Inability of the cat to desaturate essential fatty acids
Open accessAbstract
MOST vertebrate species require some dietary source of essential fatty acids (EFAs)1,2. A wide range of naturally occurring polyunsaturated fatty acids have been shown to exhibit EFA activity, but they can be classified into two homologous series characterised by the position of the terminal double bonds relative to the methyl (omega) carbon atom. The ω6 series of EFAs all have double bonds in the ω6 and ω9 positions, the ω3 series in the ω3, ω6 and ω9 positions. The metabolic interrelationships of the members of each series are shown in Fig. 1. The naturally occurring 18-carbon parent compounds for each series are linoleic acid (18:2 ω6) and linolenic acid (18:3 ω3) and EFA requirements are usually stated in terms of either or both ot these parent EFAs (p-EFAs)1,3.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
