Choline acetyltransferase was demonstrated in nettles (Urtica dioica), peas (Pisum sativum), spinach (Spinacia oleracea), sunflower (Helianthus annuus) and blue--green algae by using a Sepharose--CoASH affinity column. The column effected a 1500-fold purification of the enzyme from nettle homogenates and was required for demonstrating activity in the other higher plants. Demonstration of the en...
Perfluoroalkyl acids (PFAAs) are a group of synthetic persistent chemicals with distinctive properties, such as high thermal and chemical stability, that make them suitable for wide range applications. They have been produced since the 1950s, resulting in global contamination environment wildlife. resistant to biodegradation tendency bio-accumulate organisms bio-magnify food chain. However, lit...
