Double bond
Double bond is a type of covalent bond in which each atom shares two electrons with another atom within a molecule. For example,molecules with double bonds include oxygen molecules and carbon dioxide molecules.

Single bond is a type of covalent bond in which each atom shares one electron with another atom within a molecule. For example,molecules with single bonds include hydrogen molecules, fluorine molecules, and methane molecules.
The hoof is the hard horny nail on the toe of a horse or cow. The horny substance of the hoof is made of a protein called keratin.
Malic acid is a type of organic acid found in vegetables, fruits, dried plums, and vinegar. It inhibits active oxygen, reduces inflammation, and relaxes nerves and muscles.
Acetic acid is the main ingredient of vinegar sourness, a colorless liquid with a pungent odor and sour taste. In living organisms, it is an important component of substance metabolism.
Citric acid is a type of sour ingredient found in vinegar and citrus fruits. It is an essential ingredient for human life, as this acidic component metabolizes sugar in the body to produce important energy.
Organic compounds are substances that have a carbon atom backbone and can form complex molecular structures by bonding with various elements. Due to the presence of multiple functional groups, organic compounds can form molecules with widely varying chemical properties and reactivity.
Substrate is the substance upon which an enzyme acts. The substrate binds to the enzyme’s active site and is transformed into a product. Enzymes typically exhibit substrate specificity, meaning each enzyme usually acts only on a particular substrate.
Inorganic compounds are chemical compounds that do not have carbon as their basic framework. These compounds either lack carbon atoms altogether or consist of simple carbon compounds (such as CO2 and CaCO3).
DNA polymerase is an enzyme that uses single-stranded nucleic acid as a template to catalyze the synthesis of a DNA strand with a complementary base sequence. It functions primarily during DNA replication and repair.
