Biochemical Composition and Lipid Compositional Properties of the Brown Alga Sargassum horneri

Abstract

Biochemical composition of bro\VIl alga Sargassum horneri was investigated by determination of moisture, protein, carbohydrate, ash, simple lipids and glycolipids. Fatty acid composition of simple lipids and glycolipids was determined by gas chromatography. The algal specimens were collected in two different months, January (sample-I) and February (sample-2). Moisture contents were 86.94 and 87.00% in sample-l and sample-2, respectively. Protein, carbohydrate and ash contents were 22.94,19.93 and 32.00% of the dry sample-1, respectively, while the contents of the dry sample-2 were 21.96, 20.81 and 33.58%, respectively. Glycolipids were 1.38 and 1.96% of the dry sample-l and sample-2, respectively, whereas 2.45 and 2.75% when the samples were digested with the abalone Haliatis discus enzyme. Of the glycolipids obtained, MGDG, DGDG and SQDG were nearly 15, 15 and 68%, respectively

Comparative assessment of antioxidant activity and biochemical composition of four seaweeds, Rocky Bay of Abu Qir in Alexandria, Egypt

“…P. pavonia (20.4% ± 0.4) and T. atomaria (19.5% ± 0.7) was recorded the highest value in carbohydrate contents, while the lowest value showed with C. elongate (6.7% ± 0.5) and J. rubens (6.4% ± 0.4). Similar values were found in the brown alga Sargassum horneri (19.93% DW) (Hossain et al, 2003). These variations may be due to the species difference, growth stage of each species, habitat, metabolic preferences, and photosynthetic activity (Pádua et al, 2004).…”

Isolation of the Molecular Species of Monogalactosyldiacylglycerols from Brown Edible Seaweed Sargassum horneri and Their Inhibitory Effects on Triglyceride Accumulation in 3T3-L1 Adipocytes

“…This result agreed with Terasaki et al and Airanthi et al, who reported that 16:0 is the major FA in the total lipids of the same species. The major unsaturated fatty acids (UFAs) found in our study were C 18 UFAs [including 18:3(ω-3), 18:2(ω-6), and 18:1(ω-9)], which differed from the study by Hossain et al, who reported that C 20 UFAs are the major UFAs in this species. The FA composition is influenced by species , and environmental factors. − Seasonal variation is an important factor for the difference in polyunsaturated fatty acid (PUFA) species.…”

Chemical Composition, Nutritional Value, Bioactive Compounds Content and Biological Activities of the Brown Alga (Sargassum Subrepandum) Collected from the Mediterranean Sea, Egypt

“…They're crucial in commercial applications since they've become the focus of their study (El-Gamal, 2020;Elhassaneen et al, 2020 andFayez, 2021). For example, members of Sargassum genus represent valuable sources of several compounds including proteins, lipids, minerals, essential fatty and amino acids, and bioactive compounds (Hossain et al, 2003;El-Gamal, 2020 andRushdi et al, 2020). Polysaccharides, which include alginates, cellulose, and sulfated polysaccharides like fucoidans and laminarins, are also important components.…”
