Internal rearrangement (Isomerization, and diminations Another common type of cellular rean is an intramolecular rearrangement, in which redistribution of es result in isomerizati transposition of double bonds, or as trans rearrangement of double bonde. + An ex. of Isomorization is the formation of fructose. 6 phosphate fry-Oxels of Monounsaturaded fatty and. Here oleic aud, Olevyl CoA (49) is wied as example. رو Oxdin requires an additional enzyme, envyl-CoA isornerare, to reposition the double bond, wnverting the cis isomer to a trans Isomer, a normal Intermediate, Boxdn. Gharp Transfer Reaction The transfer of acyl, glycosyl, and phosphoryl gps from one nucleophile to anotha is common in Ining cells. Acyl gpitransfer generally involves the addition of a nucleophele to the Carbonyl carbon of an acyl gp to form a tehahedred Intermediate. thaphang! go transfer man When a nudiophile attacks the destrophile phosphorous atom. ATP, a relatively stable protarovadent Struthere is formed as a rean intermediate with deportiere of the leaving gp (ADP), the transfer of a phaphoryl gp is complete The large family of armymes that catalyse phosphoryl group transfew with ATP as kinein, to move). donor Dove called Kinder (greek Herokinzue, for ex. moves" to phosphory! gp from ATP to glucose- phosphoryl gp transfer rean When a nudiophile attacks the electrophilic phosphorous atom in ATP, a relatively stable pentazovalent Structione is, formed as a rean intermediate with depoortuere of the leaving gp (ADP), the transfer of a phosphoryl gp is complete -The large family of enzymes that catalyze phosphoryl group banstou with ATP as donor kinein, to move"). core. called Kinases (greek Hexokinase, for ex. moves" to phosphoryl gp from ATP to glucose.
