Reactive Attachment Disorder in Adults - Discovery …

WebThe cytoplasm of liver cells contain an enzyme called alcohol dehydrogenase (ADH) that catalyzes the oxidation of ethanol to acetaldehyde (Figure 1.11). The oxidation occurs when ethanol binds to a site on the ADH enzyme and loses some electrons in the form of H atoms. Actually ethanol gives up 2 H atoms to another molecule that also binds to ADH. WebAlcohol dehydrogenase (ADH) catalyzes the oxidation of ethanol (CH3CH2OH) to acetaldehyde, which is then fed into pathways to make fatty acids or to be used as a fuel source. The human body can therefore tolerate a certain amount of ethanol. However, the body cannot tolerate methanol (CH3OH). reactive world vs living world
