It is involved in enzymatic processes and oxidation-reduction reactions, it is a constituent of the amino acids cystine, cysteine ​​and methionine, which constitute about 90% of the total S of the plant.

Ferredoxins, proteins participating in photosynthesis, biological fixation of atmospheric nitrogen (N) and other electron transfer reactions, contain S in large quantities.  

Deficiency – Younger leaflets with generalized chlorosis. The symptoms can appear in the peripheral region of the leaflets, sometimes as isolated spots, of different sizes and contours, sometimes together, forming extensive yellow areas. The chlorotic leaflets are transparent, highlighting the veins, already somewhat clear, on the yellowish background.
