Approximately how much protein is present in mature human breast milk (per 100 mL)?

• A. About 1.0 g per 100 mL
• B. About 0.1 g per 100 mL
• C. About 10 g per 100 mL
• D. About 5.0 g per 100 mL

Answer: (A)

Verified step by step guidance

1. Understand that mature human breast milk contains various macronutrients, including proteins, fats, and carbohydrates, each present in characteristic concentrations.
2. Recall or refer to standard biochemical data on the composition of mature human breast milk, which typically lists protein content in grams per 100 mL.
3. Recognize that the protein concentration in mature human breast milk is relatively low compared to other macronutrients, generally around 1 gram per 100 mL.
4. Compare the given options with the known typical protein concentration to identify the closest value.
5. Conclude that the approximate protein content in mature human breast milk is about 1.0 g per 100 mL based on standard biochemical references.
