Fatty Acids, Lipids, Amines, and Amides

These flashcards cover key vocabulary related to fatty acids, lipids, amines, and amides, aiding in understanding their structures and functions.

Amphipathic

Molecules that have both polar (hydrophilic) and nonpolar (hydrophobic) parts.

Hydrophobic

Substances that do not interact well with water.

Hydrophilic

Substances that interact well with water.

Eicosanoids

Signaling molecules made from fatty acids that have various functions in the body.

Saturated Fatty Acid

Fatty acids that have no double bonds in their carbon chain.

Unsaturated Fatty Acid

Fatty acids that contain one or more double bonds in their carbon chain.

Lipoproteins

Complexes of lipids and proteins that transport lipids in the bloodstream.

Chylomicrons

Lipoproteins that transport dietary lipids from the intestines to other tissues.

HDL

High-Density Lipoprotein, often referred to as 'good cholesterol'.

LDL

Low-Density Lipoprotein, often referred to as 'bad cholesterol'.

Steroids

Lipid molecules with a structure composed of four fused rings.

Hydrogen Bond

A weak interaction occurring between a hydrogen atom and an electronegative atom.

Amine

An organic compound derived from ammonia by replacement of one or more hydrogen atoms by organic groups.

Primary Amine (1°)

An amine where one carbon atom is attached to the nitrogen atom.

Secondary Amine (2°)

An amine where two carbon atoms are attached to the nitrogen atom.

Tertiary Amine (3°)

An amine where three carbon atoms are attached to the nitrogen atom.

Amide

A compound formed from a carboxylic acid and an amine.

Amidation

The process of forming an amide by reaction between a carboxylic acid and an amine.

Aromatic Amine

An amine with an aromatic ring, commonly derived from aniline.
