You may want to obtain a field guide to the area in order to know which birds to attract.
Phospholipids. Phospholipids make up an important class of lipids for the construction of cell membranes. The phospholipids are not true fats because they have one of the fatty acids replaced by a phosphate group.This sketch of a phospholipid molecule shows two fatty acids and a phosphate group attached to a glycerol backbone.hospholipids.

CH 7 Membranes Cellular Membranes Phospholipids are the most abundant lipid in the plasma membrane. Phospholipids are amphipathic molecules, containing hydrophobic and hydrophilic regions.The fluid mosaic model states that a membrane is a fluid structure with a âmosaicâ of various proteins embedded in it.Made of Proteins & Lipids Fluidity of Membranes Phospholipids in the plasma membrane can move within the bilayer.Most of the lipids, and some proteins, drift laterally.he fluid mosaic model states that a membrane is a fluid structure with a âmosaicâ of various proteins embedded in it.
