enzymes

• enzymes


  biological catalyst that catalyze the chemical reactions necessary for growth, repair and maintenance of a living organism without which it could not survive
• iodine test


  chemical reaction that used to test for the presence of starch
• blue-black


  The combination of starch and iodine is intensely
• benedicts test

  when reducing sugars are heated in the presences of an alkali, they get converted into powerful reducing species known as enediols
• ptyalin

  enzyme called a-amylase that catalyzed the hydrolysis of starch
• water, mucin, and mineral salt


  components of saliva
• 99.49


  percentage of water in saliva
• saliva


  Aid in swallowing the food and contains enzyme that hydrolyzes starch to dextrins and maltose and eventually simple reducing sugar
• lower catalase activity


  Tissues which are not physiologically active have
• higher catalase activity


  Tissues which are physiologically active have
• Pepsin, trypsin, and ptyalin 


  are classified as hydrolases or hydrolytic enzymes
• Pepsin 


  acts on carbonyl side of the peptide bonds near aromatic amino acids
• brick red precipitate


  positive result for benedicts test
• benedicts test


  can be used to find out the amount of reducing sugar
• blue solution


  indicates no reducing sugar
• green or yellow precipitate


  indicates traces of reducing sugar
• orange red precipitate


  indicates moderate amount of reducing sugar
• brick red precipitate


  large amounts of reducing sugar
