BESSER promotes three important molecules of the plant: the coenzyme A (CoASH) and the two amino acids methionine (Met) and cysteine (Cys). CoASH is the source of adenosine triphosphate (ATP), which is the main energy-transfer molecule of the metabolism and it is used in all biomolecule synthesis, at growing and development states of the plant. Met and Cys are key amino acids in protein formation which are related to cell lignification, thus increasing vegetal tissue. As a consequence, the plant is able to enhance resistance to external stresses. In addition, certain species of sulphur from BESSER boost Oxygen Active Species (AOS) with no impact on vegetal tissue.
