“…Vitamin C, E, and B12 are present in high concentrations in some algae [10]; however, controversy exist regarding algal Vitamin B12 bioavailability, due to the presence of corrinoids (analog molecules to cobalamin) that do not possess the cobalt ions, and do not present B12 activity in humans [150]. Compared with other phylum, Phaeophyta contain relatively high content of total tocopherol, mostly as α-tocopherol, and Chlorophyta contained a high level of β-carotene [151].…”

“…Among carotenoids, fucoxanthin stands out because of its effects on antidiabetic, anti-obesity, and antioxidant capacity [71]. Fucoxanthin is a characteristic carotenoid of brown algae, including edible species such as U. pinnatifida and Hijikia fusiformis (Sargassum fusiforme) [151]. In addition, algae belonging to Phaeophyta contain higher amounts of fucosterol and polyphenol than other algae [151].…”

Type-2 diabetes mellitus (T2DM) is a major systemic disease which involves impaired pancreatic function and currently affects half a billion people worldwide. Diet is considered the cornerstone to reduce incidence and prevalence of this disease. Algae contains fiber, polyphenols, ω-3 PUFAs, and bioactive molecules with potential antidiabetic activity. This review delves into the applications of algae and their components in T2DM, as well as to ascertain the mechanism involved (e.g., glucose absorption, lipids metabolism, antioxidant properties, etc.). PubMed, and Google Scholar databases were used. Papers in which whole alga, algal extracts, or their isolated compounds were studied in in vitro conditions, T2DM experimental models, and humans were selected and discussed. This review also focuses on meat matrices or protein concentrate-based products in which different types of alga were included, aimed to modulate carbohydrate digestion and absorption, blood glucose, gastrointestinal neurohormones secretion, glycosylation products, and insulin resistance. As microbiota dysbiosis in T2DM and metabolic alterations in different organs are related, the review also delves on the effects of several bioactive algal compounds on the colon/microbiota-liver-pancreas-brain axis. As the responses to therapeutic diets vary dramatically among individuals due to genetic components, it seems a priority to identify major gene polymorphisms affecting potential positive effects of algal compounds on T2DM treatment.

“…The most abundant nutrients in seaweeds are non-starch polysaccharides and minerals. The lipid content of seaweeds is low (1%–5% of the weight of a dry weight (DW) sample); however, the lipids comprise many kinds of bioactives, such as n-3 and n-6 polyunsaturated fatty acids (PUFAs), chlorophylls, carotenoids, terpenoids, and sterols [14,15,16,17,18].…”

“…In addition to the pigments, seaweed lipids generally contain high levels of PUFAs, such as α-linolenic acid (18:3 n-3 , ALA), stearidonic acid (18:4 n-3 , SDA), and eicosapentaenoic acid (20:5 n-3 , EPA) as n-3 PUFAs, and arachidonic acid (20:4 n-6 , ARA) as an n-6 PUFAs [14,16,18,29]. Many studies, including substantial epidemiological, case-control, clinical, genetic, and nutrigenetic approaches, demonstrate a reduction in cardiovascular disease risk from intake of n-3 PUFAs, such as EPA and docosahexaenoic acid (22:6 n-3 , DHA), which are the active forms of n-3 PUFAs [16,30].…”

Variation in Lipid Components from 15 Species of Tropical and Temperate Seaweeds

et al. 2019

The present study describes the variation in lipid components from 15 species of seaweeds belonging to the Chlorophyta, Ochrophyta, and Rhodophyta phyla collected in tropical (Indonesia) and temperate (Japan) areas. Analyses were performed of multiple components, including chlorophylls, carotenoids, n-3 and n-6 polyunsaturated fatty acids (PUFAs), and alpha tocopherol (α-Toc). Chlorophyll (Chl) and carotenoid contents varied among phyla, but not with the sampling location. Chl a and b were the major chlorophylls in Chlorophyta. Chl a and Chl c were the main chlorophylls in Ochrophyta, while Chl a was the dominant chlorophylls in Rhodophyta. β-Carotene and fucoxanthin were detected as major seaweed carotenoids. The former was present in all species in a variety of ranges, while the latter was mainly found in Ochrophyta and in small quantities in Rhodophyta, but not in Chlorophyta. The total lipids (TL) content and fatty acids composition were strongly affected by sampling location. The TL and n-3 PUFAs levels tended to be higher in temperate seaweeds compared with those in tropical seaweeds. The major n-3 PUFAs in different phyla, namely, eicosapentaenoic acid (EPA) and stearidonic acid (SDA) in Ochrophyta, α-linolenic acid (ALA) and SDA in Chlorophyta, and EPA in Rhodophyta, accumulated in temperate seaweeds. Chlorophylls, their derivatives, and carotenoids are known to have health benefits, such as antioxidant activities, while n-3 PUFAs are known to be essential nutrients that positively influence human nutrition and health. Therefore, seaweed lipids could be used as a source of ingredients with health benefits for functional foods and nutraceuticals.

“…Akibat buruk dari radikal bebas ini adalah mampu mempengaruhi membran dan inti sel sehingga mampu merusak dirinya sendiri. (Ito et al, 2018) Adapun sel yang sering diserang radikal bebas adalah sel lemak, sel protein dan sel asam nukleat. Salah satu mekanisme pertahanan tubuh terhadap serangan radikal bebas adalah zat antioksidan(Amarowicz, Pegg, Rahimi-Moghaddam, Barl, & Weil, 2004) Zat antioksidan banyak ditemukan di makanan yang mengandung vitamin A, vitamin C, vitamin E, selenium, beta karoten, lutein dan lignan.…”

ABSTRAKKandungan dalam alga meliputi polisakarida, mineral, protein, lemak, vitamin, polifenol dan senyawa bioaktif yang bisa memberikan manfaat terhadap sumber makanan, vitamin maupun pharmasi. Investigasi karakter Alga Coklat dan Alga Merah yang diperoleh dari perairan pulau pari kepulauan seribu wilayah Indonesia dilakukan dengan tujuan untuk mendapatkan zat yang mampu menjadi alternatif sumber anti oksidan . Metode yang digunakan dalam penelitian ini adalah ekstraksi maserasi dengan pelarut Phosfat Buffer Saline (PBS) sedangkan Uji kadar protein alga menggunakan metode Lowry dan uji aktivitas antioksidan menggunakan metode 1,1-Diphenyl-2-Pycrylhydrazy(DPPH). Hasil penelitian menunjukkan kadar protein yang tertinggi diperoleh pada sampel alga merah, sedangkan nilai kadar protein paling rendah terdapat pada alga cokelat . Nilai aktivitas antioksidan yang paling baik yaitu pada sampel yang berasal dari alga merah dengan nilai IC50 sebesar 3,5421 mg/ml.Kata Kunci: Alga, protein, antioksidan.ABSTRACTAn alga contains polysaccharides, minerals, proteins, fats, vitamins, polyphenols and bioactive compounds that can provide benefits for food, vitamin and pharmaceutical sources.
