18-Hydroxy-11-deoxy Corticosterone (18-OH-DOC) is a mineralocorticoid produced by the zona fasciculata of the adrenal gland, with its biosynthesis regulated by adrenocorticotropic hormone (ACTH) and angiotensin II. This regulation heightens 18-OH-DOC production in isolated human adrenal glomerulosa cells and allows for its formation from 11-deoxy corticosterone (DOC) in human SK-MEL188 melanoma cells. As an intermediate in progesterone metabolism, 18-OH-DOC can be converted to aldosterone in rat adrenal glands' capsular portion. Its continuous infusion (200 μg/rat per day) has been shown to raise systolic blood pressure in uninephrectomized saline-drinking rats, and elevated plasma levels of 18-OH-DOC have been observed in the adb/db mouse model of type 2 diabetes.
1-Docosahexaenoyl-sn-glycero-3-phosphocholine, an ester product, is a phospholipid containing DHA (docosahexaenoic acid), often used in biomedical research as an important source of omega-3 fatty acids.
Ethyl cis-4,7,10,13,16,19-Docosahexaenoate, the ethyl ester of Docosahexaenoate (DHA), is selectively enriched in the ethyl ester fraction through the alcoholysis process involving fatty acid ethyl esters from tuna oil and lauryl alcohol.
4,7,10,13,16-Docosapentaenoic acid (22:5n-6) is an endogenous metabolite [HMDB0002349], [CHEBI:32698], [CHEMBL113282], [PubChem CID: 3082141], that belongs to (non-methylene-interrupted polyunsaturated fatty acids) (NMIFA). This molecule is (biosynthesized from adrenate) and is classified as a (non-methylene interrupted fatty acid), (medium-chain fatty acid), and (DPA).
