Detailed explanation-1: -Enzymes are proteins comprised of amino acids linked together in one or more polypeptide chains. This sequence of amino acids in a polypeptide chain is called the primary structure. This, in turn, determines the three-dimensional structure of the enzyme, including the shape of the active site.
Detailed explanation-2: -Enzymes are mainly globular proteins-protein molecules where the tertiary structure has given the molecule a generally rounded, ball shape (although perhaps a very squashed ball in some cases). The other type of proteins (fibrous proteins) have long thin structures and are found in tissues like muscle and hair.
Detailed explanation-3: -Definition. An enzyme is a biological catalyst and is almost always a protein.
Detailed explanation-4: -Most enzymes are huge protein molecules. Highly specific, each usually catalyzes only one type of chemical reaction. Some enzymes consist of a protein and a helpful nonprotein component called a prosthetic group.
Detailed explanation-5: -For example, proteins can function as enzymes or hormones. Enzymes, which are produced by living cells, are catalysts in biochemical reactions (like digestion) and are usually proteins.
