Specificity of papaya lipase in esterification of aliphatic alcohols a comparison with microbial lipases
Abstract Straight‐chain saturated C4 to C18 alcohols and unsaturated C18 alcohols such as cis ‐9‐octadecenyl (oleyl) cis ‐6‐octadecenyl (petroselinyl), cis ‐9, cis ‐12‐octadecadienyl (linoleyl), all‐ cis ‐9,12,15‐octadecatrienyl (α‐linolenyl), and all‐ cis ‐6,9,12‐octadecatrienyl (γ‐linolenyl) alcoh...
