Oleoyl‐Estrone [PDF]

open access: yesMedicinal Research Reviews, 2011
AbstractOleoyl‐estrone (OE) is a powerful slimming agent that is also present in plasma and adipose tissue, where it is synthesized. It acts through the formation of a derivative W. OE effects (and W levels) are proportional to the dose. OE reduces food intake but maintains energy expenditure (thermogenesis).
