Matching Vitamins with Their Alternative Names
Vitamins are essential nutrients that our bodies need to function properly. Each vitamin often has one or more alternative names, which are usually their chemical names. This question asks us to match common vitamins with these alternative names.
Let's look at each vitamin listed in Column A and find its corresponding alternative name in Column B.
- \text{Vitamin A}: This vitamin is crucial for vision, immune function, and cell growth. Its most common alternative name is Retinol. So, \text{Vitamin A} matches with Retinol.
- \text{Vitamin B}_{12}: This is a complex vitamin essential for nerve function and the formation of DNA and red blood cells. It contains the element cobalt, which is reflected in its alternative name, Cobalamin. So, \text{Vitamin B}_{12} matches with Cobalamin.
- \text{Vitamin C}: Known for its role in immune support and collagen synthesis, \text{Vitamin C} is a powerful antioxidant. Its chemical name is Ascorbic acid. So, \text{Vitamin C} matches with Ascorbic acid.
- \text{Vitamin D}: Important for calcium absorption and bone health, \text{Vitamin D} can be synthesized in the skin upon exposure to sunlight. Different forms exist, like Vitamin D2 (Ergocalciferol) and Vitamin D3 (Cholecalciferol). Ergocalciferol is listed as an alternative name for \text{Vitamin D} in general or specifically Vitamin D2. So, \text{Vitamin D} matches with Ergocalciferol.
Based on these matches, we can form the correct pairs:
\text{i. Vitamin A} corresponds to \text{b. Retinol}
\text{ii. Vitamin B}_{12} corresponds to \text{c. Cobalamin}
\text{iii. Vitamin C} corresponds to \text{a. Ascorbic acid}
\text{iv. Vitamin D} corresponds to \text{d. Ergocalciferol}
Let's summarize the matching pairs in a table:
| Column A (Vitamin) | Column B (Alternative Name) | Match |
|---|---|---|
| i. \text{Vitamin A} | b. Retinol | i - b |
| ii. \text{Vitamin B}_{12} | c. Cobalamin | ii - c |
| iii. \text{Vitamin C} | a. Ascorbic acid | iii - a |
| iv. \text{Vitamin D} | d. Ergocalciferol | iv - d |
The correct combination of matches is i - b, ii - c, iii - a, iv - d.
Revision Table: Vitamin Names
It's helpful to review and remember the common names for these important vitamins.
| Vitamin | Alternative/Chemical Name | Key Function (Brief) |
|---|---|---|
| \text{Vitamin A} | Retinol | Vision, immune function |
| \text{Vitamin B}_{12} | Cobalamin | Nerve function, DNA synthesis |
| \text{Vitamin C} | Ascorbic acid | Antioxidant, collagen synthesis |
| \text{Vitamin D} | Ergocalciferol (D2) / Cholecalciferol (D3) | Calcium absorption, bone health |
Additional Information on Vitamins
Vitamins are classified into two main categories: fat-soluble and water-soluble.
- Fat-Soluble Vitamins: These include Vitamins A, D, E, and K. They are absorbed with dietary fats and stored in the body's fatty tissues and liver. Because they can be stored, they can accumulate to toxic levels if consumed in excessive amounts.
- Water-Soluble Vitamins: These include the B vitamins (\text{B}_1, \text{B}_2, \text{B}_3, \text{B}_5, \text{B}_6, \text{B}_7, \text{B}_9, \text{B}_{12}) and \text{Vitamin C}. They are not stored in the body to a significant extent and are excreted in urine. This means they need to be consumed more regularly, but toxicity is rare.
Understanding the alternative names of vitamins is important for reading food labels, supplements, and scientific literature.
