    Study Notes

    Chymopapain and Its Uses

    • Chymopapain is utilized for treating herniated lumbar intervertebral discs via injection into the nucleus pulposus.
    • It hydrolyzes noncollagenous polypeptides, aiding in the structural integrity of chondromucoprotein.
    • Reduces lower back pain by diminishing osmotic activity, leading to decreased fluid absorption and lower intradiscal pressure.

    Proteolytic Enzymes Overview

    • Proteolytic enzymes facilitate the digestion and breakdown of proteins into amino acids.

    Specific Proteolytic Enzymes

    • Trypsin:

      • Found in the small intestine, aids digestion.
      • Commercially derived from livestock pancreas; also present in fungi and bacteria.
      • Used for wound debridement.

    • Sutilains:

      • Derived from Bacillus subtilis, used for wound debridement by digesting soft necrotic tissue.

    • Rennin:

      • Coagulating enzyme found in animal stomachs.
      • Curdles milk by converting caseinogen to insoluble casein; important in cheesemaking.

    • Erepsin:

      • Present in intestinal juice; converts proteoses and peptones into amino acids.

    • Streptokinase:

      • Produced by group C beta-hemolytic streptococci.
      • Converts plasminogen to plasmin, aiding in clot degradation.
      • Utilized in treating pulmonary embolism, deep vein thrombosis, and coronary artery thrombosis.

    • Urokinase:

      • Employed for treating blood clots within the cardiovascular system, excluding coronary and cerebral thrombosis.

    Oxidizing Enzymes

    • Catalyze oxidation reactions, essential for ATP production.

    • Peroxidase:

      • Common in plants, responsible for oxidative reactions causing bruised fruits' discoloration; breaks down hydrogen peroxide.

    • Thrombin:

      • Known as coagulation factor II; plays a key role in hemostasis and blood coagulation by converting fibrinogen to fibrin.

    Carbohydrase/Amyloytic Enzymes

    • Enzymes that transform carbohydrates into simple sugars.

    • Amylase:

      • Found in salivary glands, aids in the digestion of pre-cooked foods.

    • Invertase:

      • Found in yeast and intestinal juice; hydrolyzes sucrose into glucose and fructose.

    • Zymase:

      • Enzyme complex that catalyzes glycolysis; converts glucose into ethanol and carbon dioxide in fermentation.

    • Cellulase:

      • Works on coffee concentrate preparation and increases enzyme efficiency in food production.

    Esterases

    • Enzymes catalyzing the hydrolysis of ester groups, releasing esterified acids.

    • Lipase:

      • Breaks down fats into glycerin and fatty acids, contributes to cheese flavor production.

    • Pectase:

      • Involved in ripening fruits by transforming pectin into a soluble form.

    Additional Enzymes

    • Collagenase:

      • Breaks down collagen in animal tissues; used to treat severe burns and skin ulcers.

    • L-Asparaginase:

      • Treats acute lymphoblastic leukemia; also used in food production to reduce acrylamide.

    • Lipoxygenase:

      • Used in food production to whiten bread.

    Enzyme Applications

    • Medicine:

      • Enzymes aid in analytical tests for glucose levels in diabetics and diagnose diseases via enzyme leakage into the bloodstream.
      • Used therapeutically to supplement enzyme deficiencies, clear wounds, and assist in drug manufacture.

    • Industrial Uses:

      • Enzymes like rennin, cellulase, and amylase enhance food processing and improve product quality.
      • Utilized in detergents to break down stains, and in biofuel production to convert cellulose to glucose.
