    PATHWAY OF AMINO ACID

    METABOLISM IN THE

    POSTABSORPTIVE STATE -> AFTER A MEAL

  • 8/18/2019 Fed and Fasting

    13/15

    Blood-glucose level dropsafter several hours afterthe meal

    - > decrease in insulinsecretion

    -> rise in glucagon

    secretion Low blood-glucose level

     -> stimulates glucagonsecretion of α-cells of thepancreas

    EARLY FASTING STATE

    14/15

    FIRST PRIORITY

    -> provide sufcient glucose to brain and other tissues that aredependent on it

    SECOND PRIORITY  

    -> preserve protein

    -> shit rom utilization o glucose to utilization o atty acids + ketonebodies

    -> mobilization o TAG in adipose tissues + gluconeogenesis by liver

    -> muscle shit rom glucose to atty acids as uel

    AFTER 3 DAYS OF STARVATION 

    -> liver orms large amounts o ketone bodies

    -> brain and heart start to use ketone bodies as uel

    AFTER SEVERAL WEEKS OF STARVATION 

    -> ketone bodies major uel o brain

    AFTER DEPLETION OF TAG STORES

    -> proteins degradation accelerates

    PROLONGED STARVATION
