Gelatin is a heterogeneous mixture of water-soluble proteins of high average molecular masses, present in collagen. Proteins are extracted by boiling the relevant skin, tendons, ligaments, bones, etc. in water. Type A gelatin is derived from acid-cured tissue. Type B is derived from lime-cured tissue.
Caution
Dry gelatin, when stored in airtight containers at room temperature, will remain unchanged for many years. When heated at 100°C in the presence of air, it swells becomes soft and disintegrates to a carbonaceous mass with evolution of pyridine bases and ammonia.

Secretion of effector molecules is one of the major mechanisms by which the intracellular human pathogen Legionella pneumophila interacts with host cells during infection. Specific secretion machineries which are responsible for the subfraction of secreted proteins (soluble supernatant proteins [SSPs])
Gelatins were prepared from chicken and turkey heads in a series of batch extractions at 2 different temperatures (50 and 60°C), and their composition and functional properties were evaluated. Gelatin yield from chicken and turkey heads was 52.29 and 62.76%
In the engineering of soft tissues, designing the scaffolds with adequate strength and controllable biodegradation properties are essential. To fulfill such design criteria gelatin/carbohydrate chitosan (G/CC) scaffolds have gained much attention in engineering replacement of soft tissues. In this research
A mixture of novel glycopeptides from glycosylation between cold water fish skin gelatin hydrolysates and glucosamine (GlcN) via transglutaminase (TGase), as well as glycation between fish gelatin hydrolysate and GlcN were identified by their pattern of molecular distribution using MALDI-TOF-MS.
