triglyceride
Let an agent explain triglycerides and their structure, relay biological roles, blood levels and dietary sources from biochemistry and clinical sources, describe industrial uses, and distinguish triglycerides from cholesterol, phospholipids, free fatty acids and other lipids, without giving personal medical advice.
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 explain triglycerides and their structure, relay biological roles, blood levels and dietary sources from biochemistry and clinical sources, describe industrial uses, and distinguish triglycerides from cholesterol, phospholipids, free fatty acids and other lipids, without giving personal medical advice.
An ester formed from glycerol and three fatty acids, the main constituent of body fat in animals and of vegetable oils and animal fats, serving as the principal form of energy storage and transport in blood, with specific triglycerides named by their fatty acids such as tripalmitolein, trilinolenin, tricaprin, trilaurin and mixed-acid glycerides such as 1-oleoyl-2,3-dilinoleoyl-sn-glycerol; blood triglyceride levels are a clinical marker of cardiovascular and metabolic risk, and triglycerides are the raw material of biodiesel and soap.
What it is for: Energy storage and lipid raw material.
It can be explain structure and naming; relay biology and clinical role; describe uses; distinguish from other lipids.
Distinguishing features
Three ester bonds
Energy storage
Clinical marker
Named by fatty acids
What it looks like
Oils and fats; not visible as molecules.
Physical character
normal fasting blood level: under 150 mg/dL - about 1.7 mmol/L, guideline threshold
energy density: about 9 kcal/g
common fatty acids: palmitic, oleic, linoleic, stearic list
How it is recognised
Glycerol esterified with three fatty acids
Simple triglycerides such as trilaurin and tricaprin; mixed triglycerides with defined positions
Cholesterol is a sterol; phospholipids have a phosphate head; free fatty acids are unesterified

- How should biochemistry and clinical sources be linked?
- The registry entry has merged aliases naming specific molecules; should they be split off?
