Zation chain length

A specialty class of carboxyl containing elastomers are the telechelic ionomers. In these systems the carboxyl functionality terminates both ends of the polymer chain. Such polymers range in molecular weight from 1500 to about 6000. These materials can be prepared via several synthetic routes involving anionic or free radical initiated polymeri-zation(32-34). Recently, telechelic sulfonate ionomers of poly-isobutylene have been synthesized(35). These systems offer an unusual opportunity to assess the influence of chain length, chain architecture, cation type, and the Influence of polar additives on ionomer properties. 

Carnitine acyltransferases are involved in the transfer of acyl groups from acyl-CoAs to L-camitine i.e. in the reversible conversion of acyl-CoA into acylcamitine. Th enzymes have a wide and overlapping chain-length specificity and a range of cellular loc zations and metabolic functions. The best characterized carnitine acyltransferases are the mitochondrial carnitine palmitoyltransferases (CPT EC 2.3.1.21) flie CPTI and CPTII. The latest progress and current view of the stmctural, functional, regulatory and...
