Grains generally contain proteins and, depending
on the plant species, starch or triacylglycerols as
energy reserve sources. In the mobilization of these
three major nutrient reserves during germination,
they are hydrolyzed specifically by proteases,
amylases and lipases, respectively. Many researchers
have investigated seed lipase at the height of its
activity during grain germination (Hellyer et al.,
1999; Parques and Macedo, 2006).
