Unfractionated heparin as a pharmaceutical is heparin that has not been fractionated to sequester the fraction of molecules with low molecular weight. In contrast, low-molecular-weight heparin has undergone fractionation for the purpose of making its pharmacodynamics more predictable.nfractionated heparin as a pharmaceutical is heparin that has not been fractionated to sequester the fraction of molecules with low molecular weight.

Best Answer: Yogurt is sour because it contains lactic acid which also gives it its distinctive taste. Yogurt is only sweet if sugar or artificial sweeteners are added.
Bear in mind, too, that the longer you keep yogurt, the stronger its taste will become. If mold appears on yogurt, or if it develops an off odor, flavor or appearance, you should always discard it immediately.
