Table 4 DSC results for nanoparticles composed of stearic (SLN S) or arachidic acid (SLN A) with or without lysine (Lys), as well as controls of stearic and arachidic acid and their physical mixtures with Lys. Values of ΔH (J/g), Onset (°C), Melting Point (°C) and recrystallization index (RI (%)) shown.

From: Production of rumen- and gastrointestinal-resistant nanoparticles to deliver lysine to dairy cows
