no, proteins are not.
the answer would be lipids (otherwise known as fats and oils)
Adipose tissue is specialized for energy storage and thermal insulation in the body. It consists of adipocytes, which store triglycerides as a long-term energy reserve, and also provide thermal insulation to help regulate body temperature.
Cells use lipid molecules for energy storage as well as insulation and structuring. These molecules are mostly known in the vernacular as fats although they do encompass more than just traditional fat molecules.
As long as you do NOT compress the insulation. If your wanting the area for storage your R-value (insulating value) will only be as good as the depth of the rafter you are covering.
The organic macromolecule used for the long term energy storage in animals is triglyceride.
Lipids are mainly used by the body for long-term energy storage. They are stored in adipose tissue and can be broken down to provide a source of energy when needed. In addition to energy, lipids also play a role in insulation, cell structure, and hormone production.
Fat is the long term energy storage medium for most animals. Glycogen is the short term storage medium. Glycerol is the backbone of triglycerides.
Lipids.
Lipids, specifically triglycerides, are considered to be a long-term storage form of energy in organisms. Lipids are highly efficient molecules for storing energy due to their high energy density and low solubility in water.
Energy in living beings is stored as chemical energy. For long-term energy storage a sugar is used; for short-term energy storage, ATP.
Fat is an energy-rich organic compound composed of carbon, hydrogen, and oxygen. It provides a concentrated source of energy as it contains twice as many calories per gram as carbohydrates or protein. Fats are stored in the body for long-term energy storage and insulation.
yes it does
Fat.
