Figure 4 Regarding GSTL genes, AtGSTL2 and AtGSTL3 show similar expression patterns, particularly in green tissues, such as leaves, flower sepals, siliques, and developing seeds, whereas AtGSTL1 transcripts are almost exclusively found in roots, senescing leaves, and pollen (Figure 4)
Alpha-tocopherol derivatives, such as acetate in alpha-tocopherol acetate, are cleaved prior to absorption in the small intestine by esterases, meaning that alpha-tocopherol is absorbed, not the alpha-tocopherol derivative
