(1S)-Calcitriol (1α,25-Dihydroxy-3-epi-vitamin-D3), a natural metabolite of 1α,25-dihydroxyvitamin D3 (1α,25(OH)2D3), exerts potent actions through vitamin D receptor (VDR) activation, including the inhibition of keratinocyte growth and suppression of parathyroid hormone secretion [1].

(E)-Guggulsterone is an isomer of guggulsterone. As an FXR antagonist, it reduces blood lipids, induces heme oxygenase-1 expression, blocks DENV NS2B/3B activity, and inhibits DENV replication.

Prostaglandin D1 (PGD1) is the theoretical D-series metabolite of dihomo-γ-linolenic acid (DGLA), but to date it has not been isolated as a natural product. It is an inhibitor of ADP-induced platelet aggregation in humans with an IC50 value of 320 ng/ml, about 1/10 as potent as PGD2. 13,14-dihydro-15-keto Prostaglandin D1 (13,14-dihydro-15-keto PGD1) is the theoretical metabolite of PGD1 via the 15-hydroxy PG dehydrogenase metabolic pathway. No biological studies for this compound have been reported.

Steryl glucosides are neutral glycolipids commonly found in plant cell membranes and vegetable oils that contain a glucose moiety conjugated to a sterol lipid. They function as glucose donors in the biosynthesis of glucocerebrosides in plant microsomes and are metabolic precursors to acylated/esterified steryl glucosides. Steryl glucosides are the major component of filter- and engine-damaging precipitates formed during biodiesel production from transesterification of vegetable oils. This product contains a mixture of steryl glucosides.

12(S)-HETE is a product of arachidonic acid metabolism through the 12-lipoxygenase pathway. It is primarily found in platelets, leukocytes, and to a lesser extent in smooth muscle cells. It enhances tumor cell adhesion to endothelial cells, fibronectin, and the subendothelial matrix. tetranor-12(S)-HETE is the major β-oxidation product resulting from peroxisomal metabolism of 12(S)-HETE in numerous tissues, and Lewis lung carcinoma cells. No biological function has yet been determined for tetranor-12(S)-HETE. Some data indicate it may play a role in controlling the inflammatory response in injured corneas. In some diseases (e.g., Zellweger's Syndrome) peroxisomal abnormalities result in the inability of cells to metabolize 12(S)-HETE, which may be responsible for symptoms of the disease. The tetranor derivative of 12(S)-HETE is available as a research tool for the elucidation of the metabolic fate of its parent compound.

Galactosylcerebrosides are glycosphingolipids that contain a galactose attached to a ceramide acylated with a hydroxy or non-hydroxy fatty acid. They are metabolic precursors to sulfatides , found primarily in nerve tissues, and are the main glycosphingolipids in the central nervous system. Galactosylcerebrosides are involved in a multitude of cellular processes including cell agglutination, cellular signaling in glycosynapses, cellular development, and activation of T cells. They accumulate in globoid cells in the brain of patients with Krabbe disease, a disorder characterized by a deficiency in galactosylcerebrosidase activity. This product is a mixture of isolated bovine hydroxy galactosylcerebrosides.
