Are enzymes hydrophilic?
Enzymes, being proteins, are made of many amino acids of which some are hydrophobic. These hydrophobic amino acids tend to shun water and fold into the interior of the protein enzyme. Enzymes are in solution so the hydrophobic sections would be away from the solution on the inside and the hydrophillic amino acids would tend to be on the outside of the enzyme. So, is a limited sense, you could say enzymes are hydrophyllic
Why spingomyelin can't form micelle structure but palmitic acid can?
Well, not having these structures before me, I still can say that one of these types has both a hydrophyllic end and a hydrophobic end so that it naturally forms a micelle.
How do Integral membrane proteins function?
The location of their polar and non-polar amino acids. I'll buy that. But there's more. the membranes are hydrophyllic (polar) on the outside and hydrophobic (non-polar) on the inside. Proteins that pass through the membrane are stabilized by the membrane, and also stabilize the membrane in return. Based on the sequence of the amino acids, there are polar / hydrophyllic parts of the protein and nonpolar / hydrophobic parts. They interact with the membrane like little magnets to hold everything in place...
Is potassium fat-soluble?
No; when they say Oils and Water do not mix they mean to say that Hydrophobic liquids are immiscible [won't mix with] Hydrophyllic liquids. In a similar way, the two types of solids that make solutes are different; one ionic and polar, the other both non-ionic and non-polar. Hydrophobic means 'water-disliking' because they are non-polar which in this case means they have no net-electric charges; they are non-ionic. Hydrophyllic means 'water-liking' because they have a net-electric charge; they are ionic - just like the ionic, non-polar-fat disliking Potassium Ion!
Are integral proteins amphipathic?
yes it can as its outside edges stick out of the phospholipid bilayer exposing it to the watery environment (polar/hydrophilic) and part of the protein is inside the bilayer along with the phospholipid tails (hydrophobic/nonpolar).
Is disaccharides hydrophobic?
no it is a hydrophyllic
Are the lipids associated with the biological membrane hydrophobic or hydrophilic?
Hydrophyllic heads and hydrophobic tails.
Is glucose an amphipathic?
I don't think that glucose has both hydrophyllic and hydrophobic ends though it is soluble. Think phospholipid for an amphipathic molecule.
The sustance that reduces surface tensin in the alveoli is?
Surfactant is a substance which lines the inside of alveoli. It is composed of a phospholipid bilayer, which have hydrophyllic and hydrophobic properties. This allows it to reduce surface tension.

Why do some materials diffused through the mimbrean while others don't?
the membrane may only allow small particles or may only allow polar/nonpolar molecules, hydrophobic vs hydrophyllic molecules
