Considering the 3[alpha]/[beta]-[[sup.18]F]FCA epimers
, it was found that 3[alpha]-[[sup.18]F]FCA shows a slight, yet significant decrease in time-to-peak of the liver TAC and excretion to gallbladder and intestines proceeded faster.
One of those confounders is the C-3 epimer
of (3-epi) 25(OH)[D.sub.3], which was previously thought to exist in infants only and, as such, wasn't of much concern, but is now known to be present at variable, albeit low, levels in virtually all human serum (J.

Because of the position of chiral carbons, which makes the product technically a C-4 epimer
of D-fructose, only about 20 percent of the sugar is metabolized.
Abstract.--Idarubicin (structural analogue of daunomycin) and epirubicin (epimer
of adriamycin) are two "second-generation" anthracyclines that are widely used in chemotherapy against leukemias and metastatic breast tumors, respectively.
Alginate is a beta- 1,4-linked polymer of mannuronic acid and its C5 epimer
, guluronic acid.

Currently, [gamma]-sitosterol, an epimer
of [beta]-sitosterol, has been insisted to possess antihyperglycemic activity by increasing insulin secretion in response to glucose confirmed with immune histochemical study of pancreas [14,15].
Alginate, the biopolymer of b-D- mannuronic acid its C-5 epimer
a-L-guluronic acid, has wide range of industrial and pharmaceutical applications (Butt et al., 2011).
Failure to measure this epimer
may possibly inflate overall 25OHD measurements.
