Fucus vesiculosus

Optimization Of Phlorotannins Extraction From Fucus vesiculosus

Phlorotannins are phenolic compounds consisting of dehydro-oligomers or dehydro-polymers formed through the C–C and/or C–O–C oxidative coupling of phloroglucinol (1,3,5-trihydroxybenzene); monomeric units that are to occur particularly on brown macroalgae. Indeed, species such as Eisenia bicycles, Ishige okamurae, Sargassum thunbergii, Sargassum fusiforme, Undaria pinnatifida, and Ascophyllum nodosum. The Ecklonia and Fucus As well as algae belonging to the genera Cystophora,…

Antimicrobial Peptide Holothuroidin 2 From Mediterranean Sea Cucumber

There is an urgent need for novel classes of antibiotics able to escape the most common resistance mechanisms of pathogens. Antimicrobial peptides (AMPs) are currently considered ideal candidates; for the development of new classes of antimicrobials effective against resistant pathogens. Their mechanism of action, which involves the perturbation of the membrane structure rather than the…

Hydroxyacid Mixtures to Sea Urchin Paracentrotus lividus Embryos

Oxylipins are oxygenated fatty acids derivatives distributed in a wide range of organisms; including plants and algae, where they are involves in the regulation of several physiological processes. In diatoms, these molecules are produced through an enzymatic cascade activated after cell breakage. In this process, specific lipoxygenases mediate the oxygenation of polyunsaturated fatty acids (PUFAs);…

Conopeptides

Computational Studies On The Conopeptides

Marine cone snails from the family Conidae capture their prey and defend themselves using venoms containing short proteins called conopeptides. So the majority of these toxins range in sequence length from 10 to 45 amino acids; with a median size of 26 residues. Every species from the family Conidae can produce in excess of a thousand…

Encoded By The Genome Of The Scleractinian Coral Stylophora Pistillata

Coral reef architecture comes from the deposition of massive calcium carbonate skeletons secreted by scleractinian corals; or hard corals. These corals represent the habitat for a vast diversity of organisms. They live in intimate symbiosis with unicellular dinoflagellate symbionts; commonly called zooxanthellae; which are in the coral tissues. The enzymes carbonic anhydrases play major roles…

Oxidation Stability Of Micro Encapsulated Omega-3 Concentrates

Enzymatically concentrated anchovy oil  is known to be much less stable than concentrated anchovy oil. However, we previously showed that concentrate surprisingly forms more stable micro capsules, when produced by complex coacervation, than does concentrate anchovy oil. Here we investigate the mechanism of this unexpected stability. Investigate whether We also investigate whether or not incorporation…

The Osteogenic Potential Of Brown Seaweed Extracts

Marine drugs hold significantly more promise than their terrestrial counterparts, which could help to solve the current shortfall in treatments for osteoporosis and other bone related diseases. Fucoxanthin is the main carotenoid find in brown seaweed, and has many perceive health benefits, including potential bone therapeutic properties. Photogenic potential This study assessed the osteogenic potential…

Omega-3 Fatty Acids Help Prevent Miscarriages

Compounds found in fish oil prevent pregnancy complications, including preterm birth, neonatal death, and stillbirth, in mice when the complications are caused by a common oral bacteria, according to research published today in the journal JCI Insight. The study, by scientists at Columbia University’s College of Dental Medicine and Vagelos College of Physicians & Surgeons, suggests…

Properties Of Type I Collagen From The Skin Of Nile Tilapia

The aim of this study is to investigate the physicochemical properties, bio safety, and bio compatibility of the collagen extract from the skin of Nile tilapia, and evaluate its use as a potential material for biomedical applications. because Two extraction methods were used to obtain acid soluble collagen (ASC) and pepsin-soluble collagen (PSC) from tilapia…

Mom's Prenatal Fish Oil Help Kids' Blood Pressure Later

Obese young children may have less risk for high blood pressure if their mother took the omega-3 fatty acid DHA—found in fish oil during pregnancy, new research suggests. The findings could be important since rising numbers of American children are obese and experiencing hikes in blood pressure. Blood pressure tracks That could have long-term consequences for their health, said study…

Marine Sponges

Leucettazoles As Cryptic Macro cyclic Alkaloid Dimers From a Marine Sponge

Marine sponges are a remarkable source of structurally diverse natural products. For example, over several decades, our investigation of southern Australian marine sponges revealed a wealth of natural product classes, many unique to marine sponges. These include the terphenyls luffarins and trunculins, the alkaloids trachycladindoles and dragmacidins, the polyketides franklinolides and amphilactams; the lipids heterofibrins and thiocyanate; and…

Collagen Of Extracellular Matrix From Marine Invertebrates

The extraction and purification of collagen are of great interest due to its biological function and medicinal applications. Although marine invertebrates are abundant in the animal kingdom, our knowledge of their extracellular matrix (ECM), which mainly contains collagen, is lacking. The functions of collagen isolated from marine invertebrates remain an untouched source of the proteinaceous…
