Biomolecules and Water Properties

These flashcards cover key concepts and terminology related to biomolecules, water properties, and their significance in biological systems.

Covalent bond

A bond where atoms share electrons.

Polar

A type of bond with unequal sharing of electrons, as seen in water.

Nonpolar

A type of bond with equal sharing of electrons.

Hydrogen bond

A weak bond that occurs between polar molecules.

Amphipathic

Molecules that have both hydrophilic and hydrophobic properties, such as soap.

Cohesion

The property of water that causes it to stick to itself, aiding in blood flow.

Electrolytes

Substances that break apart in water, such as salt.

Nonelectrolytes

Substances that dissolve in water but do not break apart, such as sugar.

Phospholipids

Amphipathic molecules that form cell membranes.

Mixture

A combination of substances, classified as solution, colloid, or suspension.

Triglycerides

A type of lipid that serves as energy storage.

Nucleic acids

Biomolecules that include DNA and RNA, responsible for genetic information.

Amino acids

The building blocks of proteins.

Denaturation

The process by which a protein loses its shape due to factors like heat or pH.

ATP

Adenosine triphosphate, the energy currency of cells.

Carbohydrates

Organic compounds including sugars, categorized as mono, di, or polysaccharides.
