They are in fact mainly made up of long chains of sugars, called polysaccharides, which play a role similar to that of cellulose in plants and trees. Oligosaccharides are fragments of polysaccharides, smaller molecules often with bioactive properties of interest to a wide range of industries: cosmetics, pharmaceuticals, biomedicine and so on.<br \/>\nAmong these polysaccharides, alginates, derived from the brown algae that inhabit the coastal ecosystems of temperate and polar regions, are used as thickeners, gelling agents, emulsifiers and stabilizers, to encapsulate medicines, in laundry detergents and to make dental impressions. Brown seaweed&#8217;s polysaccharides also include sulfated fucans, whose oligosaccharides have been shown to have antioxidant, anti-infectious, healing and immune-boosting properties. But unlike alginates, these molecules of interest are not extracted on a large scale, and there are no specific enzymes commercially available to produce fucan oligosaccharides. This limits their use by industry, and that&#8217;s where <a href=\"https:\/\/www.aberactives.com\/en\/founders\/\"><strong>Gurvan Michel<\/strong><\/a> comes in.[\/vc_column_text]<div class=\"gem-textbox \"  ><div class=\"gem-textbox-inner\" style=\"\"><div class=\"gem-textbox-content\" style=\"background-color: #a3e7f0;background-position: center top;\"><div class=\"gem-alert-box\"><div class=\"gem-alert-inner\"><div class=\"gem-alert-box-picture\"><div class=\"gem-icon gem-icon-pack-material gem-icon-size-small  gem-icon-shape-square \"  style=\"border-color: #16b1a6;opacity: 1;\"><div class=\"gem-icon-inner\" style=\"background-color: #16b1a6;\"><span class=\"gem-icon-half-1\" style=\"color: #ffffff;\"><span class=\"back-angle\">&#xf3ce;<\/span><\/span><span class=\"gem-icon-half-2\" style=\"color: #ffffff;\"><span class=\"back-angle\">&#xf3ce;<\/span><\/span><\/div><\/div><\/div><div class=\"gem-alert-box-content\"><\/div><div class=\"gem-alert-box-buttons\"><div class=\"gem-button-container gem-button-position-center thegem-button-69eaab71afa805281    \"  ><a class=\"gem-button gem-button-size-small gem-button-style-flat gem-button-text-weight-normal\" data-ll-effect=\"drop-right-without-wrap\" style=\"border-radius: 3px;\" onmouseleave=\"\" onmouseenter=\"\" href=\"https:\/\/lejournal.cnrs.fr\/nos-blogs\/focus-sciences\/des-enzymes-pour-extraire-les-principes-actifs-des-algues-brunes\" target=\"_blank\">Read the full article on the CNRS &quot;Focus Sciences&quot; website<\/a><\/div> <\/div><\/div><\/div><\/div><\/div><\/div>[\/vc_column][\/vc_row]<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>[vc_row][vc_column][vc_column_text css=&#8221;&#8221;] Algae contain fascinating molecules, but in sugar chains that are difficult to break.
