Physicochemical Analysis

Sequence-only estimates for a linear peptide with free termini, not experimentally measured molecular properties. Mass and formula exclude cyclization and disulfide formation. The optical estimates assume paired cysteines, 280 nm, 1 g/L and a 1 cm path. The N-end rule estimate is not a measured plasma half-life.
