Background:Polyhydroxyalkanoates (PHAs) are the current biopolymers, or biodegradable polymers whose applications for replacing plastics are under research. PHA is produced in different bacteria by fermentation. The enzymes, PHA synthases, use coenzymeA thioester of (R)-hydroxyfatty acids as substrate.
Query:1. What are (R)-hydroxyfatty acids?
2. What is the structure of "coenzymeA thioester of (R)-hydroxyfatty acids?
Thank you for all your help. Greatly appreciate it.
