 Okay, so welcome once again. As you can see, I will be talking about how do I memorize the different globin chains in a hemoglobin. So we all know that each hemoglobin is unique to from one another because of the different globin chains that can be found within it. So let us go straight to our discussion. So how do I memorize the different globin chains? But before we begin that, of course, there are different globin chains to start with. We have your alpha, okay? We have your alpha, your beta, your gamma, your delta, epsilon, and zeta. So these are the different globin chains that you can see within a hemoglobin. So first let us classify one from the other. So we all know that your globin are being encoded by two of your chromosomes, okay? By two of your chromosomes. That is chromosome 16 and chromosome 11, okay? Again, chromosome 16 and chromosome 11. So chromosome 16 is for actually for your alpha, okay? Chromosome 16, number 16 is for your alpha and your zeta, okay? Chromosome 16. And the rest here, beta, gamma, delta, epsilon is your chromosome 11, okay? Chromosome 11. And one very interesting fact is that your alpha globin contains 141 amino acids. Same thing with your zeta, 141 amino acids. And the rest of your beta, gamma, delta, epsilon does contain 146 amino acid. So 141, 141 for your alpha, 141 for your zeta, and 146 amino acids for your beta, gamma, delta, and epsilon. So let's go straight now on how do I memorize the different hemoglobin. So we all know that there are fetal hemoglobin and adult hemoglobin. So let us go and start with the first three fetal hemoglobin that is very much common. So let us enumerate them first. So we have here your goer. We actually have here your goer 1, your goer 2. I also have here my portland, okay? My portland. At the same time, okay, aside from portland, you do also have your hemoglobin F, okay? Your fetal hemoglobin, okay? Your fetal hemoglobin and your hemoglobin A, which is actually very much common when you are actually, when you, from birth, okay? And of course in adulthood, you already have the combination of your hemoglobin F, hemoglobin A, and another hemoglobin, which is your hemoglobin A2. So again, like what I was mentioning kanina, one challenge is how to memorize what globin chains that each of them contain, okay? So but before we dig into that, please remember that each hemoglobin, okay? Each of your hemoglobin contains, okay? They contain four, okay? They contain four globin chains, okay? Four globin chains, okay? Four globin chains. And one very important thing to remember here. The four globin chains is actually two identical pairs of your globin chains. Two identical pairs. So when I say two identical pairs, meaning to say, dalawang alpha, dalawang beta. So that makes up one hemoglobin. Pwede rin dalawang gama, or dalawang zeta. So that in itself would make up your hemoglobin, okay? So let's go to our goer one, goer two, Portland hemoglobin F, hemoglobin A, and your hemoglobin A2. So the thing that I will be discussing to you would somehow sound fun, sound silly, pero ganun talaga, that's how we memorize things better. So for goer one ayyan, so meron tayong kwento. Goer one dahil level one ka palang, everything is easy. So the things that you are actually gonna see here, okay? The globin chains here are easy, okay? Which is your epsilon, okay? Which is your epsilon, which is your epsilon and zeta, okay? So mean to say, two epsilon, two zeta would make up your goer one. Goer one, madali ang buhay, easy, kasi level one. Pero nung grade two ka, okay? Nung grade two ka, ikaw ay nata e, okay? So t, let's take the t and the two. Okay, goer two is actually your alpha and your epsilon. So nung grade two ka, ikaw ay nata e sa iyong pants. So goer two, you have two alpha and two epsilon. Two alpha, two epsilon. What about Portland? Okay, what about Portland? Sabi na nating ang Portland ay isang brand ng cemento. At pag isakang brand ng cemento, ang cemento ay matigas. At kung ikaw yan matigas ka, tigasin ka sa inyong kanto, tinatawag ka nating zega, okay? Isakang zega. So ibig sabihin that is one zeta, two zeta and two gama, okay? Isakang zega, okay? So let's just have a recap for the fetal hemoglobin first. So we have your life is easy, okay? One is easy, one is easy. Two nata e, okay? Three, okay? Third, for your Portland dahil tigasin ka, ikaw ay zega, okay? Ikaw ay zega, ikaw ay matigas, okay? So two zeta, two gama. So for the fetal hemoglobin, sabihin natin, for the fetal dahil maagapa, okay? Dahil maagapa, your fetal hemoglobin appears early maaga. So it has maaga, which is two alpha and two gama, okay? So let's just try to change how it is written. We have your two alpha plus two gama. So for the hemoglobin F, maaga, aga. For the hemoglobin A, for the hemoglobin A, ang tumanda ka na, okay? Gusto mo naman mag-ka, roon ng abs. So para mas madaling tandaan, ng adult, adult, okay? Adult hemoglobin, gusto mo mag-ka roon ng abs. So that is alpha and beta. Two alpha, two beta, that is your hemoglobin A, okay? Hemoglobin A, gusto mo mag-ka roon ng abs. Pero teka-teka, meron pang hemoglobin A2. One plus one is equal to two. Anong ginawa mo para makuha si two, ikaw ay nag-add. So that is alpha plus delta. So two alpha, two delta, you added one plus one is equal to two. Hemoglobin A2. So that's how I memorize it. So let's have a recap. So for hemoglobin F, hemoglobin F, maaga. So alpha, gama. For hemoglobin A, gusto mo mag-ka roon ng abs. Kasi adult ka na. So alpha and beta. Pero wait lang, wait lang, meron pang hemoglobin A2. Para natin makuha yung two, one plus one is equal to two. Anong ginawa mo nag-add ka. So alpha and delta. So please remember that this actually is two pairs. Two pairs of alpha, two pairs of gama. Two pairs of alpha, two pairs of beta. Two pairs of alpha, two pairs of delta. And the same thing goes with your Gover 1, Gover 2, and your Portland. So I hope that helps you memorize your hemoglobin chains better. So I hope to see you on my next video. So that's it for today. So that's it for today. So what? Thank you so much.
