Document Summary
Gluconeogenesis is turned on full time in cats. Low km, so enzyme is (cid:498)substrate-saturated(cid:499) at normal blood glucose concentrations, promoting steady. Glucokinase in humans regulates fluctuating levels of glucose. Glycerol from fats, if being used as a primary source of energy. High km, so enzyme activity automatically increases as blood glucose concentration rises. Alanine, asparate, glutamate, etc. of all carbons convertible. Threonine, phenylalanine, isoleucine, etc. partially convertible (one part is glucogenic, other is not) 3 carbons, will not be used to make acetyl coa, will fill in for missing glucose. Red blood cells do not have mitochondria need glucose as an energy source. Gla gamma linoleic acid present in evening primrose oil, black current seed oil, and borage oil. Need a spectrum of fatty acids from marine sources dog, cats are unable to convert linoleic acid to arachidonic acid and must receive arachidonic acid in the diet.
