MeSH Heading: Trans Fatty Acids
Tree Number(s): D10.251.355.920
Unique ID: D044242
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D044242
Annotation: coord with specific fatty acid if pertinent
Scope Note: UNSATURATED FATTY ACIDS that contain at least one double bond in the trans configuration, which results in a greater bond angle than the cis configuration. This results in a more extended fatty acid chain similar to SATURATED FATTY ACIDS, with closer packing and reduced fluidity. HYDROGENATION of unsaturated fatty acids increases the trans content.
Entry Term(s): Trans Fatty Acid; Trans-Fatty Acids
Previous Indexing: Fatty Acids (1968-2003)
See Also: Linoleic Acids, Conjugated
