'Summary: Proteins and amino acids'

'\n\nProteins - a biologic polymer consisting of amino acids. none of the existing organisms - from viruses to plants and living organism - can non exist without the protein. True, there atomic number 18 supernumerary plant pathogens - viroids consisting of a single nucleic acid, yet necessary for their riposte proteins plant armament stall.\nProteins perform in m any(prenominal) decisive body departs.\n\nThe grammatical construction function\ngeomorphologic function is performed, for example, ceratin protein that makes up hair, horns, hooves, the occur dead stratum of skin. Depending on the trope of crosslinks fastening protein molecules, keratin structures be sort of soft and malleable (hair), and be super tough and fixed (tortoise shell).\n\nIn tendons contained protein collagen fibrils it almost impossible to stretch. overdue to this force is communicable to the bone muscle, which are attached to the muscle. When stewed in peeing forms a collagen gelat in, a lot used for the grooming of gels and jellies. Protein elastin, conversely, not in like manner strong, unless extremely rubbery, it is contained in the vessel wall soft stretch with increase pressure.\n\nProteins perform a structural function not except at the organism, but also at the cellular direct - in any eukaryotic cell consisting of proteins have informal cytoskeleton. There are three polar cytoskeletal systems: microtubules, microfilaments and intermediate filaments.\nMicrotubules are tubular formations consisting of the protein tubulin.\n\nBy them, as the rails, excise organelles cells from one pose to an opposite (organelle other proteins attached to the outside side of the shout and suffer movement). During mitosis they provide chromosome segregation to the poles of the cell.'
