Ethyl cellulose
CAS:Ethyl cellulose is similar in structure to methyl cellulose with ethyl replacing the methyl groups. It is approved for use in regulated markets such as food and pharmaceuticals. In pharmaceuticals it can mask the taste of bitter actives, enhance the strength and appearance of tablets and capsules, and enable controlled release formulations. In food products it functions as a binder, film former and flavour fixative.Pureza:Min. 95%Cor e Forma:White Yellow PowderCellulose, particle size 20μm
CAS:Cellulose with a particle size of 20μm is an industrial biomass material that has various applications. It is commonly used in the production of paper, textiles, and biofuels. Cellulose is a complex carbohydrate that provides structural support to plant cell walls. It can also be used as an excipient in pharmaceutical formulations, such as in the production of tablets.Pureza:Min. 95%Cor e Forma:PowderAmylopectin - from maize
CAS:<p>Amylopectin is composed of between 2,000 to 200,000 glucose residues linked α (1→4) with α (1→6) branching. The molecule is highly branched, every 24 to 30 glucose units, resulting in a soluble molecule with many terminal residues. Starch is made of about 70% amylopectin by weight, though it varies depending on the source (higher in medium-grain rice to 100% in glutinous rice, waxy potato starch, waxy corn, and lower in long-grain rice, amylomaize, and russet potatoes).</p>Cor e Forma:PowderGlycogen - from oyster for molecular biology
CAS:<p>Glycogen is a highly branched polysaccharide of glucose that serves as a form of energy storage in animals and fungi. It is the main storage form of glucose in the body. In humans, glycogen is made and stored primarily in liver and muscle cells and functions as the second most important energy storage molecule to fat which is held in adipose tissue. Glycogen is analogous to starch and has a structure similar to amylopectin, but is more extensively branched and compact than starch. It occurs as granules in the cytosol/cytoplasm in many cell types, and plays an important role in the glucose cycle.</p>Pureza:Min. 95%Fluorescein isothiocyanate-dextran - Average MW 70,000
CAS:<p>Anterograde and retrograde tracer in neurons; biologically inert</p>Pureza:Min. 95%Hydroxypropyl cellulose - Average MW 80,000
CAS:<p>In water, hydroxypropyl cellulose forms liquid crystals with many mesophases depending on concentration. These mesophases include isotropic, anisotropic, nematic and cholesteric, the latter resulting in many colors such as violet, green and red. Pharmaceutical applications include treatments for medical conditions such as dry eye syndrome (keratoconjunctivitis sicca), recurrent corneal erosions, decreased corneal sensitivity, exposure and neuroparalytic keratitis. It is also used as a binder in tablets. Hydroxypropylcellulose is also used as a thickener, a binder and emulsion stabiliser in foods with E number E463. HPC is used as a support matrix for DNA separations by capillary and microchip electrophoresis.</p>Pureza:Min. 95%D-Aminogalacturonic Acid Hydrochloride

CAS:<p>Ulvans are structural polysaccharides present in the cell walls of green algae such as Ulva armoricana, Ulva rotondata, Ulva rigida, Ulva lacterca and Ulva pertusa. They are highly sulphated and contain rhamnose 3-sulphate, xylose, xylose 2-sulphate, glucuronic acid and iduronic acid residues. Ulvan has several potentially valuable functionalities such as gel formation for agricultural and food applications and possible anticoagulant, antioxidant, antihyperlipidemic and antitumoral activities for pharmaceutical applications.<br>The image was kindly provided by Prof Mike Guiry from Cork who runs ‘The Seaweed Site’.</p>Pureza:Min. 95%Fluorescein isothiocyanate-carboxymethyl-dextran - Average MW 4,000

CAS:<p>Cellulose acetate phthalate (CAP) finds use in the formulation of pharmaceuticals, such as the enteric coating of tablets or capsules and for controlled release formulations, where it is often used with other coating agents such as ethyl cellulose. It contains about 50% acetate and 25% as the phthalate ester with the rest as free hydroxyl groups. Enteric coatings based on CAP are resistant to acidic gastric fluids, but easily soluble in mildly basic medium of the intestine. The pH-sensitive solubility of CAP is mainly determined (as are other properties of this mixed ester) by the degree of substitution and by the molar ratio (acetyl and phthaloyl groups).</p>Pureza:Min. 95%Hydroxypropyl cellulose - Average MW 100,000
