Definition
Galactolipids – a lipid composed of glycerol, two fatty acids attached to the sn-1 and sn-2 position of this glycerol, and at least one galactose head group attached to the sn-3 position via an ether bond.
Glycerophospholipid – a lipid composed of glycerol, two fatty acids attached to the sn-1 and sn-2 position of this glycerol, and a head group attached to the sn-3 position via a phosphate.
Sterol – subgroup of steroids with a hydroxyl group at the 3-position of the A-ring.
Sphingolipid – lipid containing a long-chain base linked via an amide group to a fatty acid and optionally with a head group attached to the terminal hydroxyl group of the long-chain base.
On the Arabidopsis Root Lipidome
Overall Root Function
Roots are a defining feature of vascular plants as the organs that anchor plants to the soil. They are also responsible for nutrient and water absorption. In recent years, more and more evidence accumulated that...
