Dr. Andy Galpin here we're back with another episode of five minute physiology where I take important topics from things like contrition exercise strength and conditioning and physiology and break them down and give you the needy greedy in five minutes or less today's topic lactate metabolism like they took my favorite molecules of all time because you can't read a magazine go to the gym reflect a football game without hearing someone talked about lactic acid buildup and are clearing the lactate out the day after a hard workout with your still sore or some nonsense like that and
it makes me laugh makes me feel bad for Portal active because everyone hates it right it's the bane of your existence to some reason why you failed so I wanted to make this short video to help you understand a little bit more about lactate so you understand what it actually is and you can stop blaming it for all your crappy problems your athletic problems and now I'm just gonna give you a quick shot of in this video if you this excited to hear more about a check out the 25 minute remaining 45 minute physiology videos
I mean I liked it but I understand was basically happening here have to realize that black CD is is a byproduct of metabolism so it's only being generated in other words when you break down glucose for fuel ok glucose is basically the same word as sugar or carbohydrate in this sense right and and in this particular talk we're talking about human skeletal muscle on exercise but we do that we're seeing here is carbohydrate is the word itself carbon and hydrate you can see from the picture here what I'm talking about is glucose specifically is a
six carbon chain so it's six carbons and six waters garbo yeah when I break down glucose for energy that process to call glycolysis ok it splits into two separate three carbon molecules called pyruvate now I make a little bit energy here but I had to invest some into it to get there so in other words I spent $5 I made $10 so I net gain five bucks now what you're gaining this particular cases some energy used to form a molecule called Google ATP ATP is the energy currency for all of biology human not human does
it really matter fact it's the same currency they using your red blood cells to generate energy your brain your skeletal muscle so you can see we make a little bit ETP right over here in the corner ok now we realize that we spent five we gained 10 we didn't $5 I can't live a $5 so we're not really trying to make ATP here we're trying to make pyruvate so that we can use that to make them more EGP later if we have oxygen available we can ship the pyruvate to the mitochondria that can be converted
into another little molecule that can go through thing called the TCA or citric acid cycle then go on to electron transport chain and that'll generate up to launch of ATP in fact it's probably 10 or 20 for the ATP created here and we went through glycolysis and the very beginnings this is the real endgame unfortunately this process doesn't work if i dont have the option is there is a requirement to go in the mitochondria and that's a requirement of course of a row vector oxidative metabolism so what your body says it's ok look what all
do is start shifting pyruvate over to something else now we have to understand she is what hydrogen is kinder gentler often referred to as a proton which is H plus thats asset so pH at which stands for potential hydrogen in other words if you have a lot of free-floating acid a free-floating hydrogen you are acidic ok so you start taking your pyruvate East are saying year ago I know of dinner in a bunch of acid picture yourself on that awful paradigm bike right that's in our house we have a saying that there's no winning with
your time only losing its the worst exercising every its awesome adjustments picture yourself you're on the air and I you doing something like twenty seconds as hard as you can twenty seconds off and you do ten rounds out or something like we did the other day and you generate a bunch of asset what you can do the start attaching that asset to the pyruvate now because it's not free floating around it doesn't cause an acidic environment when we take a pyruvate and attach an H plus two hydrogen protons we call that new molecule liked it
really is it's a pirate but that's holding on to higher than for you so not only is likely not causing all of your problems don't blame it for all your weekend standards it's actually being a buffer in other words it's stopping you from becoming acidic because it is holding on to a hundred and proved I can also learn because it is simply it is just pyruvate with hydrogen if I can bring some 02 into the arena I can combine a couple of hydrogens with that option I just brought in and make h2o and so I
can pure hydrogen back off of the lactate combined with a to make water and it once I've left the hydrogen I'm not back in my pyruvate state which is an amazing former sugar it can also be used as a homeowner signaling molecule to tell the rest of your body and other tissues for a system what's going on so we can ship lactate to other exercising muscles that aired I don't burn really hard on my qualms I can ship lactate to say my shoulders or something like that they can strip the hydrogen by combining with oxygen
and make them give themselves some free sugar we do the same thing at the heart and the same thing actually what the liver in a process called the quarry cycle we actually go through gluconeogenesis and we take to lactate combining together and make a brand-new glucose molecule what some of the recent research is actually showing is at your brain will do the same thing so your brain that we know primarily runs off of glucose metabolism and since the lactate is basically a broken down glucose if we have watched in our brain we can combine it
make water make pyruvate and power your brain this is probably why we know that things like cognitive function memory are improving kids or people taking final exams Sams or perform better job when you work out really hard you are directly creating lactate which directly fuels your brain many questions about this let me know on social media at the Dr NE Galpin if not on my website you can go to my website to check out more of these times of videos anti-government dot com
