Chem of Life Flashcards
Ion
atom with an uneven number of protons and electrons
cation
positively charged ion
anion
negatively charged ion
ionic bond
Formed when one or more electrons are transferred from one atom to another
polar covalent bond
A covalent bond in which electrons are not shared equally
nonpolar covalent bond
a covalent bond in which the bonding electrons are shared equally by the bonded atoms, resulting in a balanced distribution of electrical charge
phospholipid
a lipid that contains phosphorus and that is a structural component in cell membranes
triglycerides
an energy-rich compound made up of a single molecule of glycerol and three molecules of fatty acid.
saturated
Fats with the maximum number of hydrogens.
unsaturated
Fat with less than the maximum number of hydrogens in one or more of its fatty acid chains
protein
An organic compound that is made of one or more chains of amino acids and that is a principal component of all cells
cells use it for everything
nucleic acids
macromolecules that store genetic information and enable protein production
covalent bond
electrons shared between atoms
hydrogen bond
Bond between H of polar covalent bonds (slightly pos) and another atom of polar covalent bond (slightly neg)
monomers
single molecular unit of a polymer
building blocks of polymers
