Abstract
from the obtained results it concluded that high protein diet (casein, soy) affect on brain metabolism as it increases serotonin and dopamine level from precursor tryptophan, tyrosin and phenylalanine which is responsible for mood and appetite regulation.
Also the result indicated that affect of high protein diet (casein, soy) decrease FAS activity (Fatty Acid Synthetase) which is rate limiting enzyme of lipogensis so leads to adecrease in denovo synthesis of free fatty acid, adecrease in fat accumulation and adecrease in body weight.
Also the result indicated that the affect of high protein diet (casein, soy) increase ketone bodies level (B-HBA, AcAc) which is the fuel source of brain in the fasting state in case of absence of the main source of energy (glucose) due to the brain cannot use fat as source of energy and ketone bodies have role in satiety regulation.
Morever, high protein diet (casein, soy) increases Succinic dehydrogenase activity (SDH), glucose -6- phoshate dehydrogenase activity which is rate limiting enzyme of pentose phosphate pathway (PPP) and citric acid cycle( CAC) that responsible for glucose oxidation and energy demand that main source of energy to brain and increase glucose from non CHO source as glucuneogensis.
