title: Fatty acid composition of lizard tissue lipids and the effects of estradiol on serum free fatty acids.
abstract: Fatty acid analyses of lipids from lizard fat bodies, carcass, and blood serum were performed by GLC. Principal fatty acids from all three tissues were palmitate (16:0), stearate (18:0), oleate (18:1), and linoleate (18:2). Administration of estradiol to vitellogenic or non-vitellogenic lizards increased serum levels of non-esterified fatty acids, but had no effect on the fat body wet weights. Lizards receiving estradiol had a higher proportion of arachidonate and a lower proportion of oleate in their serum non-esterified fatty acids.
