Why are most Enzymes made of Proteins and not other Macromolecules?

Enzymes are biocatalysts that increase chemical reaction rates in cells without changing them (Palmer, 1991). In the absence of enzymes, most biological processes can not occur. The purpose of the enzyme is to allow the cells to function in time. Since the structure of most biomolecules plays a major role in its function, the three dimensional structure of the enzyme is involved in its catalytic activity. Therefore, the enzyme is a protein made of amino acids.

The enzyme is a hydrophilic globular protein polymer. Enzymes are biocatalysts that reduce the energy (including heat) required for chemical reactions, but also promote chemical reactions in the body but are not simply changing or changing, but simply chemical reactions necessary for life . Catalytic enzymes play a very important role in most other processes involved in metabolism, including digestion and cellular metabolism. These enzymes are mainly proteins

As with other biopolymers such as polysaccharides and nucleic acids, proteins are an important part of the body and are involved in almost all processes within the cell. Many proteins are enzymes that catalyze biochemical reactions and are essential for metabolism. Proteins also have structural or mechanical functions such as intramuscular actin, myosin, proteins within the cytoskeleton, forming a scaffolding system that maintains the shape of the cells. Other proteins are important in cell signaling, immune response, cell adhesion, and cell cycle. In animals, proteins are required during meals to provide essential amino acids that can not be synthesized. Digestion destroys proteins due to metabolism

Proteins are a kind of macromolecule that performs multiple functions on cells. They provide structural support and aid metabolism by acting as enzymes, carriers or hormones. The protein building block is an amino acid. Proteins are divided into four levels: primary, secondary, tertiary, and tertiary. The shape and function of proteins are complex and changes in shape caused by changes in temperature, pH or exposure to chemicals can lead to protein denaturation and loss of function.
