Phospholipids

from class:

Microbiology

Definition

Phospholipids are amphipathic molecules that form the core structure of cell membranes, consisting of a hydrophilic head and two hydrophobic tails. They play a critical role in cellular functions and metabolic processes.

congrats on reading the definition of phospholipids. now let's actually learn it.

ok, let's learn stuff

5 Must Know Facts For Your Next Test

  1. Phospholipids are essential components of the lipid bilayer in microbial cell membranes.
  2. They can be broken down by phospholipases during catabolism to release fatty acids and other products.
  3. The catabolism of phospholipids contributes to the energy production in microbes through beta-oxidation pathways.
  4. Phospholipid degradation can lead to the formation of signaling molecules involved in microbial metabolism.
  5. Enzymes such as lipases and phospholipases are crucial for the breakdown of phospholipids during microbial lipid metabolism.
