WebBei einer Lactose-Intoleranz kannst Du Pflanzenmilch selber machen oder kaufen. Beim Backen kannst Du statt Maisstärke Flohsamenschalen oder Kartoffelmehl verwenden. Somit kannst Du auch weiterhin Deine Lieblingsrezepte essen und musst auf nichts verzichten. Wie stark die Symptome bei einer Intoleranz sind, ist von Mensch zu Mensch verschieden.
WebNational Center for Biotechnology Information eastpoint electrical contractors ltdLike allolactose, IPTG binds to the lac repressor and releases the tetrameric repressor from the lac operator in an allosteric manner, thereby allowing the transcription of genes in the lac operon, such as the gene coding for beta-galactosidase, a hydrolase enzyme that catalyzes the hydrolysis of β-galactosides into monosaccharides.
