    ..We conclude that an increase, not a decrease in fuel consumption, via an accelerated oxidation of fuels in the TCA cycle is involved in life span regulation; this mechanism may be conserved across phylogeny. ..

    ..In this way, the structural determinants of regioselectivity in FAT-1 and FAT-2 have been localized to two interdependent regions: a relatively hydrophobic region between the first two histidine boxes and the carboxyl-terminal region. ..

    ..These results indicated that the elongation and desaturation of fatty acids are integral to various phenomena such as ontogeny and lifespan and play important roles in fatty acid accumulation and consumption. ..
