10. Pharmaceutical ingredients are susceptible to microbial attack. Which ONE of the following statements about contamination of a medicine is CORRECT? O Anionic surfactants are generally stable but the alkyl and alkylbenezene sulphonates are readily metabolised. O Humectants, such as sorbitol and glycerol, are readily metabolised when present in a medicine at high concentrations. O Fats and oils are usually attacked when dispersed in non-aqueous formulations. O Sweetening, flavourings and colouring agents are ready substrates for bacteria but in low concentrations are resistant to degradation. O Organic polymers used as thickening agents are subject to microbial polymerisation.

Essential nutrients
These are the organic compounds present in the food that provide nourishment essential for the development and growth of our body. Nutrients not only provide us with the required energy to carry out various biological processes but are also the building blocks for repair and growth in our bodies.
Vitamins
The vitamins are organic molecules required in low concentration for the proper functioning of the body. They cannot be generated in the organism and are taken into the body through the diet. The lack of proper vitamins results in diverse deficiency disorders. They are thus called essential nutrients. The important vitamins are vitamin A, vitamin B complex, vitamin C, vitamin D, vitamin K, and vitamin E.
