Abstract
Hemoglobin je kompleksni protein prisutan u crvenim krvnim stanicama i igra ključnu ulogu u transportu kisika i ugljikovog dioksida u organizmu. Sastoji se od četiri podjedinice (dvije alfa i dvije beta podjedinice - α2β2), pri čemu svaka podjedinica sadrži mjesto za vezanje kisika, omogućujući učinkovit prijenos kisika iz pluća do tkiva i organa. Alosterija, važan biokemijski koncept, opisuje promjene u strukturi proteina koje utječu na njegovu funkciju. Kod hemoglobina, alosteričke promjene mijenjaju sposobnost hemoglobina za vezivanje i otpuštanje kisika. To znači da hemoglobin može prilagoditi svoju aktivnost ovisno o uvjetima u okolišu, kao što su pH i koncentracija CO2. Jedan od najpoznatijih primjera alosterije u hemoglobinu je Bohr efekt, gdje promjene u pHvrijednosti okoline utječu na afinitet hemoglobina za kisik. Ovaj mehanizam omogućava hemoglobinu da isporučuje kisik gdje je najpotrebniji u tijelu. Osim toga, hemoglobin može biti moduliran egzogenim faktorima poput organskih fosfata i 2,3-bisfosfoglicerata (BPG).
Abstract (english)
Hemoglobin is a complex protein present in red blood cells and plays a key role in the transportation of oxygen and carbon dioxide in the body. It consists of four subunits (two alpha and two beta subunits - α2β2), with each subunit containing a binding site for oxygen, enabling efficient transfer of oxygen from the lungs to the tissues and organs. Allosterism, an important biochemical concept, describes changes in the protein's structure that affect its function. In the case of hemoglobin, allosteric changes alter its ability to bind and release oxygen. This means that hemoglobin can adjust its activity depending on environmental conditions, such as pH and CO2 concentration. One of the most well-known examples of allosterism in hemoglobin is the Bohr effect, where changes in the pH of the environment influence hemoglobin's affinity for oxygen. This mechanism allows hemoglobin to deliver oxygen where it is most needed in the body. Additionally, hemoglobin can be modulated by exogenous factors such as organic phosphates and 2,3-bisphosphoglycerate (BPG).
