WebCovalent bonding at A'level. Cases where there isn't any difference from the simple view. If you stick closely to modern A'level syllabuses, there is little need to move far from the simple (GCSE) view. The only thing which must be changed is the over-reliance on the concept of noble gas structures. Most of the simple molecules you draw do in ... WebCovalent Catalysis. Covalent catalysis involves the formation of a covalent bond between the enzyme and at least one of the substrates involved in the reaction. Often times this involves nucleophilic catalysis which is a subclass of covalent catalysis. As seen in Section 7.1, several amino acid R-groups can serve as a nucleophile and are often ...
