What are proteins?
- Proteins are chemical compounds that catalyze reactions. Protein is an incredibly complex chemical found in all living things.
- Proteins are high in nutritional value and play an important role in many of the chemical reactions necessary for life.
- Chemists discovered the use of proteins in the early nineteenth century. Because proteins are species-specific, the proteins of one species differ from those of another.
- They are also organ-specific; for example, muscle proteins differ from brain and liver proteins within the same organism.
- A protein molecule is much larger than a sugar or salt molecule because it is composed of several amino acids that are linked together to form long chains, similar to beads on a string.
- Proteins naturally contain about 20 different amino acids.
