Fig. 3From: From low to high latitudes: changes in fatty acid desaturation in mammalian fat tissue suggest a thermoregulatory roleHistogram of a desaturation (∆9-DI) and b double bond index (DBI) of terrestrial (TE), semi-aquatic (SA), and fully-aquatic (FA) mammals. DBI has been calculated using all monounsaturated and polyunsaturated fatty acids, whereas ∆9-DI was calculated using only endogenous fatty acidsBack to article page
