Figure 7.
Spectrum of 3-hydroxyacyl-CoAs generated by the degradation of the four major groups of plant fatty acids through the β-oxidation cycle. All the potential 3-hydroxyacid moieties ranging from six to 14 carbons are incorporated into plant peroxisomal PHAs, except for H10:2 (undetectable) and H10:1 (trace amount) (indicated in small italic letters). It is hypothesized that the PhaC1 synthase cannot use 3-hydroxyacyl-CoAs having a double bond at the Δ4 position.
