The plasma proteins, finding themselves, of course, outside the unimol-bonding-continuum, have, as a result of their multiple bonding ability (see also the carbohydratic proteins [proteins associated with sugars and the like] ), important vehicle functions, as in the transport of vitamines, hormones, medicines "slag", etc. Except for fibrinogen [fibrous protein], that is the only linear protein occurring in plasm, the chief carriers of biological activities (among which also the AAR-bodies [I presume that the latter bodies belong to the immune system] ), are globulines, occurring in a large number of variants [Globulines are proteins that are folded up into more or less spherical structures. They all are structurally ordered to carry out special functions].
