How are elements synthesized
WebThe 26 heavier elements we know of so far, going up to 118 protons, were synthesized in nuclear reactors or particle accelerators, effectively created from the pieces and energy of other elements. Scientists pursue these new superheavy elements to … WebModular polyketide synthases (PKSs) are polymerases that employ α-carboxyacyl-CoAs as extender substrates. This enzyme family contains several catalytic modules, where each module is responsible for a single round of polyketide chain extension. Although PKS modules typically use malonyl-CoA or methylmalonyl-CoA for chain elongation, many …
