Fatty Acid Structure Molecule Models

SKU: 62114

$85.95USD Each


Fatty acids are carboxylic aliphatic chains with a methyl group at one end and a carboxylic acid group at the other. They have a general formula of H(CH2)nCOOH. Aside from chain length, they differ in the number of cis & trans double bonds in the hydrocarbon chain.

This molecular model kit can build a triglyceride (triacylglycerol) structure such as trioleintristearin or tripalmitin. Or, build up to three 19 carbon atom models of important saturated, mono-unsaturated and poly-unsaturated fatty acids found in corn oil, canola oil & fish oils. This includes alpha linolenic acid (omega-3), linoleic acid (omega-6) & oleic acid (omega-9), common dietary fats.

Most fatty acids are single aliphatic chains but our free 3D Molecular Model Builder build branched ones such as prostaglandin as well. Or, use to build less common one fatty acid chemical structures such as docosahexaenoic acid, an omega 3 fatty acid found in breast milk that is important to human infant brain development.

Note: If you need just a single model, our 3D Molecular Model Builder will list just the parts for that structure. It can also tell you what our various student organic chemistry model sets can build & whether they need extra parts.


Steroids & Hormones

Some fatty acids are precursors to hormone-like substances that facilitate blood clotting, lipid levels & pressure regulation as well as our immune & inflammation responses. This molecular model kit has enough parts to build steroid structures such as cholesterol & cortisol. In addition, it can also build important hormones such as testosterone, estrone, estradiol, progesterone & testosterone.


Phospholipids differ slightly from triglycerides in having 2 rather than 3 fatty acid chains attached to the glycerol backbone. They are important building blocks in cell membranes. This model kit has most of the necessary parts but the extras & quantities needed are shown in brackets & listed in Related Products below. The important phospholipids are: phosphatidylserine (1 each 60103E, 60300E, 60407E), phosphatidylcholine (2 x 60103E, 1 each 60401E, 60407E), phosphatidylethanolamine (1 each 60103E, 60200E, 60401E, 60407E).
