Chemical components of seaweeds—carbohydrates, proteins and low molecular weight nitrogenous compounds, minerals, lipids, vitamins, volatile compounds, and pigments—are reviewed in relation to potential food uses. The larvae are often washed out of the wrack by storm events The chemical composition of two seaweed flies (Coelopa frigida and Coelopa pilipes) reared in the laboratory The chemical composition of fresh hides and skins falls approximately within the following limits: •Water 60%-65% •Protein 25%-30% •Fats 5%-10% . Seaweed also contains minerals essential such as Ca, Mg, Se, chemical composition (F, Ca, Mg, Na, K, Fe, Mn, Zn, Cu, Ni, Co, Cr, Cd, and carbohydrate) of different marine seaweeds (red, green, and brown) from the Egyptian Mediterranean Sea coast. Certain seaweeds contain Protein content from These seaweeds contained high proportions of ash (from 20.46–51.56%). The results showed that green seaweeds supplied better calcium sources than the red and brown ones. Keywords: chemical composition, fatty acid, functional properties, mineral composition seaweed 1. In the present study, three common Egyptian seaweeds (Dictyota dichotomaTurbinaria decurrens, and . The nutritive values of seaweeds are briefly discussed. Moubayed*, Hadeel Jawad Al Houri, Manal M. Al Khulaifi, Dunia A. Al Farraj King Saud University, Sciences College, Microbiology Department, Girls Campus, P.O. The chemical composition of nutrients from seaweed was determined by the species and environmental conditions such as habitat, light, water temperature and salinity, may be caused differences in the nutritional composition of seaweed (Burtin, 2003, and Darcy-Vrillon 1993). This research is aimed to analyze the chemical and mineral composition of dried red seaweed Eucheuma spinosum from Nusa Penida, Sumenep, and Takalar. The proximate chemical composition, essential trace elements, heavy metals, minerals and ash of three indigenous seaweeds: brown (Padina pavonia), red (Pterocladia capellace) and green (Ulva lactuca) from Alexandria coast were investigated. Introduction Seaweed is a common term for marine macroalgae. seaweeds are a potential source of essential minerals which can be used to promote good health. The results of the analysis of … on the decaying seaweeds and the bacteria found on the seaweed surface (Cullen et al., 1987; Dobson, 1974). Antimicrobial, antioxidant properties and chemical composition of seaweeds collected from Saudi Arabia (Red Sea and Arabian Gulf) Nadine M.S. Seaweeds are one of the commercially important marine living and renewable resources. 2 STRUCTURE OF HIDES AND SKINS Most hides and skins consist of three parts, such as (i) Epidermis, (ii) Corium or true skin and Summary This chapter contains sections titled: Introduction Various components of seaweeds Conclusion References Chemical Composition of Seaweeds - Handbook of Marine Macroalgae - Wiley Online Library Box 22452, Riyadh 11495, Saudi Arabia Laurencia obtusa) were collected from the Red Sea coast, Suez, Egypt. industry, which increases the importance of evaluating their chemical composition. Analysis of the chemical composition was moisture, ash, protein, fat, fiber, and carbohydrate contents. The mineral element was macrominerals (Ca, Cl, K Mg, and Na) and micro minerals (Zn and Cu). The chemical profile of the three seaweeds was studied beside the antioxidant They are classified based on their chemical and nutrition composition as phaeophyta (brown algae), rhodophyta (red algae) and chlorophyta (green algae) (Dawczynski et al., 2007). Variability in chemical components and growth of algae may be inter specific, intra-annual or inter-annual. The objectives of this study were to identify the invasive Sargassum on the coast of Ghana and to determine the chemical composition in order to promote its use as food or fertilizer to improve the livelihood of the coastal communities.
