Definition: A type of molecule that is part of a larger compound, usually formed when a sugar is removed from a glycoside, leaving behind a non-sugar component.

Example: The aglycon of the compound was identified as a phenolic compound after hydrolysis.

Definition: A part of a molecule that is not a sugar, which is formed when a glycoside is broken down. It can be an organic compound like a phenol or alcohol that is linked to a sugar.

Example: In biochemistry, the aglycone is crucial for understanding the properties of glycosides.

Definition: Describing something that does not have any angles or sharp corners.

Example: The agonic line is a term used in navigation to describe a line of zero magnetic declination.

Definition: A sharp, pointed shape, often referring to a needle-like peak of a mountain or a tool used for drilling holes.

Example: The climbers reached the summit of the aiguille after a challenging ascent.

Definition: A part of an airplane wing that can move up and down to help control the aircraft's direction, especially when turning.

Example: The pilot adjusted the aileron to initiate a smooth turn during the flight.

Definition: A structure, like a wing or blade, that is shaped to create lift or control movement when it moves through the air.

Example: The engineer designed a new airfoil to improve the aircraft's lift efficiency.

Definition: The main structure of an aircraft, which includes the body and wings, but does not include the engines or other systems.

Example: The engineers designed a new airframe to improve the aircraft's aerodynamics.

Definition: The state or quality of being completely sealed so that no air can enter or escape.

Example: The airtightness of the container ensures that the food stays fresh for a longer time.

Definition: A type of amino acid that is found in many proteins and is important for various biological processes in the body.

Example: Alanine is one of the 20 amino acids used by cells to synthesize proteins.

Definition: A chemical group that comes from the amino acid alanine, consisting of a specific arrangement of atoms. It is often involved in the structure of proteins.

Example: In biochemistry, alanyl is often used to refer to the residue of alanine in proteins.
