Document Summary
We have a great deal of collagen 25% of proteins is collagen in animals. It is extracellular (outside cell) and forms strong sheets. Form web-like structures take on slightly different forms depending where they are in the body. Huge family 1 14, and they all slightly vary in amino acids. The main source of commercial gelatin (denatured collagen is): Fibroblast cells make collagen collagen fibers look like strong robes cut one open (cross section) and looking at the end of it you would see a bunch of dots. Collagen molecule is a triple helix they do not line up perfectly, they stager themselves. When they stack up together- get gaps where there is a lack of signal where there are stacks in the same place there"s a dark line. Collagen fibers are stripped and this is why. Fibrils root together to form a collagen fiber. A bunch of triple helices small piece of a collagen fibril.
