“…During the year, PS content remained unchanged, whereas LPC content changed. Khotimchenko et al (1990) demonstrated that the most characteristic features of the Rhodophyta are dominance of PC among PLs. The PL classes PG, PI, PC, and PE were found in Porphyra imbilicalis, while Polysiphonia harveyi contained PG, PI, and PE.…”

“…The major PLs were PC (32 %), PS (30 %), and PG (12 %). A high level of PC and a low level of PE are typical of red algae (Khotimchenko et al 1990). It can be observed that PG, PE, and PI levels are roughly halved between winter and summer, contrary to PC whose level is doubled at the same seasons (% PC summer/% PC winter0 2.18±0.01) ( Table 4).…”

Seasonal composition of lipids, fatty acids, and sterols in the edible red alga Grateloupia turuturu

et al. 2012

Composition of lipids, sterols, fatty acids (FA), and phospholipids in the edible Rhodophyta Grateloupia turuturu from Britanny, France, was investigated over four seasons in order to identify compounds with potential benefits in health and nutrition. The lipid content was found to vary from 3.3 to 4.1 % dry weight. No marked variations were observed for glycolipids accounting for 42.3-46.8 %, whereas neutral lipids and phospholipids fluctuated from 20.1 % (summer) to 41.8 % (winter), and 11.2 % (winter) to 33.4 % (summer), respectively. Polyunsaturated FA of the total lipids were found from 20.4 % (winter) to 31.1 % (summer), including 20:5 ω3 acid as the major one (up to 16.3 % in summer). Phosphatidylcholine (20.0-43.7 %) and phosphatidylserine (24.6-37.5 %) were the dominant phospholipids in all seasons. Compounds of interest were identified in minor amounts such as squalene, α-tocopherol, phytonadione (vitamin K 1 ), cholesteryl formate, cholest-4-en-3-one, and cholesta-4,6-dien-3-one. Cholesterol was the major sterol with a lower content in spring and summer.

“…However, they are some of the main lipids in many organisms. It has been demonstrated in several studies and reviews that the most often encountered betaine lipid DGTS was detected in lipids from microorganisms, fungi, algae, lichens, and in lower vascular plants but not in flowering plants [12][13][14]. This last feature suggests that this lipid has significance for evolution and, according to some authors, plays the same role in cells of lower plants as PC in higher plants [14].…”

“…The lipid profiles of some algae, especially the red algae of the Gracilaria genus, are used to differentiate among the species based on the levels of C 20 polyunsaturated fatty acids, namely arachidonic acid (20:4n-6) and eicosapentaenoic acid (20:5n-3) 6) . Screening of marine macrophytes revealed that the composition of their polar lipids primarily reflects the taxonomic position of marine macrophytic algae 7) . The fatty acid composition of red, brown and green macrophytes, which belong to different taxonomic classes, orders or families and genera, has distinguishing features of value in taxonomic classification.…”

“…Although phospholipids are lesser components, their distribution in algae is more interesting for chemotaxonomic purposes. Khotimchenko et al 7) investigated the polar lipid composition of 49 species of marine macrophytic algae including Rhodophyta (red algae), Phaeophyta (brown algae) and Chlorophyta (green algae), and demonstrated that each division of seaweeds and each class of Phaeophyta and Chlorophyta had distinctive peculiarities in the composition of their phospholipids and other polar lipids. In the paper, they also demonstrated that Rhodophyta were the richest in PC, with a lesser amount of PG, and contained an unusual unsaponifiable phospholipid X 1 (a sphingophosphoinositol).…”

Lipid Class and Fatty Acid Composition of a Little-known and Rarely Collected Alga Exophyllum wentii Weber-van Bosse from Bali Island, Indonesia

The lipid class and fatty acid composition of a little-known and rarely collected alga Exophyllum wentii from Bali Island, Indonesia were determined for fresh and frozen-thawed samples using thin-layer chromatography, gas-liquid chromatography, and high-performance liquid chromatography. Glycoglycerolipids, which mainly consisted of mongalactosyldiacylglycerols (MGDG) and digalactosyldiacylglycerols (DGDG), were the predominant lipid components, accounting for 67% and 56% of the total polar lipid content in the fresh and frozen-thawed samples, respectively. Phospholipids, including phosphatidylcholines (PC) and phosphatidylglycerols (PG), were detected with lesser amounts in both samples (16 -17% of the total polar lipid content). Free fatty acids (FFA), sterols and triacylglycerols (TAG) were also detected in minor quantities; however, the FFA content in the frozen-thawed sample increased to up to 20% of the total lipid content, suggesting that hydrolysis of the membrane lipids had occurred. A crude enzyme preparation from the alga showed activities for hydrolyzing the acyl groups of the phospholipids and glycoglycerolipids. Palmitic acid (16:0) and arachidonic acid (20:4n-6) were the major fatty acids in both the total lipid and in individual polar lipid classes as well as the dominant fatty acids released from the membrane lipids by enzymatic hydrolysis. The high level of 20:4n-6 (29%) in the total lipid and the presence of considerable amounts of PC (11% of the total polar lipid) and PG (6.2%) support classification of E. wentii into the Division Rhodophyta.
