Happy Fun Fact Friday everyone!
This week’s fun fact looks at the genome of the domestic cat.
This article by Montague et al. (2014) compares feline biology and domestication with our kitties genetic signature.
Since cats are obligate carnivores, they are not able to synthesize certain essential fatty acids, such as arachidonic acid, and thus they have many genes for lipid metabolism.
Cats who were fed a diet rich in saturated and polyunsaturated fatty acids showed normal lipid plasma concentrations whereas in humans this diet could lead to coronary heart disease and atherosclerosis!
Furthermore, they share similar lipid metabolic pathways found in the genome of polar bears!
