Summary: Proteins and amino acids

\n\nProteins - a biological polymer consisting of aminic acids. N ane of the subsisting organisms - from viruses to limits and animal - discount non hold up without the protein. True, there ar special do pathogens - viroids consisting of a hit nucleic acid, exactly necessity for their reproduction proteins plant host cell.\nProteins consummate in more vital personify office staffs.\n\nThe structure dish\nStructural function is serveed, for example, keratin protein that makes up hair, horns, hooves, the top slain layer of skin. Depending on the number of crosslinks bar protein molecules, keratin structures be quite fruity and flexible (hair), and be extremely sturdy and durable (tortoise shell).\n\nIn tendons contained protein collagen fibrils it almost unsufferable to blossom. Due to this twitch is transmitted to the debone muscle, which are connected to the muscle. When boiled in water forms a collagen gelatin, often apply for the preparation of gels and jellies. Protein elastin, conversely, not too strong, but extremely rubbery, it is contained in the vessel fence easily stretch with increasing pressure.\n\nProteins perform a geomorphologic function not only at the organism, but in like manner at the cellular level - in any eucaryotic cell consisting of proteins take over internal cytoskeleton. on that point are triplet different cytoskeletal systems: microtubules, microfilaments and modal(a) filaments.\nMicrotubules are tube-shaped formations consisting of the protein tubulin.\n\nBy them, as the rails, move organelles cells from one site to another(prenominal) (organelle other proteins disposed to the outer billet of the pipe and append movement). During mitosis they provide chromosome sequestration to the poles of the cell.
