Enzymes

  • Amylase, clarase

    Amylase (clarase) is supplied as a light coloured powder. It is a form of alpha-amylase that acts on starch (amylose and amylopectin) and breaks it down to simple sugars such as maltose and dextrins. Many organisms, including humans, use amylase to...

  • Amylase, diastase

    Amylase (diastase) is supplied as a cream to white powder.  It is a form of alpha-amylase that acts on starch (amylose and amylopectin) and breaks it down to simple sugars such as maltose and dextrins.  Many organisms, including humans, use...

  • Catalase

    Catalase is a high activity enzyme that facilitates the decomposition of hydrogen peroxide to harmless oxygen and water.  This is a protective function to prevent cell damage that could be caused by hydrogen peroxide, a powerful oxidizing agent...

  • Cellulase

    The term "cellulase" describes a class of enzymes that break cellulose down into oligosaccharides and ultimately to simple sugars such as glucose.  Bacteria in the digestive tract of herbivores use cellulase to digest cellulose that the animals have...

  • Invertase

    Invertase is a type of sucrase. It is known to occur in plants and some micro-organisms, and in school science experiments it can be used as a substitute for the human digestive form of sucrase that is found in the small intestine

  • Lactase

    Lactase is a digestive enzyme that hydrolyses lactose, a sugar found in milk, to glucose and galactose.  In humans, lactase is present in infants, but the gene that regulates its expression can be turned off after weaning, leading to lactose...

  • Lipase

    Lipase is a digestive enzyme that hydrolyses the ester bonds of triglycerides to release fatty acids and glycerol (propylene glycol).  As the reaction proceeds, the pH decreases as a result of the rising concentration of carboxylic acids.  This...

  • Pancreatin

    Pancreatin is a mixture of digestive enzymes containing amylase (breaks down starch), lipase (breaks down fats), and protease (breaks down proteins).  To observe the multifunctionality of pancreatin, use it to treat each of these different...

  • Pectinase

    Pectin is a natural polysaccharide that forms a colloidal gel in plants to confer rigidity and to help regulate water transport between cells.  It is used as an additive in cooking to "set" jams.  Pectinase is an enzyme that breaks pectin down...

  • Pepsin

    Pepsin is a digestive protein found in the highly acidic environment of the stomach. It acts on proteins to break them down to their constituent amino acids. Pepsin is an ideal enzyme for studying the effect of pH because its functionality is reduced in...

  • Protease

    Proteases are enzymes that act on proteins to break them down into smaller units, ultimately to their constituent amino acids.  An important class of protease is involved in digestion and acts to release amino acids from dietary protein for use in...

  • Rennet

    Rennet is a mixture of enzymes found in the stomachs of certain infant mammals.  It has the specialized function of assisting in the digestion of milk from the mother.  The main constituent of rennet is rennin (also called chymosin) which...

  • Trypsin

    Trypsin is supplied as powder that, in solution, acts to break down protein into its constituent amino acids. The source is mammalian (porcine). Although trypsin will act on many different forms of protein, we have found its action on casein in low-fat...

  • Urease, 10g

    There are many different forms of urease in nature, but all have the common function of catalysing the breakdown of urea into carbon dioxide and ammonia.  In plants, this is usually a means to access the nitrogen in urea, but in many bacteria, it is...
