Vyvanse and AdderallâA Comparison. Vyvanse and Adderall are both amphetamines, a type of stimulant medicine. They work in much the same way. They stimulate the nervous system and increase the amount of neurotransmitters such as dopamine and norepinephrine in the brain. Adderall has been around longer than Vyvanse.
Aromatase, also called estrogen synthetase or estrogen synthase, is an enzyme responsible for a key step in the biosynthesis of estrogens. It is CYP19A1, a member of the cytochrome P450 superfamily (EC 1.14.14.1), which are monooxygenases that catalyze many reactions involved in steroidogenesis.
Lactase functions best within limited ranges of both temperature and pH in its given environment, making it dependent on both factors for it to perform this essential reaction. If lactase is rendered nonfunctional because of temperature or pH extremes, the breakdown of lactose stops.actase functions best between roughly 70 and 120 degrees Fahrenheit, or somewhere near or just above room temperature, with its function optimized at around 115 degrees Fahrenheit.
