Figure 2

Bar-plot of the Amino Acid frequencies. The bars are drawn on the position of λ _i = $m_i^{\left(M\right)}$/$m_i^{\left(N\right)}$, for each amino acid i. The red line indicates λ _DB computed using the Equation 2. Dotted blue line - λ _DHB 2,5-dihydroxybenzoic acid; dashed line - λ _alphacyano alpha-Cyano-4-hydroxycinnamic acid; dot dashed line - λ _sinapica . 3,5-Dimethoxy-4-hydroxycinnamic acid.
