Fats serve as the best storage of spare energy becuase

biology food for health fats fats and their test different nutrients in food

  1. Fats yield double amount of energy yielded by glucose on oxidative breakdown

  2. Fats can be stored in an almost pure unhydrated form

  3. Fats accomodate in lesser space

  4. All the above

Show answer
Correct Option: A
Explanation:

Fat is an essential part of our diet and is important for good health.

fat is the major storage form of energy in the body. These are found in plant foods and fish. Fats help in the absorption of fat-soluble vitamins A, D, E, and K. 

So, the correct option is ‘Fats yield the double amount of energy yielded by glucose on oxidative breakdown’.

An example for essential fatty acids

biology food for health fats fats and their test different nutrients in food

  1. Glutamic acid

  2. Aspartic acid

  3. Linoleic acid

  4. Tartaric acid

Show answer
Correct Option: C
Explanation:

Essential fatty acids, or EFAs, are fatty acids that humans and other animals must ingest because the body requires them for good health but cannot synthesize them. Two essential fatty acids, linolenic and linoleic acid, cannot be synthesized in the body and must be obtained from food. These basic fats, found in plant foods, are used to build specialized fats called omega-3 and omega-6 fatty acids.

Each fat molecule is formed from 

biology food for health fats fats and their test different nutrients in food

  1. One glycerol molecule and one fatty acid molecule

  2. One glycerol molecule and three fatty acid molecules

  3. Three glycerol molecules and one fatty acid molecule

  4. Three glycerol molecules and three fatty acid molecules

Show answer
Correct Option: B
Explanation:

Fatty acids are long, straight chain carboxylic acids. A fat molecule is formed when three fatty acids molecules combine with one glycerol molecule to yield a triglyceride (another name for fat) along with three water molecules. Fats are not easily digested and are transported and stored as triglycerides.

So, the correct option is 'One glycerol molecule and three fatty acid molecules'.
