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 else can I help you with?
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 are macromolecules with high hydrogen and carbon content and few oxygens. They are hydrophobic, meaning they have little to no affinity for water. Lipids play important roles in energy storage, cell membrane structure, and signaling in the body.
Do the lipids you refer to as oils have high water content?
No, lipids such as oils do not have high water content. Oils are hydrophobic substances, which means they do not mix well with water and therefore have very low water content.
How may lipids and proteins be used as carbon and energy source?
Lipids and proteins can be broken down by metabolic processes to release energy in the form of ATP. Lipids are a rich source of energy due to their high carbon content, which fuels cellular processes. Proteins can also be broken down into amino acids that can be used for energy production in the absence of carbohydrates or fats.
How many grams of energy does lipids have?
Lipids provide approximately 9 calories of energy per gram. To convert calories to grams in terms of energy, it’s important to note that grams measure mass, while calories measure energy. Therefore, when discussing the energy content of lipids, it's accurate to say they contain 9 calories per gram, which is the highest energy yield among macronutrients.
Are peanuts proteins or lipids?
they are proteins because they can be eatable by humans Lipids are found in bacteria etc.. so peanet is ony have protein
What are the physical properties of lipids of?
They are insoluble in water, have high energy content, content little amount of inter-molecular water.

No, lipids such as oils do not have high water content. Oils are hydrophobic substances, which means they do not mix well with water and therefore have very low water content.
Are there carbon-hydrogen bonds in lipids?
Yes, lipids contain carbon-hydrogen bonds. These bonds are a key component of the structure of lipids, such as fatty acids, triglycerides, and phospholipids. Carbon-hydrogen bonds contribute to the high energy content of lipids.
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.
Rich sources of stored energy that are dissolvable in organic solvents?
Waxes, polymers, and some lipids are examples of organic compounds that store energy and can be dissolved in organic solvents. These substances have high energy content and can be used as fuel sources or raw materials for various industrial processes.

Lipids are a rich source of energy due to their high carbon content, which fuels cellular processes. Proteins can also be broken down into amino acids that can be used for energy production in the absence of carbohydrates or fats.
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.
What kinds of foods are in high in lipids?
butter and lard
What kinds of food are high 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.
What kind of energy source do lipids provide?
Lipids primarily provide long-term energy storage in the form of fats. When broken down through metabolism, lipids release a high amount of energy, making them an efficient source of fuel for the body.
How many grams of energy does lipids have?
Lipids provide approximately 9 calories of energy per gram. To convert calories to grams in terms of energy, it’s important to note that grams measure mass, while calories measure energy.
