Gelatin contains many glycines (almost 1 in 3 residues, arranged every third residue), proline and 4-hydroxyproline residues. A typical structure is -Ala-Gly-Pro-Arg-Gly-Glu-4Hyp-Gly-Pro-.

What is gelatin ?
Gelatin is composed of proteins and peptides that are derived from collagen. Collagen is the main structural protein of the various connective tissues in animals
How jell-o works:
Gelatin is normally extracted from various animal by-products such as bones. It is usually obtained from boiling the bones of cattle, pigs, cows, and horses. Most recently the food industry has begun to utilize gelatin extracted from fish bones to prevent religious stigmas that might damage product popularity.
when you boil the water and add the jell-o packet you break the weak bonds that hold the collagen protein chains together. Each chain will float around in the bowl until the gelatin cools and new bonds form between the amino acids in the protein. The water mixed with the flavors and colors then becomes trapped between the newly formed bonds. Jell-o is mostly water, but the liquid is trapped in the chains so Jell-o jiggles when you shake it. If you heat the Jell-o, you will break the bonds that hold the protein chains together, liquefying the gelatin again.
- it is so often used because it is a solid binder agent (it glues different products together), awesome stabilizer, great texture, and it is reactive to heat (it can change state with small temperature changes)
- it is used in many food products such as: marshhallows, gummies, jell-o, yogurts, etc
- it is also used in many other products such as: glues, cosmetics, medical instruments, etc.
- Gelatin is also used by synchronized swimmers to hold their hair in place during their routines
