What You Need to Know
Hydrogen bonds form between gelatin polypeptides (Gly-Pro-Hyp repeats) and water molecules, causing triple helix structures to partially unwind and absorb 5-10x their weight in water.
Prevents clumping in hot liquids, ensures smooth texture in gels like panna cotta or marshmallows.
