Explain the fluid-mosaic model of membranes. how are proteins found at membranes described? what types of side chains would be found in regions of proteins that interact with phospholipid tails?

He fluid mosaic model of the plasma membrane. The fluid mosaic model of the plasma membrane describes the plasma membrane as a fluid combination of phospholipids, cholesterol, and proteins. Carbohydrates attached to lipids (glycolipids) and to proteins (glycoproteins) extend from the outward-facing surface of the membrane.

I’d say a : water molecules

The arrangements of lipids in the membrane makes the cell semi permeable .
