31.Hydrophobic interactions of the tails of phospholipids can produce?
lipid bilayer ------ Actually, this is not necessarily true. What 'clusters' form is going to depend on not only the concentration of the lipids in solution, but what the composition of the solution is as well. Generally, lipids in a water-solution (or a salt solution, or buffer, or whatever it may be) will first form micelles, ie. lipid monolayers where the tails all face inwards, to prevent their hydrophobic tails from being exposed to the aqueous environment. Depending on the conditions of the solution, they may form liposomes (ie. micelles that have a double layer rather than a monolayer), or sheets of phospholipid bilayers. The ends of the latter option, however, are energetically unfavorable. If your lipids are in an oil solution, then you are going to see the formation of inverse-micelles, where the tails face out towards the lipophilic (hydrophobic) environment, and the hydrophilic head groups are going to face inwards. ------
Why is lipids good for you?
Because cells are bathed in an aqueous solution, and something hydrophobic provides a good barrier to allow cells to selectively decide what gets in and what goes out. Lipids are suitably hydrophobic for this purpose
When membranes are frozen and then fractured they tend to break along the middle of the bi layer because?
the hydrophobic interactions that hold the membrane together are weakest at this point.
Why do amphipathic molecules form micelles in water?
Amphipathic molecules are by definition those that contain both hydrophobic (water hating) and hydrophilic (water loving) regions. The area of the molecule that likes water tends to stay in the aqueous region whereas the region of the molecules that hates water tends to cluster with other hydrophobic regions. This untimately results in the hydrophobic regions packing together and forming a region that is impervious to water molecules. Such a structure is called a micelle
Explain what distinguishes lipids from other major classes of macromolecules?
Lipids are not soluble in water. improved..>> macromolecules have smaller subunits eg. protein-amino acid, carboyhdrate monosacharide, nucleic acid-nucleotide. unlike all the above examples lipids subunits are fatty acids which do not form covalent bonds with one another, rather they 'aggregrate' together.
What does it mean to congregate?
Congregate means to come together as a group.
What is another word for sit together?
congregate
What is an antonym for congregate?
sorry this one isn't great but it's disperse because congregate means bring together
Another word for come together?
congregate, convene
What is a congregate meal?
Many people eating together
The word meaning sit together is?
"congregate."
Why are phospholipids arranged as they are in a bi-layer?
Membranes self assemble as a result of the hydrophobic effect. This is the tendency of nonpolar substances to aggregate in aqueous solution and exclude water molecules. This can be shown by the hydrophobic tails coming together, and the hydrophilic heads facing the outside and inside of the cell.
What is a hydrophobic bond?
There is no such thing as a hydrophobic bond, It is a hydrophobic force. These forces come about when two areas of 2 different molecules containing hydrophobic sections come close together. like in protein's the hydrophilic sections come together to form bonds and the hydrophobic sections come together and so are seen as bonds but in reality they are not bonding but are just brought together to keep the hydrophobic parts away from aqueous environment (see lipid bi layers as an example)
Why is palmitic acid insoluble?
It is highly organic in nature. The long "fatty" tail of Carbon/Hydrogen is hydrophobic (doesn't like water). It will clump together in an aqueous solution like an oil rather than dissolve.
What does congerate?
I do not believe that "congerate" means anything. You may be thinking of congregate (meaning gather together, as in a congregation).
