undefined The human body uses proteins for a variety of purposes, such as: 1. **Building and Repairing Tissues**: proteins are necessary for the development, maintenance, and repair of bodily tissues, including muscles, skin, and organs; 2. **Enzymes**: proteins function as biological catalysts that quicken chemical reactions in the body, such as food digestion; 3. **Hormones**: some proteins act as hormones, regulating various physiological processes like metabolism, growth, and development; 4. **Transportation**: proteins move substances throughout the body, including oxygen (as hemoglobin) and lipids (as lipoproteins) 5. **Immune Function**: proteins serve as antibodies, which are proteins that are vital for the immune system's operation and aid in the body's defense against infections.
