The fatty acid desaturation and elongation reactions catalyzed by Trichoderma sp. 1‐OH‐2‐3 were investigated. This strain converted palmitic acid (16:0) mainly to stearic acid (18:0), and further to oleic acid (c9‐18:1), linoleic acid (c9,c12‐18:2), and α‐linolenic acid (c9,c12,c15‐18:3) through elongation, and Δ9, Δ12, and Δ15 desaturation reactions, respectively. Palmitoleic acid (c9‐16:1) and cis‐9
木霉菌催化的脂肪酸去饱和和延伸反应。研究了1-OH-2-3。该菌株主要将棕榈酸(16:0)转化为硬脂酸(18:0),然后进一步转化为油酸(c 9-18:1),亚油酸(c 9,c 12-18:2)和α亚麻酸(c 9,c 12,c 15-18:3)通过延伸,分别进行Δ9,Δ12和Δ15去饱和反应。棕榈油酸(Ç 9-16:1)和顺式9,顺式:由应变0 12-十六碳酸也从16产生。该菌株将正十三烷酸(13:0)转化为顺式9-十七碳烯酸和顺式9,顺式12-十七碳二烯酸,分别通过延伸和Δ9和Δ12去饱和反应形成。通过Δ9去饱和作用,菌株使反式-牛痘酸(t 11-18:1)和反式-12-十八烯酸(t 12-18:1)饱和。来自t 11-18:1的产物被鉴定为顺式-9,反式-11十八碳二烯酸和反式9,反式11十八碳十八烯酸的共轭亚油酸(CLA)。来自t 12-18:1的乘积被确定为顺式9,反式十二十八碳二烯酸。顺式-
