Which of the following organic acid is used as a source of calcium for infants , cows and lactating mothers?

Options

A. Gluconic acid
B. Lactic acid
C. Citric acid
D. Acetic acid

Answer

To solve the question regarding which organic acid is used as a source of calcium for infants, cows, and lactating mothers, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Organic Acids**: The question presents four options: gluconic acid, lactic acid, citric acid, and acetic acid. We need to evaluate each of these acids to determine which one is a source of calcium.

2. **Research Each Acid**:
- **Gluconic Acid**: This organic acid is known to be a good source of calcium. It can be derived from the fermentation process involving certain fungi, such as Aspergillus niger and Penicillium.
- **Lactic Acid**: While lactic acid is important in various biological processes, it is not primarily known for being a source of calcium.
- **Citric Acid**: Citric acid is commonly found in citrus fruits and is involved in the citric acid cycle, but it is not primarily recognized as a source of calcium.
- **Acetic Acid**: Acetic acid is the main component of vinegar and does not serve as a significant source of calcium.

3. **Conclusion**: Based on the information gathered, gluconic acid is identified as the organic acid that serves as a source of calcium for infants, cows, and lactating mothers.

4. **Final Answer**: The correct answer is **Gluconic Acid**.
