● There is one feature common to all those compounds found in the `color{brown}("acid soluble pool.")`
● They have molecular weights ranging from `color{brown}("18")` to around `color{brown}("800 daltons (Da) ")` approximately.
● The `color{brown}("acid insoluble fraction,")` has only four types of `color{violet}("organic compounds ")`i.e., proteins, nucleic acids, polysaccharides and lipids.
● These classes of compounds with the exception of `color{violet}("lipids")`, have `color{violet}("molecular weights")` in the range of ten `color{violet}("thousand daltons")` and above.
● For this very reason, `color{violet}("biomolecules,")` i.e., chemical compounds found in `color{violet}("living organisms")` are of two types.
● One, those which have molecular weights less than `color{violet}("one thousand dalton")` and are usually referred to as `color{violet}("micromolecules")` or `color{violet}("simply biomolecules")` while those which are found in the acid insoluble fraction are called macromolecules or`color{brown}(" biomacromolecules.")`
● The molecules in the `color{violet}("insoluble fraction")` with the exception of lipids are`color{brown}(" polymeric substances.")`
● There is a reason that `color{violet}("lipids,")` whose molecular weights do not exceed `color{brown}("800 Da,")` come under acid insoluble fraction, i.e., `color{brown}("macromolecular fraction.")`
● `color{violet}("Lipids")` are indeed small molecular weight compounds and are present not only as such but also arranged into structures like `color{violet}("cell membrane")` and `color{violet}("other membranes.")`
● When we `color{violet}("grind a tissue,")` we are disrupting the `color{violet}("cell structure.")`
● `color{violet}("Cell membrane")` and other membranes are broken into pieces, and form vesicles which are not water soluble.
● Therefore, these membrane fragments in the form of vesicles get separated along with the `color{violet}("acid insoluble pool")` and hence in the `color{violet}("macromolecular fraction.")`
● Lipids are not strictly `color{violet}("macromolecules.")`
● The `color{brown}("acid soluble pool")` represents roughly the `color{violet}("cytoplasmic composition.")`
● The `color{violet}("macromolecules")` from `color{violet}("cytoplasm and organelles")` become the `color{violet}("acid insoluble fraction.")`
● Together they represent the entire chemical composition of `color{violet}("living tissues")` or `color{violet}("organisms.")`
● In summary if we represent the chemical composition of `color{violet}("living tissue")` from abundance point of view and arrange them class-wise, we observe that `color{brown}("water")` is the most abundant chemical in `color{violet}("living organisms.")`
