Nettet11. okt. 2024 · It is critical that the anti-lipolytic effect of insulin is mediated sufficiently by low levels of PKB phosphorylated at either Ser 473 or Thr 308 or both sites. Moreover, anti-lipolysis in human adipocytes is very sensitive to insulin, half-maximal at 0.01 nM insulin (herein), while glucose uptake is half-maximal at 0.04 nM . NettetThe facilitative glucose transporter, GLUT4 undergoes insulin-dependent movement to the cell surface in adipocytes. The magnitude of the insulin effect is much greater for …
