Serine participates in the biosynthesis of important biomolecules for cellular proliferation, such as amino acids (cysteine and tryptophan), nitrogenous bases, phospholipids, sphingolipids and molecules with activity against abiotic stress (glycine-betaine). In addition, it plays an indispensable role in many cellular processes, such as the metabolism of a carbon unit (C1), or cellular signaling mechanisms (such as phosphatidylserine), being one of the three amino acids (serine, tyrosine and threonine) that can be phosphorylated by kinases.
