Lactose content of breast milk per 100 ml is –
**Question:** Lactose content of breast milk per 100 ml is –
---
**Core Concept:** Lactose is a major carbohydrate component of human milk, primarily produced by the mammary gland cells. Human milk contains essential nutrients, including carbohydrates, proteins, lipids, vitamins, and minerals, which are crucial for the growth and development of the infant.
**Why the Correct Answer is Right:** Lactose is the primary carbohydrate found in human milk, making up approximately 3-8% of its composition. In this case, the correct answer represents the average lactose content per 100 ml of breast milk.
**Why Each Wrong Option is Incorrect:**
A. 15 g: This option is incorrect because lactose is not measured in grams but is expressed as a percentage of the total milk composition.
B. 10 g: This option is also incorrect as lactose is measured in percentage, not grams.
C. 6 g: This option is wrong because the actual lactose content in breast milk is typically around 3-8%, which is higher than the given amount.
**Clinical Pearl / High-Yield Fact:**
Human milk is a dynamic fluid that changes based on various factors, including the mother's diet, emotional state, and infant demand. It contains a well-balanced composition of macronutrients (carbohydrates, proteins, lipids), micronutrients (vitamins and minerals), and antibodies that confer protection against various infections.
**Correct Answer:** D. 3 g
Explanation: The correct answer represents the average lactose content in breast milk, expressed as a percentage (3-8%), which is approximately 3 grams per 100 ml. This information is crucial for understanding the nutritional composition of breast milk and its role in meeting the nutritional needs of the infant.
