Question

Consider the following statements about Amino acids and vitamins

1. The key elements of an amino acid are carbon (C), hydrogen (H), oxygen (O), and Sulphur (S).

2. A vitamin is an organic molecule that is an essential macronutrient.

Select the correct answer using the code given below:
1. Only 1
2. Only 2
3. Both 1 and 2
4. Neither 1 nor 2

Answer 1

Correct Answer - Option 4 : Neither 1 nor 2

• Amino acids are organic compounds that contain amino and carboxyl functional groups, along with a side chain specific to each amino acid.
• The key elements of an amino acid are carbon (C), hydrogen (H), oxygen (O), and nitrogen (N), although other elements are found in the side chains of certain amino acids.
• In the form of proteins, amino acid residues form the second-largest component (water is the largest) of human muscles and other tissues.
• Beyond their role as residues in proteins, amino acids participate in a number of processes such as neurotransmitter transport and biosynthesis.
• A vitamin is an organic molecule that is an essential micronutrient which an organism needs in small quantities for the proper functioning of its metabolism.
• Essential nutrients cannot be synthesized in the organism, either at all or not in sufficient quantities, and therefore must be obtained through the diet.
• Vitamin C can be synthesized by some species but not by others; it is not a vitamin in the first instance but is in the second.
• Most vitamins are not single molecules, but groups of related molecules called vitamers.
