Fatty acid composition of lizard tissue lipids and the effects of estradiol on serum free fatty acids.
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.
