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.
Old-fashioned Greek yogurt is made with goatâs milk while American yogurt, and many of the American-made âGreek-styleâ products, are made from cowâs milk. (âGreek-styleâ yogurts may also contain thickening agents like condensed milk or gelatin.) All yogurt starts out the same, with milk and live cultures. In the case of Greek yogurt, the live cultures are the active bacteria S. thermophilus (St) and L. bulgaricus (Lb), which ferment the milk to make its characteristic tangy taste. With Greek yogurt, the milk and culture combo is then strained with a filter to remove the liquid whey part of milk.
