“…Nannochloropsis spp. contain phenolic acids (chlorogenic, caffeic, gallic, protocatechuic, hydroxybenzoic, syringic, vanillic, and ferulic acids) with free radical scavenging capacity, antifungal activity, and other in vitro activities [ 57 , 126 ]. These phenolics may contribute to the putative protective effects of the whole biomass against diabetes risk factors.…”

Marine and freshwater algae and their products are in growing demand worldwide because of their nutritional and functional properties. Microalgae (unicellular algae) will constitute one of the major foods of the future for nutritional and environmental reasons. They are sources of high-quality protein and bioactive molecules with potential application in the modern epidemics of obesity and diabetes. They may also contribute decisively to sustainability through carbon dioxide fixation and minimization of agricultural land use. This paper reviews current knowledge of the effects of consuming edible microalgae on the metabolic alterations known as metabolic syndrome (MS). These microalgae include Chlorella, Spirulina (Arthrospira) and Tetraselmis as well as Isochrysis and Nannochloropsis as candidates for human consumption. Chlorella biomass has shown antioxidant, antidiabetic, immunomodulatory, antihypertensive, and antihyperlipidemic effects in humans and other mammals. The components of microalgae reviewed suggest that they may be effective against MS at two levels: in the early stages, to work against the development of insulin resistance (IR), and later, when pancreatic -cell function is already compromised. The active components at both stages are antioxidant scavengers and anti-inflammatory lipid mediators such as carotenoids and -3 PUFAs (eicosapentaenoic acid/docosahexaenoic acid; EPA/DHA), prebiotic polysaccharides, phenolics, antihypertensive peptides, several pigments such as phycobilins and phycocyanin, and some vitamins, such as folate. As a source of high-quality protein, including an array of bioactive molecules with potential activity against the modern epidemics of obesity and diabetes, microalgae are proposed as excellent foods for the future. Moreover, their incorporation into the human diet would decisively contribute to a more sustainable world because of their roles in carbon dioxide fixation and reducing the use of land for agricultural purposes.

“…Plants contain a large variety of phenolic derivatives including simple phenols, benzoic acid derivatives, phenylpropanoids, flavonoids, tannins, stilbenes, lignans, and lignins [ 84 ]. The phenolics from terrestrial sources have been well studied, but information on aquatic species is limited [ 2 ]. The natural production of phenolic compounds in marine organisms is related to environmental factors, such as salinity, UV radiation, nutrient availability, and temperature [ 46 ].…”

“…Marine macroalgae phenolics vary from simple molecules such as phenolic acids to highly complex compounds such as phlorotannins (PHT). Some phenolic compounds, such as bromophenols and PHT have been reported exclusively in marine sources [ 2 , 46 ]. PHT, assembled through polymerization of phloroglucinol units, are found in high amounts in brown algae [ 55 ].…”

“…With the increase in the field of health-based research these new molecules are gaining more importance. Modern dietary habits and lifestyle in developed countries have resulted in an increasing number of diseases such as type 2 diabetes mellitus, obesity, metabolic syndrome, cancer, or neurodegenerative diseases [ 2 ]. Bioactive components from natural sources with an ability to contribute to the overall health have become an interesting alternative to potentially harmful synthetic ingredients.…”

The oceans have been the Earth’s most valuable source of food. They have now also become a valuable and versatile source of bioactive compounds. The significance of marine organisms as a natural source of new substances that may contribute to the food sector and the overall health of humans are expanding. This review is an update on the recent studies of functional seafood compounds (chitin and chitosan, pigments from algae, fish lipids and omega-3 fatty acids, essential amino acids and bioactive proteins/peptides, polysaccharides, phenolic compounds, and minerals) focusing on their potential use as nutraceuticals and health benefits.

“…Recently, there is increased interest in natural products and bioactive compounds as alternatives to synthetic substances. Marine algae are considered as an excellent source of bioactive compounds endowed with ingenious structure and potential biological activities 1 , such as antioxidant 2 , antimicrobial 3 , antifungal 4,5 , antiviral 6 , antidiabetic 7 , anti-inflammatory 8,9 and anticancer activities. 10,11 Moreover, these health benefits have been partly attributed to the phenolic contents.…”

their bioactive compounds are available in markets as anti-viral foods in assisting body's specific immune regulatory response. 12 In addition, it has been proved that applications of carrageenan gels from Chondrus crispus may block the transmission of the human immunodeficiency virus (HIV) as well as other sexually transmitted diseases (STD) viruses such as gonorrhoea, genital warts and the herpes simplex virus (HSV). 15 The red algae Chondrus crispus commonly called Irish moss or carrageen moss and Mastocarpus stellatus also called Cluimhin Cait (cats' puff), carrageen, or false Irish moss are found in the marine environment and traditionally used to cure for colds, sore throats, chest infections including tuberculosis. 16 Algeria is characterized by an extensive coastline and a phenomenal algal biodiversity. However, data on pharmacological potential of their bioactive secondary metabolites are very scarce. Hence, the current study aimed to assess the biological activity including antioxidant and antibacterial capabilities of three (03) red algae (Asparagopsis taxiformis, Hypnea musciformis and Corallina elongata) collected from Algerian West Coast (Oran). Materials and Methods Algal species collections Marine red algae were collected from Algerian West Coast (Oran) during March 2019. The algal species were identified by experts in these fields, using standard literature and taxonomic keys. The collected algal samples were cleaned well with seawater to remove impurities matter such as epiphytes, sand particles, The seaweeds were transported to the laboratory in sterile polythene bags and were washed with distilled water several times, spread on plates at room temperature and in the dark for three weeks. Dried samples were cut
