Besides fibrous proteins, that have only one type of secondary structure, globular proteins, including enzymes, transport and structural proteins, some peptide hormones, and immunoglobulins, are folded structures much more compact than alpha (helices) or beta (sheets) conformations.
Moreover, globular proteins, with random or repetitive conformations, have roughly spherical shapes. Globular proteins usually exhibit little or no change untill a point is reached at which there is a sudden drastic change and, invariably, a loss of biological function (e.g., structural proteins) or their enzymatic activity (for enzymes), a phenomenon known as denaturation.
Finally, to understand the terciary structure of globular proteins there are two powerful techniques to do it: X-ray or neutron diffraction analysis of single crystals, and NMR analysis (Nuclear Magnetic Resonance) of small proteins in solution.
They are made up of proteins. They are globular proteins
There are two class of protein based on their structure namely fibrous and globular. Globular proteins form a globe like spherical structure in contrary to rod like fibrous proteins (collagen). They are soluble in water and the structure is rendered by its three dimensional arrangement of amino acids in solution. Most of the enzymes, soluble hormones and factors fall into this class of proteins.
Enzymes are globular in nature due to their specific three-dimensional folding, which is essential for their functional activity. This folding is driven by various interactions among amino acids, including hydrogen bonds, hydrophobic interactions, and ionic bonds. The compact, spherical shape allows enzymes to efficiently interact with substrates and catalyze biochemical reactions, ensuring that active sites are properly oriented for optimal binding. Additionally, the globular structure enables enzymes to remain soluble in cellular environments.
The link is that a metabolism is made up of different reactions and these reactions have to be catalyzed by enzymes, because without these enzymes most of the reactions in the metabolism wouldn't proceed.

Many enzymes consist of a protein and a non-protein (called the cofactor). The proteins in enzymes are usually globular. This is the tertiary structure of a protein. These globular proteins include enzymes and immunoglobins. The structures are held in place by hydrogen bonds, disulfide bridges and ionic bonds.
