charge
True False 1) At physiological pH, nearly all amino acids have an overall positive charge. 2) The dipeptide abbreviated as Gly-Lys is the same as the dipeptide abbreviated as Lys-Gly. tide 3) The peptide sequence Gly-Gly-Gly gives the primary structure of a tripeptide. 4) The u-helix is a secondary structure. 5) The triple helix of collagen is a tertiary structure.
