“…Seasonal variations of total lipids, fatty acid composition, and fucoxanthin contents in details were investigated also for S. horneri [20]. In general, seasonal changes in content of lipids and their components, primarily PUFAs, in several species of red algae [33], green algae [34], and brown algae [20], [35]- [42] were presented. Comparative study of content of phospholipids and glyceroglycolipids [43], and variations fatty acids of these lipids [38] were performed for S. pallidum collected only in March and in August, at water temperature 2.9˚C and 23˚C respectively.…”

The present study describes the content of total lipids (TL), the main components of polar and neutral lipids (NL) and photosynthetic pigments (PSP) in edible seaweed Sargassum pallidum (Ochrophyta) from the Sea of Japan, Russia, in different months of the year, taking into account life cycle. Special attention was paid to the fatty acids (FAs) of total lipids as well as the accumulation of important polyunsaturated fatty acids (PUFAs) in glyceroglycolipids (GL) and reserve lipids in the seasonal cycles of growth. The content of TL strongly varied in the course of a year. The major lipid components were GL (20.3% -36.4%) and NL (19.8% -30.6%), while phospholipids (PL) were present in negligible amounts (3.2% -6.9%). Significant seasonal variations were observed in content all classes of lipids. The PUFAs prevailed in total lipids and the content of n-6 PUFAs was higher than n-3 PUFAs on all stages of life with the exception of vegetation period. Monogalactosyldiacylglycerols (MGDG) and digalactosyldiacylglecerols (DGDG) were rich in PUFAs and n-3 PUFAs were dominated among them independently of stages of growth. Saturated fatty acids (SFA) were dominated in sulfoquinovosyldiacylglycerols (SQDG). Triacylglycerols (TAG) and diacylglycerols (DAG) contained many PUFAs, especially n-6 PUFAs. Significant concentration 20:3 n-6 was in the triacylglycerols. The concentration of chlorophylls and carotenoids was increased with the growth and maturation of S. pallidum and reached maximum in period of highest day length and water temperature. The content of pigments decreased with the onset of short days and decreasing water temperatures. Nutritional value and benefit for health of human this alga were evaluated. The n-6/n-3 PUFAs ratio, nutritional quality index (atherogenic and thrombogenic indices, and ratio between hypocholesterolemic and hypercholesterolemic fatty acids) were low, suggesting a high nutritional value of S. pallidum throughout the year.

“…Currently, many studies have been carried out on the effect of temperature on the lipid composition of algae. The main mechanisms of thermal adaptation have been determined, including changes in the degree of unsaturation and carbon chain length of fatty acids (FAs) [ 2 , 3 , 4 ], the ɷ3/ɷ6 ratio of polyunsaturated fatty acids (PUFAs) [ 5 , 6 ], the content of individual classes of polar lipids as well as the content of neutral lipids [ 7 , 8 , 9 , 10 ]. However, separate studies of FA composition and composition of lipid classes do not provide a complete picture of the adaptive reorganization of the lipid matrix of cell membranes.…”

The effect of temperature and light intensity on the polar lipidome of endophytic brown algae Streblonema corymbiferum and Streblonema sp. in vitro was investigated. More than 460 molecular species have been identified in four glycoglycerolipids classes, five phosphoglycerolipids classes and one betaine lipid class. The lipids glucuronosyldiacylglycerol and diacylglyceryl-N,N,N-trimethyl-homoserine were found in the algae of the order Ectocarpales for the first time. A decrease in cultivation temperature led to an increase in the unsaturation level in all classes of polar lipids. Thus, at low temperatures, the content of 18:4/18:4 monogalactosyldiacylglycerol (MGDG), 20:5/18:4 digalactosyldiacylglycerol (DGDG), 18:3/16:0 sulfoquinovosyldiacylglycerol (SQDG), 18:3/18:3 and 18:3/18:4 phosphatidylglycerol (PG), 20:4/20:5 and 20:5/20:5 phosphatidylethanolamine (PE), 14:0/20:5, 16:0/20:5 and 20:5/20:5 phosphatidylcholine (PC), 20:5/20:4 phosphatidylhydroxyethylglycine and 18:1/18:2 DGTS increased. At high temperatures, an increase in the content of chloroplast-derived MGDG, DGDG and PG was observed. Both low and high light intensities caused an increase in 20:5/18:3 MGDG and 18:3/16:1 PG. At low light intensity, the content of DGDG with fatty acid (FA) 18:3 increased, and at high light intensity, it was with FA 20:5. The molecular species composition of extraplastid lipids also showed a dependence on light intensity. Thus, the content of PC and PE species with C20-polyunsaturated FA at both sn-positions, 18:1/18:1 DGTS and 16:0/18:1 phosphatidylinositol increased. Low light intensity induced a significant increase in the content of chloroplast-derived 18:1/16:1 phosphatidylethanolamine.

“…Polar lipids, such as phospholipids, glycolipids, and sulfolipids, are mainly structural components as part of all cell membranes with crucial function for the living processes. Triacylglycerols, which are nonpolar lipids, have storage and energy reservoir functions, and compose most of the seaweed's lipids (Gerasimenko et al 2010). Additionally, it can be found some unusual lipids in seaweeds that are characteristic of a particular genus or species (Kumari et al 2013).…”

The incidence of light in terms of quality and quantity into the aquatic ecosystem is an important factor determining the distribution and abundance of macroalgae. Ultraviolet radiation which is one of the most debated factors that can affect these responses can cause significant cellular damage through photooxidation and oxidative stress, resulting in several vital metabolic changes such as DNA replication, transcription and translation, growth rate and development, photosynthesis and respiration, and promotion of apoptosis. Based on the aforementioned information, the present study aimed to contribute to the knowledge of the effect of UV radiation on macroalgae by using Sargassum spp. as biological model by integrating diverse physiological, cellular defenses, biological activities, and proteomic approaches for understanding the impact and sensitivity of this stressor under laboratory conditions. The different responses of the seaweed were evaluated under PAR, PAR+UVA and PAR+UVB treatments. Physiological parameters showed little variation between the treatments suggesting that moderate UV radiation doses could regulate resistance responses through the activation of antioxidant defense system by production of UV-absorbing compounds with photoprotective function, such as phlorotannins, flavonoids, and carotenoids that could provide adaptive advantages for organisms exposed to UV radiation. Moreover, extracts from the treated algal material presented high antiviral potential, which may be related to the presence of phenolic compounds and sulfated polysaccharides in the tested extracts. Then, the species can be considered as a potential biotechnology source of natural bioactive compounds. In relation to the proteomic profile of S. filipendula, were identified 40 proteins differentially abundant with respect to the UV treatments, which were mainly related to photosynthesis (32%), energy metabolism (12%), carbohydrate metabolism (7%), ROS scavenging defense and stress related metabolism (7%). Proteomic results showed target proteins that could improve the ability of the species to adapt to UV exposure, contribuiting significantly in our understanding of the molecular mechanisms underlying stress tolerance. Additionally, composition and abundance of fatty acids, chlorophylls, and carotenoids of S. vulgare after exposure to different light qualities: SOX (low pressure sodium lamps as control), SOX+Blue, SOX+Green, SOX+Red, and SOX+UV, showed that SOX supplemented with UV radiation provoked the decrease of certain carotenoids. On the other hand, the content of certain fatty acids under these SOX treatments showed slighty variation under the different light qualities, presenting a high percentage of PUFAs; however, there is need to perform future researches that allow the establishment of light condition for the stimulation of these compounds from S. vulgare.
