A molecule with a polar head and two non polar tails?
Lipids, man!Could be the phospholipid bilayer of a cell membrane to be more specific.phospholipidSoap and detergent molecules have a polar head and nonpolar tail to help dissolve an dwash off dirt and oil.
When lipids and water are mixed do the water molecules isolate themselves into droplets?
This is possible only if the ratio of lipid is massive to the ratio of water. However, this is usually not the case. In most cases, when lipids and water are mixed, the hydrophobic properties of the lipids cause the lipids to coalesce at the top of the water without mixing, because that lipids are less dense than water.
What accounts for the grease spots in lipids?
Some lipids do have grease spots and some lipids do not have grease spots. The lipids that get them typically contain sphingosine or glycerol.
Do lipids have monomers or polymers?
Lipids are not polymers but are macromolecules. So we cannot speak of monomers and polymers of lipids.Lipids are triglycerides, the simplest form being formed by a condensation reaction between a molecule of glycerol (which has 3 -OH groups) and 3 fatty acids.
What are the four classes of biological molecules?
The four principle types of biological molecules are carbohydrates, lipids, proteins, and nuclei acids. These molecules are some of the most important things in a humans body. Without these biological molecules the human body could not function.
Cell membranes are composed primarily of what type of molecule?
A phospholipid bilayer
Predominant lipids in the lipid bilayer?
Lecithin , Phospholipid .
What type of lipids form a living cell membrane?
lipid bilayer
What kind of lipids make up the bilayer that form the membrane?
Phospholipids
Do lipids control the activity of genes?
Lipids do not have a role in controlling the functions of genes. In a cell, the most notable function of lipids is in the lipid bilayer/cell membrane.
What kinds of lipids make up the bilayer forms cell membranes?
phospholipids
What kind of lipids make up the bilayer that forms cell membranes?
Phospholipids
What kind of lipids make up the bilayer that form cell membranes?
Phospholipids
What does a lipid tail do?
Well the lipids bilayer tails repel eachother because
What make up the bilayer of the cell membrane?
It's called the phospholipid bilayer. It's made of phospholipids and some other varients of lipids.
While water continually orients phospholipids into a lipid bilayer it does not fix the lipids permanently into position Thus the bilayer is considered to be what in nature?
Fluid nature
What part of the cell membrane make up the bilayer?
It's called the phospholipid bilayer. It's made of phospholipids and some other varients of lipids.
