factor (PAF) is a
potent mediator
that occurs at very
low concentrations
in cells and tissues

15. Biological Processes Regulated by
Eicosanoids

16. •Lipid rafts are plasma membrane
microdomains rich in cholesterol and
sphingolipids.
•important for neuronal cell
adhesion, axon guidance and synaptic
transmission.
•crucial for neural development and
function.

17. Structural support

18. Function as antibacterial

20. While plant oils such as cotton, coconut,
palm, castor beans, soy, and
sunflowers are also natural sources of
stearic acid,
Soap making. deodorants foundation
creams, hand lotions, hair straightening
products, and shaving creams.

22. Biodiesel is a clean-burning fuel produced
from plant lipids such as soybean oil and will
be a good source of feul in near future.
Lubricants
palm, sunflower, soybean oils are used to
make industrial bio-lubricants. engine
oil, grease and metalworking fluids.
