Protein: Why Your Body Needs It?


Proteins are complex, large molecules that play various significant roles in the human body. They do a big part of the work in the cells. Proteins are the need for the functioning, structure, and regulation of the body organs and tissues of the human body. Proteins are the form of hundreds and thousands of amino acids. While amino acids are the smaller units that attach to the other in long chains. There are 20 various kinds of amino acids that combine to form a protein. The amino acid sequence examines each protein’s different 3-dimensional structure and its unique function.

Amino acids are encoded by the combinations of three building blocks of DNA (nucleotides), find by the number of genes. Any number of organic, complex macromolecules that consist of hydrogen, nitrogen, carbon, oxygen, and mostly sulfur consist of each or more amino acids chains. A protein is the essential substance of all living cells and contains many compounds like hormones, antibodies, and enzymes that are significant for an organism for proper functioning. They are necessary for the diet of animals for the repair of tissues, growth, and proper functioning. (1)

We can get protein from various foods such as fish, milk, eggs, meat, and legumes. Proteins play a vital role in the processes of biology and make living tissues. Hemoglobin, enzymes, and antibodies are the proteins examples. Amino acids find out the function and activity of the protein. Proteins vary from each other by their composition of amino acids and location, spatial configuration, function, and sequence. Most of these are structural components for example keratin while others work as enzymes. (2)

Protein is essential for good health. Additionally, the name derives from the Greek word proteos, which means “first place” or “primary”. Amino acids are made up of protein that combines them to make long chains. You can assume a protein as a thread of bead from a single bead is an amino acid. Several various proteins in the human body help in proper functioning. Proteins perform most of their action in the body cell and work different jobs. Here are some important functions of protein in the human body: (3)

Makes Biochemical Reactions

Protein is the enzyme that helps the thousands of the reactions of biochemical that occur outside and within your cells. The enzymes structure lets them associate with the other molecules within the cells known as substrates that catalyze reaction which is significant to your metabolism. An enzyme also plays a role outside the cell-like digestive enzymes such as sucrose and lactase that aid digest sugar. Few enzymes also need other molecules, including minerals or vitamins for a response to occur. The improper or lack of function of such enzymes cause disease. Body functions that rely on enzymes such as:

  • Blood clotting
  • Digestion
  • Muscle contraction
  • Energy production
