Question

What type of chemical reaction is involved in the digestion of fats? What products are formed? The average energy yield per gram of carbohydrate and of fat is a. 4 kcal each b. 9 kcal each c. 4 kcal and 9 kcal, respectively d. 9 kcal and 4 kcal, respectively How do animal fats differ from vegetable oils? What is a trans fat? How are trans fats made? What is an adequate protein? List some foods that contain adequate proteins. What is the limiting reactant in any protein synthesis? Which essential amino acids are likely to be lacking in corn? In beans? What is kwashiorkor? What age group in developed countries suffers a similar condition? Ezekiel 4:9 describes a brad made from "wheat, and barely, and beans, and lentils, and millet, and spelt ...." Would the bread supply complete protein? How do dietary proteins differ from dietary carbohydrates and fats in elemental composition?

Explanation / Answer

17. a Glycosidic linkage

18. Blood sugar - Glucose C6H12O6

Table sugar - Sucrose C12H22O11

Fruit sugar - Fructose -C6H12O6

19. Chemical reaction involved in digestion of starch is

Starch is broken down to smaller units called maltose by amylase enzyme

20 . The sugar formed when starch is digested is Maltose and then it is broken down to glucose

21. Lipases break bown the lipids into fatty acids and glycerides

22. Average energy yield per gram of carbohydrate is 4 kilocalories

Average yield per gram of fat is 9 kilo calories

23. Difference between animal fat and vegetable oil is

Vegetable oil is composed mostly of polyunsaturated fats which are missing more than 1 pair of hydrogens in its structure

Animal fats is composed mostly of monounsaturated fatswhich are missing only a single pair of hydrogens and saturated fats

24. Transfat is unsaturated fatty acid occurs in nature in small quantities but can be produced industrially from vegetable fat.

Transfat is made from by addition of hydrogen to vegetable oil in food processing

25.Protein is a nutrient needed by the human body for growth and maintenance.Protein can be found in all cells of the body and is the major structural component of all cells in the body, especially muscle.

Black beans, Brocoli, peas, peanut butter, spinach, tofu, quinoa, wheat bread are some sources of proteins

26. Limiting reagent in any protein synthesis is an essential amino acids.

27. Corn - Lysine and threonine             Beans - Methionine and tryptophane

28.Kwashiorkor is a form of severe protein–energy malnutrition characterized by edema, irritabilityand an enlarged liver with fatty infiltrates. Age group of 1-5 years.

29. Bread has less amount of threonine essential amino acid.

30. The proteins are complex molecules and they need more time to break them down in decomposition
