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.
Vanilla, lemon, key lime, peach and strawberry are just a few of the many kinds of flavored yogurts available. Most flavored yogurt products contain some type of sugar or non-nutritive sweetener in addition to natural or artificial flavors and colors.hile plain low-fat yogurt only contains naturally occurring sugars, roughly half the sugar in the vanilla-flavored variety comes from added sugars. This means that added sugars account for about 30 percent of the calories in low-fat vanilla-flavored yogurt.
