What are the major fatty acids found in Scenedesmus obliquus BGP and Porphyridium cruentum oils?
Label:chem
Topic
Compares two microalgae species—S. obliquus BGP (green algae) and P. cruentum (red algae)—and evaluates their oil composition using GC-FID.
Answer
S. obliquus BGP oils are rich in C18 fatty acids (both saturated and unsaturated), with oleic acid (C18:1n-9) being the dominant monounsaturated fatty acid (28.6–38.7% of total fatty acids), followed by linoleic acid (C18:2n-6, 11.6–14.8%) and α-linolenic acid (C18:3n-3, 9.1–19.1%).
P. cruentum oils are characterized by high levels of long-chain polyunsaturated fatty acids (PUFAs), particularly arachidonic acid (C20:4, 23.6–34.8%) and eicosapentaenoic acid (C20:5, 8.1–11.7%), while C18 fatty acids are present in lower proportions (19.3–28.3%).
