For instance, our group has shown that the treatment of diabetic mice with D-chiro-inositol, an
epimer of myo-inositol, can restore nerve conduction velocity and preserve nerve structural integrity (24) and that D-chiroinositol, methyl-D-chiro-inositol, and dibutyryl-D-chiro-inositol can prevent and ameliorate somatic and autonomic nerve function in rats and rabbits (37).
Petasis, Resolvin D1 and its aspirin-triggered 17R
epimer. Stereochemical assignments, antiinflammatory properties, and enzymatic inactivation.
Galactose is a C-4
epimer of glucose and is catalyzed to glucose-1-phosphate by galactokinase, the rate-limiting step of metabolism for galactose exclusively in the liver [5, 6].
This represents a drastic decrease in estrogenicity from the 17[beta]-AED
epimer. The presence of the hydroxyl group at C7 of 17[beta]-AET resulted in 1/587th the ability to activate the ER[beta].
The program recently began quantitating DEQAS materials with real values assigned by NIST, and is also working on standardizing measurements for 25(OH)D2 and D3, the C-3
epimer of 25(OH)D2 and D3, and 24,25(OH)2D, he said.
Among the estrogen-imprinted MIPs, 17[beta]-estradiol (E2) has been templated to develop MIPs as synthetic estrogen receptors (8-11).17[alpha]-Estradiol (a natural
epimer of E2) (12) and 6-ketoecradiol (a pseudo E2) (13) were also reported for MIPs preparation to target E2.

Epimer), Istanbul, Turkiye
[4-8] The alginate chemical structure is composed of a polymer arranged in homopolymeric block structure of urinic acid [beta]-D-mannuronate and its C-5
epimer [alpha]-L-guluronate.
Cooccurrence of 9-isocyanopupukeanane and its C-9
epimer in the nudibranch Phyllidia bourguini.
However, the alkaloids ergosine, ergonine, ergine, and their
epimers were detected in low amounts, while ergovaline and its
epimer ergovalinine were the major components (about 80% of total) of the ergopeptine fraction, in agreement with Siegel and Bush (1997).
It is the
epimer of arbutin, which even in very low concentration can inhibit the activity of tyrosinase.
