Between the tails of the phospholipids in a cell membrane, you typically find cholesterol molecules and various proteins. Cholesterol helps to maintain fluidity and stability of the membrane, while proteins can serve various functions, including transport, signaling, and structural support. This region is hydrophobic, contributing to the overall selective permeability of the membrane.
What else can I help you with?
Which molecule is found in the cells membrane and prevents the fatty acid tails from sticking together?
Cholesterol is the molecule found in cell membranes that prevents the fatty acid tails of phospholipids from sticking together. It intercalates between the phospholipids, maintaining membrane fluidity and stability across varying temperatures. This function is crucial for proper cellular function and the integrity of the membrane.
In a plasma membrane how do the tails of the phospholipid molecules lineup?
they are sandwiched between two layers of heads
What are lipids with polar heads and nonpolar tails called?
Lipids with polar heads and nonpolar tails are called phospholipids. They are a major component of cell membranes, with the polar heads facing the aqueous environment and the nonpolar tails forming the interior of the membrane.
What characteristics of phospholipid is important to their function?
they have a polar head and non-polar tails
Why are the outside heads of phospholipids located on the outside of the cell membrane?
Tails are Hydrophobic
What has heads and tails and are found in a cell membrane?
Phospholipids.

True or False.The cell membrane is formed by phospholipids with hydrophobic fatty acid tails facing outward to the cytoplasm and extracellular fluid and hydrophilic phosphate heads sandwiched between?
False. The cell membrane is actually formed by phospholipids with hydrophilic heads facing outward towards the extracellular fluid and cytoplasm, while the hydrophobic fatty acid tails are sandwiched in between.
Which aspect of phospholipids is most important to the formation of bilayers?
The dual nature of phospholipids, with hydrophilic heads and hydrophobic tails, is most important for the formation of bilayers. This allows them to self-assemble in water to form the lipid bilayer structure found in cell membranes.
Where are the water in-soluble hydrophobic tails of the phospholipids bilayer located?
The water-insoluble hydrophobic tails of phospholipids in the lipid bilayer are oriented towards the interior of the membrane, away from the surrounding water. This arrangement helps to shield the hydrophobic tails from the polar environment outside the cell membrane.
Do hydrophobic tails on phospholipids try to aviod water or be near water?
They avoid water. (The word "hydrophobic" literally means "water-fearing" :D )
