Lipid Droplet Biogenesis & Lipophagy Simulator
Interactive 3D simulator of lipid droplet growth by Ostwald ripening, DGAT-driven triglyceride synthesis from the ER, and ATGL-mediated lipophagy gated by perilipin coating.
Lipid droplets are dynamic organelles that bud from the endoplasmic reticulum as neutral-lipid lenses at seipin-marked sites, then grow and shrink through a real physical coarsening process — Ostwald ripening — layered on top of active enzymatic turnover. This simulator renders a population of droplets in 3D whose radii evolve under a Lifshitz–Slyozov–Wagner ripening term, DGAT-driven triglyceride synthesis that favours larger droplets, and ATGL-mediated surface lipolysis that perilipin coating can suppress. Adjust synthesis, lipolysis, perilipin coverage and nucleation rate independently, fire a fasting pulse to watch hormone-sensitive lipolysis strip the perilipin coat and shrink the pool, and track live droplet count, total lipid volume, mean radius and net volume flux as the population reorganises.
Interactive 3D simulation of lipid droplets budding from the ER and coarsening by Ostwald ripening, with DGAT-driven triglyceride synthesis competing against perilipin-gated ATGL lipolysis.
