Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent handle lipids by class, structure, biological role, nutrition and clinical measurement, routing medical questions to professionals.

A broad class of organic compounds that are insoluble in water but soluble in non-polar solvents, including fats and oils, phospholipids, sterols, waxes and signalling lipids; they form membranes, store energy and act as signals.

What it is for: Cell membranes, energy storage, signalling and nutrition.

It can be classify by structure; measure blood lipids with clinicians; follow dietary guidance on fats; study in biochemistry.

Distinguishing features

Hydrophobic or amphipathic

Diverse classes

Membrane building blocks

Blood levels relate to cardiovascular risk

What it looks like

Oils, fats and waxes; in cells, membranes and droplets.

How it is recognised

Classes such as triglycerides or phospholipids

Names ending in -lipid or -sterol
