It is not understood why the uninterrupted bonding-chain cannot be, because the stability as to maximum length was estimated for objects of which one can definely say that they do not correspond to living matter. On the other hand : If it is established already since decennia as an indisputed fact that there are no sharp boundaries between mechanical partitions, colloidal, and molecular solutions, while one may obtain the colloidal state as a result of mechanical dispersion of the very coarse as well as by aggregation from the opposite side [the coarse phase being dispersed and the fine phase aggregating], - then one also may get used to the idea that there do exist large molecules which one may cut through with a knife or tear up with one's hands . . . Energetic and mechanical objections against this do not exist. [We may continue to follow increasing molecular or particle size : true solution, i.e. homogeneous mixture (and therefore very small particles) (such as that of table salt in water) ==> "macro-bio-molecules in some medium" (such as hemoglobine molecules in red blood-particles in blood) ==> colloidal solution or (heterogeneous) mixture (such as a suspension or emulsion, involving larger, light-scattering, clots) ==>==> one single giga-molecule suspended in an aquous serum-like medium (such as an organism).]
