Energy yield

Fatty acids are an important energy source, for they yield over twice as much energy as an equal mass of carbohydrate or protein. In humans, the primary dietary source of fatty acids is triacylglycerols. This lecture will describe the metabolism of fatty acids. The two main components of fatty acid metabolism are β oxidation and fatty acid synthesis. Upon completion of this lecture, you will understand that the fatty-acid breakdown reactions of β oxidation result in the formation of reduced cofactors and acetyl-CoA molecules, which can be further catabolized to release free energy.

I. Introduction An important aspect of nuclear reactor core analysis involves the determination of the optimal coolant flow distribution and pressure drop across the reactor core. On the one hand, higher coolant flow rates will lead to better heat transfer coefficients and higher Critical Heat Flux (CHF) limits. On the other hand, higher flows rates will also in large pressure drops across the reactor core, hence larger required pumping powers and larger dynamic loads on the core components.

The ¯uorescence resonance energy transfer parameter, f, is de®ned as the eciency of the energy transfer normalized by the quantum yield of the donor in the presence of acceptor. It is possible to characterize the ¯exibility of the protein matrix between the appropriate ¯uorescent probes by monitoring the temperature dependence of f. The intermonomer ¯exibility of the Ca-actin and Mg-actin ®laments was characterized by using this method at pH values of 6.5 and 7.4.
