Definition: A type of disease that affects certain insect larvae and crustaceans, caused by specific viruses, leading to tissue breakdown and the presence of virus particles in the body fluids.

Example: The farmer noticed signs of polyhedrosis in his caterpillar population, indicating a viral infection.

Definition: Describing a chemical compound that has multiple hydroxyl groups in its structure.

Example: Glycerol is a polyhydroxy compound commonly used in cosmetics.

Definition: A type of compound made up of repeating units that contain carbonyl groups, often produced by bacteria and fungi, and used in medicine for their antibiotic and other health-related properties.

Example: Polyketides are important in the development of new antibiotics and cancer treatments.

Definition: A type of protein made up entirely of lysine amino acids.

Example: Polylysine is often used in biochemistry for its ability to bind to negatively charged surfaces.

Definition: Relating to a person who has knowledge in many different subjects or fields.

Example: Leonardo da Vinci is often considered a polymathic genius due to his expertise in art, science, and engineering.

Definition: Relating to or made of a substance that consists of large molecules formed by the bonding of many smaller units called monomers.

Example: The new material is polymeric, making it flexible and durable.

Definition: A chemical process in which small molecules called monomers join together to form a larger molecule known as a polymer.

Example: The polymerisation of the monomers resulted in a strong and flexible material.

Definition: To undergo a chemical process in which small molecules combine to form a larger, more complex structure called a polymer.

Example: The scientists studied how the materials polymerise when exposed to heat.
