Chemistry and Biological Molecules Vocabulary

Vocabulary flashcards covering atomic structure, chemical bonds, acid-base balance, and biological macromolecules from the lecture.

Radioisotope

Unstable isotopes; high energy or radiation released by radioactive decay, allows Isotope to assume a more stable form

Ionic Bond

Formed when electrons ave transferred from a metal atom to a non-Metal atom, results in formation of ions Cations and anions

Covalent Bond

Strongest bond; form when two or more nonmetals shave electrons

Inorganic

Do not contain carbon bonded to hydrogen (small molecules with little enorg

Organic

Does contain carbon bonded to hydrogen (large molecules with lots of energy)

Hydrophilic

Contains fully or partially charged ends

Acidosis

When there is too much acid in your body fluids

Alkalosis

Where body fluids have an excess of base or alkali

Lipids

Group of nonpolar hydrophobic Molecules composed of carbon and hydrogen; include fats and oils

Proteins

Macromolecules that function as enzymes, play structural roles, are involved in movement, function in body's defenses, can be used as fuel

Nucleic Acids

Large biological molecules that stove and transmit genetic information in all living cells

Carbohydrates

Primary source of energy for the human body

Enzyme

Biological catalysts, mast are proteins

Catabolic

When a large substance is broken down into smaller substances

Anabolic

When small simple units and United by chemical bonds to make large more complex substances
