What else can I help you with?
What causes the plasma membrane to resist freezing?
unsaturated fatty acid tails
Is bilayer hydrophilic?
A bilayer is composed of two layers of phospholipid molecules, which have hydrophilic (water-attracting) heads and hydrophobic (water-repelling) tails. The hydrophilic heads face outward towards the surrounding water, making the bilayer as a whole hydrophilic on the outer surfaces.
What has 3 tails and can be saturated or unsaturated?
A triglyceride molecule has 3 fatty acid tails attached to a glycerol backbone, and these fatty acid tails can be either saturated or unsaturated depending on the presence of double bonds in the hydrocarbon chain.
How are unsaturated fatty acids related to lipids?
Not all lipids are saturated. Unsaturated lipids come in liquid form and are not from animals. Saturated lipids are in solid form and do usually come from organisms other than plants such as animals.
How do hydrophobic and hydrophilic molecules form a bilayer?
Hydrophobic and hydrophilic molecules form a bilayer primarily through the self-organization of phospholipids in an aqueous environment. The hydrophilic "head" of the phospholipid molecules interacts with water, while the hydrophobic "tails" avoid water and face inward, away from the aqueous surroundings. This arrangement creates a bilayer structure, with the hydrophilic sides facing outward towards the water and the hydrophobic tails tucked inside, providing a stable barrier that separates the internal and external environments of cells.
How would the membrane shown in transparency behave if it's fatty acid tails consisted mostly of unsaturated fatty acids?
The lipids would flip and the heads become hydrophobic and the tails hydrophilic
The phospholipid molecules of most membranes have?
a hydrophilic head and hydrophobic tails. This structure allows the phospholipids to form a bilayer in water, with the hydrophobic tails facing inward and the hydrophilic heads facing outward, providing a barrier that controls the movement of molecules in and out of the cell.
What has a hydrophilic head which are stable in water and hydrophobic tails that keep water away?
Phospholipids have a hydrophilic head that is stable in water and hydrophobic tails that repel water. These molecules are key components of cell membranes, forming a bilayer structure with the hydrophobic tails facing inward and the hydrophilic heads facing outward towards the watery environment.
What is a double walled with molecules that have hydrophobic tails and hydrophilic head?
Phospholipid Bilayer
Are the lipids associated with the biological membrane hydrophobic or hydrophilic?
Hydrophyllic heads and hydrophobic tails.
What causes the plasma membrane to resist freezing?
unsaturated fatty acid tails

What has 3 tails and can be saturated or unsaturated?
A triglyceride molecule has 3 fatty acid tails attached to a glycerol backbone, and these fatty acid tails can be either saturated or unsaturated depending on the presence of double bonds in the hydrocarbon chain.
Do Phospholipids have hydrophilic and hydrophobic regions?
Yes, phospholipids have both hydrophilic (water-attracting) and hydrophobic (water-repelling) regions. The hydrophilic region is the phosphate group, which interacts with water, while the hydrophobic region is the fatty acid tails, which avoids contact with water. This dual nature allows phospholipids to form cell membranes and other structures.
Did cream kiss tails on his lips in sonic x?
yes
Why is a phospholipid both hydrophilic and hydrophobic?
They have both hydrophilic and hydrophobic heads. In a lipid bilayer, the hydrophilic head of the phospholipid faces the outside of the membrane while the hydrophobic head faces the the hydrophobic head of another phospholipid.
Is lipid tails hydrophilic or hydrophobic?
Lipid tails are hydrophobic, meaning they repel water. This is because they consist of long hydrocarbon chains that do not interact well with water molecules.
