All animals incur unavoidable metabolic costs associated with digesting food which take away from their net energy gains, a phenomenon is known as specific dynamic action (SDA). Interestingly, despite a century of inquiry, modern scientists cannot agree on exactly why this is. This review summarizes the history of physiological and nutritional inquiries into SDA, and discuses the various hypotheses that have been advanced to SDA throughout the decades

"Partitioning of carbon dominates intracellular fluxes in both photosynthetic and heterotrophic plant tissues, and has vast influence on both plant growth and development. Recently, much progress has been made in elucidating the structures of the biosynthetic and degradative pathways that link the major and minor pools of soluble carbohydrates to cellular polymers such as starch, heteroglycans and fructans. In most cases, the regulatory properties of these pathways have been elucidated and the enzymes involved have been investigated using reverse genetics approaches
