Phospholipids are made up of a hydrophilic head and a hydrophobic tail. The head group has a 'special' region that changes between various phospholipids. This head group will differ between cell membranes [types of cells] or different concentrations of specific 'head groups'. The fatty acid tails call also differ, but there is always one saturated and one unsaturated 'leg' of the tail.
What else can I help you with?
How do polar molecules differ from non-polar molecules?
Polar molecules have positive charge on one side and negative charge on other side. Non polar molecules have covalent bond and do not have positive and negative charge on one or other side of the molecule.
What is stickier a non polar molecule or a polar one?
A polar molecule.
What is different between polar and non-polar molecules?
A polar molecule is one that has a negatively charged end and a positively charged end, which form poles. A non-polar molecule doesn't.
The head of a phospholipid can be described as?
The head of a phospholipid is hydrophilic, meaning it is attracted to water and tends to be located on the exterior surface when in a lipid bilayer. It usually contains a polar group such as a phosphate, which gives it its water-loving properties.
Is the cholesterol molecule mostly non polar or polar and why?
It is MOSTLY non polar because it has 27 carbons arranged in several ring structures, and a side chain. This makes it non polar. The only polar parts of the molecule is an -OH group on one of the ring structures.
The water soluble portion of a phospholipid is the polar head which generally consists of a glycerol molecule linked to a phosphate group?
No, you do not have that quite correct. A Phospholipid molecule has one end that is hydrophilic (is attracted to water) while the other end is hydrophobic (is repelled water but is attracted to fats).
How do polar molecules differ from non-polar molecules?
Polar molecules have positive charge on one side and negative charge on other side. Non polar molecules have covalent bond and do not have positive and negative charge on one or other side of the molecule.
What is polar and not polar?
A polar molecule, like water, is one that has a slight positive charge on one side and a slight negative charge on the other. A non-polar molecule, like a lipid, is one that has a neutral charge throughout.
What is stickier a non polar molecule or a polar one?
A polar molecule.
Which part of the phospholipids is attracted to water?
The hydrophilic end of the phospholipid is the end that is attracted to water. Only the hydrophilic end will come in contact with the water. The other, hydrophobic ends, will face inward and touch each other.
What is the difference between covalent bond that is polar and one that is not?
the polar one is less stable than the non-polar one
Is hydrogen non-polar or polar?
Hydrogen is considered non-polar because it only has one electron and it shares it with other elements to form covalent bonds. This means there are no significant differences in electronegativity to create a polar bond.
Is the phospholipid molecule has two parts the polar end and the bipolar end?
No, you do not have that quite correct. A Phospholipid molecule has one end that is hydrophilic (is attracted to water) while the other end is hydrophobic (is repelled water but is attracted to fats).
The head of a phospholipid water and is said to be?
The head of a phospholipid is a phosphate group and is hydrophilic, which means it is attracted to water, in particular the intracellular and extracellular fluids.
What is different between polar and non-polar molecules?
A polar molecule is one that has a negatively charged end and a positively charged end, which form poles. A non-polar molecule doesn't.
Polar molecules behave as though they?
possess a separation of electric charge, with one end being slightly positive and the other slightly negative. This results in interactions with other polar molecules, such as hydrogen bonding, which can influence their physical properties such as solubility and boiling point.
What is polar and nonpolar?
polar is thick and non-polar is ligt and will float to the top of whatever you put it in
