Which of the following groups of organic compounds represent the proteins present in human blood?

Options

A. Pepsin, trypsin and chymotrypsin
B. Albumins, globulins and prothrombin
C. Valine, glycine and alanine
D. Glucose, fructose and galactose

Answer

To answer the question regarding which group of organic compounds represents the proteins present in human blood, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Blood Composition**: Human blood consists of two main components: plasma and formed elements. Plasma is the liquid part of blood, while formed elements include red blood cells (RBCs), white blood cells (WBCs), and platelets.

2. **Identifying Plasma Proteins**: Within the plasma, there are various proteins that play crucial roles in bodily functions. The main proteins found in blood plasma include:
- **Albumin**: Helps maintain osmotic pressure and transport substances.
- **Globulins**: Involved in immune responses and transport.
- **Fibrinogen**: Essential for blood clotting.

3. **Analyzing the Options**: We need to evaluate the provided options to identify which one contains the proteins found in human blood.
- **Option 1**: Papsin, Tripsin, and Chymotripsin are digestive enzymes that break down proteins but are not blood proteins.
- **Option 2**: Albumins, Globulins, and Prothrombin are all proteins found in human blood plasma.

4. **Conclusion**: Based on the analysis, the correct answer is **Option 2**: Albumins, Globulins, and Prothrombin, as these are the proteins present in human blood.
