Are fats soluble in petroleum ether?
yes because they are hydrophobic
Are lipids hydrophobic or hydrophobic?
All Lipids are hydrophobic: that's the one property they have in common. This group of molecules includes fats and oils, waxes, phospholipids, steroids and cholesterol.
Are triglycerides hydrophobic?
Yes they are. This is because they are a lipid. Lipids consist of oils, waxes and fats which are not soluble in water hence the term hydrophobic (water fearing)
Which part of a soap is responsible for its ability to dissolve fats and oily dirt?
hydrophobic end
Why doesn't fat absorb water?
Fats are hydrophobic, meaning they are "scared of water." they will not mix with water, they will always stay separate.
Which statement most accurately explains why cholesterol and phospholipids are amphipathic but fats are not?
Cholesterol and phospholipids contain both hydrophilic and hydrophobic regions; fats are primarily hydrophobic. Save

Which part of a soap is responsible for its ability to dissolve fats and oily dirt?
hydrophobic end
On a phospholipid which part is hydrophobic?
The substance that forms the hydrophobic tail on the back end of a phospholipid are fatty acids. Phospholipids are not "true fats" as they have a phosphate group that replaces one of the fatty acids
What is in a substance that makes it hydrophobic?
Substances are hydrophobic because they are nonpolar. Nonpolar molecules are made up of elements with little difference in their electronegativities so they do not have charges or partial charges. Water is a polar molecule so it tends to be attracted to other molecules that are polar as well. This is often summed up as "like attracts like". Some examples of hydrophobic molecules include fats and oils which are nonpolar because they have large hydrophobic hydrocarbon chains.
What is lipids or fats?
Lipids are broadly defined as molecules that are hydrophobic (insoluble in water) or ampiphilic (possessing both hydrophobic and hydrophilic properties). Phospholipids are a subgroup of ampiphilic lipids which contain a negatively charged phosphate group.
Name the subunit that makes up fats?
Triglyceride makes up fats.
What molecule has hydrophobic fats oils waxes and steroids made from mainly carbon and hydrogen atoms in long chains?
lipids
Why doesn't fat absorb water?
Fats are hydrophobic, meaning they are "scared of water." they will not mix with water, they will always stay separate.
Are fats hydrophillic?
No. Hydrophillic freely associates with water, readily entering into solution, and water loving. Fats, or lipids, are hydrophobic, which are incapable of freely associating water molecules, insoluble, and water-fearing.
