The high energy density (i.e. the relatively large amount of
energy released per unit of mass) of fat stores is due to three main factors.
1) The completely reduced carbons of fatty acids have a higher energy content than the
partially oxidized carbons of carbohydrates and proteins.
2) The fortuitous fact that the reduced carbons have covalent bonds to light atoms (hydrogen rather than to the heavier oxygen) means that the fully reduced hydrocarbon compounds are
lighter than the partially oxidized carbohydrates.
3) Lipids are hydrophobic molecules and therefore fat stores contain little water, which would add to the weight of the molecules without adding to the energy content.
Hope that helps.

What is a macromolecule that has a high content of hydrogens and carbons and few oxygens These molecules have little or no affinity for water?
lipids
Which type of macromolecule contains high energy bonds and is used for long term energy storage?
lipids
What do lipids do for the human body?
provide insulation, protection, and stored energy
Do fruits have lipids?
Strawberries are not considered to be lipids. There is no fatty content that is found in strawberries and they are known to lower the serum cholesterol.
What are the physical properties of lipids of?
They are insoluble in water, have high energy content, content little amount of inter-molecular water.
Do the lipids you refer to as oils have high water content?
NO
What is the meaning of lipid content?
Lipids are triglycerides, fatty acids, and oils that are stored energy in cell membranes. Lipid content is the percent or amount of lipids found in a substance.
What kind of food are lipids?
Foods that are high in lipids Foods that are high in lipids are those with high content of fats, oils, and cholesterol, which add calories and cause weight issues such as nuts, castor bean, and many others.

Why is consuming too many lipids bad for you?
An unhealthy diet can cause high cholesterol. Foods with high lipid content usually have a lot of cholesterol.
Why are lipids important for bears?
Lipids are fat, oils, and waxes. When bears go into hibernation, bears need lipids because they take longer to break down and keep the bears body working during the winter. Lipids are the high energy source giving the bear the energy while they're sleeping.
