Lipid Metabolism Compartmental Diagram

Compartment-specific lipid pools with labeled flux arrows and simplified molecular icons.

When to use this prompt

For lipid biology, metabolic engineering and nutritional-biochemistry figures.

The prompt

A lipid metabolism compartmental diagram drawn as four labeled compartments connected by flux arrows.

Compartments (boxes), each with a distinct color:
- Intestinal lumen (slate) — dietary triglyceride pool
- Plasma (navy) — chylomicrons / VLDL / LDL / HDL particles drawn as differently sized circles
- Liver (coral) — hepatic triglyceride and cholesterol pool, with VLDL secretion arrow out
- Adipose tissue (gold) — triglyceride storage pool, with FFA release arrow back to plasma

Flux arrows between compartments labeled with key enzymes / transporters:
- LPL (lipoprotein lipase) on plasma -> adipose VLDL hydrolysis arrow.
- HSL (hormone-sensitive lipase) on adipose -> plasma FFA release arrow.
- CETP (cholesteryl ester transfer protein) on plasma HDL -> VLDL exchange.
- LDLR (LDL receptor) on plasma LDL -> liver uptake arrow.

Add small simplified lipid molecule icons (TG, CE, PL, FFA) as legend at the bottom-right.

Style: biomedical illustration, polished textbook quality, restrained palette with one accent color per compartment, white background, clean labels. Suitable for biochemistry textbooks and metabolic-disease review figures.

Variations

With drug-target overlay

Mark drug-target sites with small star icons and labels: statins (HMG-CoA reductase in liver), PCSK9 inhibitors (plasma -> liver LDLR axis), and fibrates (PPAR-alpha in liver).

Tips

Color compartments distinctly. Lipid biology readers track compartments visually first.
Label every flux with the responsible enzyme or transporter. Unlabeled arrows are not informative.
Use a legend for lipid molecule abbreviations (TG, CE, PL, FFA). They are domain-specific.
