5α-Androstan-3β-ol, a steroidal androgen, demonstrates selective interaction with cellular components, showing affinity for the androgen receptor (AR) with an IC50 of 1.7 µM and activating the pregnane X receptor (PXR) in HepG2 cells with an EC50 of 0.8 µM. It selectively inhibits the hydroxylase activities of 16α- and 6β-hydroxylase over 16β- or 7α-hydroxylase, with IC50 values of 70 and 110 µM, compared to >150 µM for the latter enzymes, indicating a specificity in its enzyme inhibition profile. Additionally, administration of this compound at a dosage of 30 mg/kg results in a decrease in testis weight and sperm production in mice, highlighting its biological effects on male reproductive parameters.

Avenacein Y is a biochemical.

Cis-13-Octadecenoic acid, a monounsaturated fatty acid, is identified in bovine milk fat.

5-PAHSA, a FAHFA formed through the formal condensation of the carboxy group of palmitic acid with the hydroxy group of 5-hydroxystearic acid, serves as a human metabolite, possesses anti-inflammatory and hypoglycemic properties, and is categorized as a long-chain fatty acid. This compound, deriving from hexadecanoic acid and octadecanoic acid, is the conjugate acid of a 5-PAHSA(1-).

1-Stearoyl-2-palmitoyl-3-oleoyl-rac-glycerol is a triacylglycerol comprising stearic acid (at the sn-1 position), palmitic acid (at the sn-2 position), and oleic acid (at the sn-3 position), identified in bovine milk.

3,5-Dibromotyrosine 是一种有用的有机化合物，可用于生命科学领域的相关研究。其产品编号为 T65914，CAS号为 300-38-9。

Eicosapentaenoic acid (EPA) is metabolized into epoxyeicosatetraenoic acids (EpETE) by multiple cytochrome P450 isoforms. The predominant compound of this epoxygenase pathway, (±)17(18)-EpETE, induces relaxation in vascular and airway smooth muscles through its action on large conductance Ca2+-activated K+ (BKCa) channels, specifically by binding to the BKα channel subunits. Another notable epoxygenase pathway derivative, (±)11(12)-EpETE, also generated from EPA via CYP450 activity in both in vitro and in vivo studies, has biological and physiological roles that are yet to be fully elucidated.

1,3-Dipentadecanoyl glycerol, a diacylglycerol featuring pentadecanoic acid at the sn-1 and sn-3 positions, serves as an internal standard for quantifying ceramides and diacylglycerols in rat soleus muscle via LC-MS/MS.
