Food Addit Contam Part A Chem Anal Control Expo Risk Assess . 2012 Jul; 29(8):1230-8. PMID: 22784192
Heated plant foods may contain compounds with adverse health effects (e.g. acrylamide). On the other hand, health-promoting compounds (e.g. antioxidants) have also been identified in such foods. Therefore, a baking...

Long-chain alkyl benzoates, e.g., lauryl 4-hydroxybenzoate, palmityl 4-hydroxybenzoate, and oleyl 4-hydroxy-3-methoxybenzoate, are formed in high to moderate conversion by lipase-catalyzed transesterification of the corresponding short-chain alkyl benzoates (0.3 to 1...

Biotechnol Bioeng . 2007 Oct; 99(5):1074-84. PMID: 17969136
Linear copolymeric polyesters (polyoxoesters) containing thioether functions [poly(3,3'-thiodipropionic acid-co-alpha,omega-alkanediols)] were formed in good yield by esterification of an equimolar mixture of 3,3'-thiodipropionic acid (4-thiaheptane-1,7-dioic acid) and 1,6-hexanediol (weight average molecular...

Appl Microbiol Biotechnol . 2006 Nov; 74(2):357-65. PMID: 17103159
Branched-chain copolymeric polythioesters (PTE) were formed in good yield (approximately 87%) by chemoenzymatic reactions including thiyl radical-induced addition of 1,6-hexanedithiol to the >C=C< double bond of dimethyl 1,18-octadec-9-enedioate and transthioesterification...

Linear copolymeric polythioesters [PTE; poly(alpha,omega-alkanedioic acid-co-alpha,omega-alkanedithiols)] were formed in good yield (approximately 69%) by thioesterification of 1,12-dodecanedioic acid with 1,6-hexanedithiol and 1,8-octanedithiol, respectively, catalyzed by immobilized lipase from Rhizomucor miehei...

Appl Microbiol Biotechnol . 2004 Mar; 64(6):800-5. PMID: 15048592
1- S-Mono-palmitoyl-hexanedithiol and 1- S-mono-palmitoyl-octanedithiol were prepared in high yield (80-90%) by solvent-free lipase-catalyzed thioesterification of palmitic acid with the corresponding alpha,omega-alkanedithiols in vacuo. Similarly, 1,6-di- S-palmitoyl-hexanedithiol and 1,8-di- S-palmitoyl-octanedithiol...
