Adipocyte metabolism

“Adipocyte metabolism” does not refer to a single molecule, protein, receptor, enzyme, transporter, or gene product. Instead, it encompasses the collective biochemical processes occurring within fat cells—primarily white and brown adipocytes—including energy storage as triglycerides during times of nutrient excess and mobilization through lipolysis when energy is needed by peripheral tissues. These processes are tightly regulated by hormonal signals such as insulin (which promotes lipid storage) and catecholamines like norepinephrine/adrenaline acting on β-adrenoceptors (which stimulate lipolysis). In addition to their role in energy balance, adipocytes secrete numerous bioactive molecules known as adipokines—including leptin and adiponectin—that regulate appetite control, inflammation status, insulin sensitivity throughout the body,[1][2]and overall metabolic health.[4] Dysfunctional regulation leads to diseases like obesity-related insulin resistance.[5] Because “adipocyte metabolism” describes an entire set of cellular functions rather than an individual druggable entity or therapeutic target classically defined in pharmacology/biomedicine,[7] it should not be considered a canonical molecular target.

Not applicable to "adipocyte metabolism" itself. Mechanisms depend on the specific molecular targets within this process: - Stimulation/inhibition of lipolysis via hormone-sensitive pathways - Modulation of insulin sensitivity through PPARγ activation or mTORC2 signaling - Regulation of thermogenesis via UCP1 in brown adipocytes
