Proteins and Polypeptides: basics, structures, properties
Temperature increases disrupt the existing hydrogen bonds as well as other non-polar hydrophobic interactions. As the temperature increases, so does the kinetic energy. This causes the molecular components of the protein to vibrate, which leads to the broken bonds. This, in turn, creates a pattern of ruptures or breaks of any nearby …
How do chemical bonds store energy? | Socratic
Chemical bonds do not store energy. Explanation: Chemical bonds certainly "contain" potential energy, and the atoms want to move to a lower potential energy (become more stable). When methane, CH4, forms, the valence electrons end up in more stable (lower energy) C-H bonds. These bonds are fairly strong, so methane is …

Important Biomolecules
Fats (lipids) Fats are the primary long-term energy storage molecules of the body. Fats are very compact and light weight, so they are an efficient way to store excess energy. A fat is made up of a glycerol, which is attached to 1 to 3 fatty acid chains. Most of the energy from fats comes from the many carbon bonds in these long, fatty acid chains.
