Glucogenic Amino Acids

DOUGLAS C. HEIMBURGER MD, in Handbook of Clinical Nutrition (Fourth Edition) , 2006 The major aim of protein catabolism during a state of starvation is to provide the glucogenic amino acids (especially alanine and glutamine) that serve as substrates for endogenous glucose production (gluconeogenesis) in the liver. In the hypometabolic/starved state, protein breakdown for gluconeogenesis is minimized, especially as ketones become the substrate preferred by certain tissues. In the hypermetabolic/stress state, gluconeogenesis increases dramatically and in proportion to the degree of the insult to increase the supply of glucose (the major fuel of reparation). Glucose is the only fuel that can be utilized by hypoxic tissues (anaerobic glycolysis), by phagocytosing (bacteria-killing) white cells, and by young fibroblasts. Infusions of glucose partially offset a negative energy balance but do not significantly suppress the high rates of gluconeogenesis in the catabolic patient. Hence, adequate supplies of protein are needed to replace the amino acids utilized for this metabolic response. In summary, the two physiologic states represent different responses to starvation. The hypometabolic Continue reading >>

    cloudy pee on keto? (Reps)

    hey guys, just started a keto diet for cutting and kept my water intake about the same, if not then more (to supress hunger). Yet my pee seems to be yellow and cloudy, and not clear like water as when i was bulking. Any idea why?

  • Can Glucose Can Be Used To Make Fatty Acids?

    As evident by many sugar-laden soda pop "potbellies" of North America, lipogenesis can obviously occur from drinking and eating too much sugar (1). Wouldnt it be just grand to reverse the process and be able to lose all that fat via gluconeogenesis? Unfortunately mammals do not have the ability to synthesize glucose from fats (1). The fact is that once glucose is converted to acetyl coA there is no method of getting back to glucose. The pyruvate ...

Read more on the ‘about’ page) Ever since I started my ketogenic lifestyle I’ve been experiencing higher energy levels. Basically I have the same increased energy from the minute I wake up at ~7 A.M. up until I go to sleep at 2 A.M. at night. No post-prandial (after-meal) fatigue and no sleepiness during the day. It’s been quite amazing because during my ent ...
