The Biuret Test (for Protein) Proteins are large molecules To test for presence of protein in a food sample we add a chemical called biuret solution. Like the reducing sugar test, chop up the food and dissolve in water to a height of 2cm. Now add an equal volume of buiret solution If...
Figure2illustrates the pH change during the biofilm formation. For the pre-treatment strategy, the pH was measured before adding sucrose and 6 h after sucrose addition, confirming pH fluctuations in the cycles. Prior to exposure to sucrose cycling, the pH of the media in the cranberry-pre-trea...
A method to demonstrate performance of a palladium hydrogen (PdH) reference electrode in comparison to a silver/silver chloride reference electrode (Ag/AgCl) for two carbohydrate applications: honey sugars and glycoprotein monosaccharides. Application note ...
Ginger is a digestive stimulant that promotes gastric flow and contains enzymes that aid in proper digestion. It has been known to reduce digestive discomfort, nausea, pain, and inflammation. A 2018 systematic review has found that ginger is beneficial for reducing risks and symptoms of gastrointest...
for electrochemical sensing involves invasive procedures such as finger-pricking or venipuncture, which can cause discomfort for users of POC devices. Accordingly, recent research has focused on the detection of biomarkers using alternative biofluids that can be sampled noninvasively. For example, ...
lysine side chain of one gelatin molecule to a similar amine group on another molecule. This reaction generally is catalyzed by trace amounts of reactive aldehydes. Formaldehyde, glutaraldehyde, glyoxal, and reducing sugars are the most common catalysts. The covalent bonding ...
