1. Enzymes: Enzymes are proteins that catalyze biochemical reactions in the body. They act as biological catalysts, speeding up chemical reactions that are necessary for various cellular processes such as metabolism, digestion, and DNA replication.
2. Structural proteins: Structural proteins provide support and shape to cells and tissues. Examples include collagen, which provides strength and elasticity to connective tissues, and keratin, which forms the structure of hair, nails, and skin.
3. Transport proteins: Transport proteins are responsible for moving molecules and ions across cell membranes and throughout the body. Examples include hemoglobin, which transports oxygen in the blood, and ion channels, which regulate the flow of ions in and out of cells.
4. Hormones: Hormones are signaling proteins that regulate various physiological processes in the body. They act as chemical messengers, coordinating activities such as growth, metabolism, and reproduction. Examples include insulin, which regulates blood sugar levels, and adrenaline, which triggers the body's fight or flight response.
5. Antibodies: Antibodies are proteins produced by the immune system in response to foreign substances such as pathogens or toxins. They help to identify and neutralize these invaders, protecting the body from infection and disease.
6. Motor proteins: Motor proteins are responsible for generating movement within cells and tissues. They play a key role in processes such as muscle contraction, cell division, and intracellular transport. Examples include myosin, which powers muscle contraction, and kinesin, which transports cellular cargo along microtubules.
