Gelatin or gelatine (from Latin gelatus 'stiff, frozen') is a translucent, colorless, flavorless food ingredient, commonly derived from collagen taken from animal body parts. It is brittle when dry and rubbery when moist.
Gelatin comes from animal skin, bones, ligaments, and tendons because they are a huge source of the protein, collagen (yea, the stuff that keeps your skin nice). Turns out that collagen is a ...
To some, these facts may be pretty fascinating, but for most of us, that's just plain gross.
The packing structure of collagen has not been defined to the same degree outside of the fibrillar collagen types, although it has been long known to be hexagonal. [33] [81] [82] As with its monomeric structure, several conflicting models propose either that the packing arrangement of collagen molecules is 'sheet-like', or is microfibrillar.
Original - This is a schematic view of an typical animal cell. An animal cell is a form of eukaryotic cell that makes up many tissues in animals. Reason well labeled, encyclopedic, high quality SVG. i am renominating it sepratly because last time it was one of the concern.

A cell's ability to vitrify in the absence of metabolic activity, as in dormant periods, may be beneficial as a defense strategy. A solid glass cytoplasm would freeze subcellular structures in place, preventing damage, while allowing the transmission of tiny proteins and metabolites, helping to kickstart growth upon the cell's revival from ...
There are some structures I did not add because it was not clear to me how they should look. For all have doubts between cytoskeleton, microfibers and microtubules. If you would like to make another language version of it, message me and I can make an image without text for you or message me the names in the language you want them to appear.
The substrate in this case is gelatin, and the products are the polypeptides formed. Gelatinase binds to the substrate, gelatin, due to specificity of binding interactions on cell surface. The catalysis, associated with a zinc ion and amino acid residues, breaks the peptide bonds into polypeptides through cleavage.
