In the biosynthesis of S-adenosylmethionine (SAM), the amino acid methionine undergoes an enzyme-catalyzed reaction with ATP to give SAM and triphosphate. This is one of only two known biochemical reactions in which triphosphate serves as a leaving group. Give the curved arrow mechanism for this reaction, assuming it is an SN2 process. Note, adenine is abbreviated as

Aluminum–lithium (al-li) alloys have been developed by the aircraft industry to reduce the weight and improve the performance of its aircraft. a commercial aircraft skin material having a density of 2.47 g/cm3 is desired. compute the concentration of li (in wt%) that is required.

Listenbase your answer to the question on the information below. nuclear radiation is harmful to living cells, particularly to fast-growing cells, such as cancer cells and blood cells. an external beam of the radiation emitted from a radioisotope can be directed on a small area of a person to destroy cancer cells within the body. cobalt-60 is an artificially produced radioisotope that emits gamma rays and beta particles. one hospital keeps a 100.0-gram sample of cobalt-60 in an appropriate, secure storage container for future cancer treatment. which choice represents the correct product for the beta decay of the co-60? fe-60ni-60fe-61ni-61
