A General Overview Of The Major Metabolic Pathways

A general overview of the major metabolic pathways Assistant Professor, Universidade FernandoPessoa Metabolism is the set of chemical rections that occur in a cell, which enable it to keep living, growing and dividing.Metabolic processes are usually classified as: catabolism - obtaining energy and reducing power from nutrients. anabolism - production of new cell components, usually through processes that require energy and reducing power obtained from nutrient catabolism. There is a very large number of metabolic pathways. In humans, the most important metabolic pathways are: glycolysis - glucose oxidation in order to obtain ATP citric acid cycle (Krebs' cycle) - acetyl-CoA oxidation in order to obtain GTP and valuable intermediates. oxidative phosphorylation - disposal of the electrons released by glycolysis and citric acid cycle. Much of the energy released in this process can be stored as ATP. pentose phosphate pathway - synthesis of pentoses and release of the reducing power needed for anabolic reactions. urea cycle - disposal of NH4+ in less toxic forms fatty acid -oxidation - fatty acids breakdown into acetyl-CoA, to be used by the Krebs' cycle. gluconeogenesis - glucose syn Continue reading >>

  1. Bulletproofer IRL

    First time poster but long time reader. I have been doing the bulletproof diet since January which includes BP Coffee each morning with unsalted grassfed butter from a local farm (I live in Ireland). I use upgraded beans and upgraded MCT oil.
    Everything was going fine until about 6 weeks ago. When I would drink BPC in the morning by about midday I would start to get a dull pinching like pain in my liver area. Very uncomfortable and worrying. I find on mornings if I don't have BP Coffee then I don't suffer that day.
    Also, and this is interesting: When I have the pain - if I eat starchy carbs such as rice then within 30 mins there is immediate relief from the pain. This leads me to believe this might be something to do with ketosis?
    Can anyone shed any light on this?

    Do you have refeed/protein fasting days every 4-7 days????
    Ketosis is stressfull on your liver! The liver is the organ that has to produce the ketone bodies. So after having you BPC this is exactly the time when you get into ketosis. and why the hell do you have starchy vegetables duriing the day when you are following the bulletproof diet?
    Before following it any longer go to a doctor who know about ketogenic diets and who can check you liver....

Connections Between Cellular Respiration And Other Pathways

So far, we’ve spent a lot of time describing the pathways used to break down glucose. When you sit down for lunch, you might have a turkey sandwich, a veggie burger, or a salad, but you’re probably not going to dig in to a bowl of pure glucose. How, then, are the other components of food – such as proteins, lipids, and non-glucose carbohydrates – broken down to generate ATP? As it turns out, the cellular respiration pathways we’ve already seen are central to the extraction of energy from all these different molecules. Amino acids, lipids, and other carbohydrates can be converted to various intermediates of glycolysis and the citric acid cycle, allowing them to slip into the cellular respiration pathway through a multitude of side doors. Once these molecules enter the pathway, it makes no difference where they came from: they’ll simply go through the remaining steps, yielding NADH, FADH​, and ATP. Simplified image of cellular respiration pathways, showing the different stages at which various types of molecules can enter. Glycolysis: Sugars, glycerol from fats, and some types of amino acids can enter cellular respiration during glycolysis. Pyruvate oxidation: Some type Continue reading >>

    I have started out for the third and final time on Keto on Monday.
    My weight has dropped 3 pounds in 4 days, but the Keto sticks are not changing colour (only started yesterday using them).
    How long does it take the average person to get into Ketsosis, I know there are a lot of variables to consider but I was wondering what people’s experience is?
    Before when I did this, the sticks were changing colour after 3 days.

    How long does it take the average person to get into Ketsosis, I know there are a lot of variables to consider but I was wondering what people’s experience is?
    The average person (someone who is insulin sensitive) could be in ketosis when they get up every morning.
    I started casually and it took about 2 days for me to get the first symptoms of carb withdrawal.

Fatty acid oxidation lecture - This biochemistry lecture explains the process of beta oxidation of fatty acids. This lectures explains the beta oxidation process of fatty acids step by step. beta-oxidationis the catabolic process by whichfatty acidmolecules are broken down in the cytosol in prokaryotes and in the mitochondria in eukaryotes to generate acetyl-CoA, which enters the citricacidcycle, and NADH and FADH2, which are co-enzymes used in the electron transport to generate ATP molecules. Beta oxidationof fatty acids takes place in the mitochondrial matrix for the most part. However, fatty acids have to be activated for degradation by coenzyme A by forming a fatty acyl-CoA thioester. For short and medium length fatty acids, they undergo this reaction in the mitochondria. When pancreatic lipase acts on the small lipid droplets, it breaks them down into freefatty acidsand monoglycerides, which are the two digestive products of lipids. These small units are able to pass through the intestinal mucosa and enter the epithelial cells of the small intestine. Where are fatty acids stored in the body? Fatty acidsare released, between meals, from the fat depots in adipose tissue, where they arestoredas triglycerides, as follows: Lipolysis, the removal of thefatty acidchains from the glycerol to which they are bound in their storage form as triglycerides (or fats), is carried out by lapses.

Fatty Acid Oxidation And Its Relation With Insulin Resistance And Associated Disorders

Fatty Acid Oxidation and Its Relation with Insulin Resistance and Associated Disorders Faculty of Medicine and Dentistry, 423 HMRB University of Alberta, Edmonton, Alberta T6G 2S2 (Canada) Alterations in muscle fatty acid metabolism have been implicated in mediating the severity of insulin resistance. In the insulin resistant heart fatty acids are favored as an energy source over glucose, which is thus associated with increased fatty acid oxidation, and an overall decrease in glycolysis and glucose oxidation. In addition, excessive uptake and beta-oxidation of fatty acids in obesity and diabetes can compromise cardiac function. In animal studies, mice fed a high fat diet (HFD) show cardiac insulin resistance in which the accumulation of intra-myocardial diacylglycerol has been implicated, likely involving parallel signaling pathways. A HFD also results in accumulation of fatty acid oxidation byproducts in muscle, further contributing to insulin resistance. Carnitine acetyltransferase (CrAT) has an essential role in the cardiomyocyte because of its need for large amounts of carnitine. In the cardiomyocyte, carnitine switches energy substrate preference in the heart from fatty acid Continue reading >>

    Although I don't look for ketosis, I have done a lot of research and they most common thing that many of my weight loss friends use is a stick that is similar to a EPT (pregnancy test). A few of them said they purchase them from walmart, however I've never seen them there. A lot of them also order them online, so I'm sure if you do some online research you can find them. I hope this helps. Best wishes!!

    The ketosis sticks do not work for everyone....I 've lost over 100 lbs on Atkins and they never changed color for me. They are also pretty costly.
    Key signs of ketosis are bad breath, a metallic taste in the mouth, foul smelling urine and thirst.

  • Oxidation Of Glucose

    Glucose oxidation is a chemical process that provides energy for an organism to carry out all of its required activities. During this process, glucose, a simple sugar molecule obtained from food, is broken down into carbon dioxide and water. This reaction releases energy and stores it in a chemical form for the cell to use. There are three separate stages of glucose oxidation: glycolysis, the citric acid cycle, and the electron transport system. ...
