Question

1. explain what unit is used to measure protein?

Explanation:

Protein can be measured using different units depending on the context. The most common unit for quantifying protein mass in nutrition and lab settings is grams (g) for larger amounts, and milligrams (mg) or micrograms (μg) for smaller, precise measurements. For biological assays that measure protein concentration, units like milligrams per milliliter ($\text{mg/mL}$) or micrograms per milliliter ($\text{μg/mL}$) are used. Additionally, the Dalton (Da) or kilodalton (kDa) is used to measure the molecular weight of individual protein molecules.

Answer:

Common units for measuring protein include:

• Grams (g), milligrams (mg), micrograms (μg) for total mass (used in nutrition, bulk samples)
• Milligrams per milliliter ($\text{mg/mL}$), micrograms per milliliter ($\text{μg/mL}$) for concentration (lab assays)
• Dalton (Da) / kilodalton (kDa) for molecular weight of protein molecules
