Algae have many types of life cycles, and they range in size from microscopic Micromonas species to giant kelps that reach 60 metres (200 feet) in length. European Journal of Mass Spectrometry. A class of compounds attracting increasing attention are the phlorotannins found in brown algae, which have extraordinary though inconsistent antioxidant properties (see in Wang et al. (2011) found that extracts of Ascophyllum and Alaria inhibited Caco-2 colon cancer cell proliferation, -amylase activity and, to a lesser extent, -glucosidase activity, with mass spectrometric evidence indicating that the active principal(s) were phlorotannins.

(2016) found that Fe (and other metal) contents varied, in some cases substantially, among macroalgal species collected at the same sites and time, presumably linked to differences in metabolic requirements. Table 10.3 shows the composition of various algae looking at the percentages of protein, carbohydrates, lipids, and nucleic acid.

However, the rate of clearance of DMA and other metabolites of an arsenosugar that was experimentally ingested appears to vary in different individuals; for example, although 4-day urinary excretion removed 85 % of the As represented in an ingested arsenosugar in four individuals, two other individuals excreted only 415 %. Effect of dietary beta-sitosterol on fecal bacterial and colonic biotransformation enzymes in 1,2-dimethylhydrazine-induced colon carcinogenesis. Experiments at all levels are important but it is particularly important to move beyond tests of toxicity using in vitro cell cultures in order to understand whether there is any risk of consuming any sea vegetable. First is the variation of nutritional and functional composition of algae across species, seasons, and different coastal environments. There are some compositions about algae oil which are as follows:- Fixed oils are used in algae oils because they are made up of vegetables, seeds, and Triglyceride is made up of three fatty acids nod glycerol.
