bio-biochemisty

atom

the smallest unit of a chemical element that retains the properties of that element

ion

an atom or molecule with a net electric charge due to the loss or gain of one or more electrons.

octet rule

atoms want to gain,lose or control elections until their valence shell is full

ionic bond

transfer of electrons (stealing) metal to nonmetal which creates ions

covalent bond 

strong bonds (both atoms holding onto each other)

solvent

dissolves substance (liquid)

solute

what is dissolved (solid)

solution

solute+solvent

electronegativity

the degree to which an element tends to gain electrons and form negative ions in chemical reactions.

hydrogen bond

chemical bond formed when a positively charged hydrogen atom is attracted to a nearby electronegative atom

organic compound

a chemical compound that contains carbon atoms, typically bonded to hydrogen atoms.

biomolecule

essential for life, playing crucial roles in the structure, function, and regulation of cells and organisms

polymer

built out of many repeated pieces linked together

monomer

the 1 piece that is repeated

chitin

(artheripods and fungi) structure (exoskeletons +cell walls)

phospholipid bilayer

cell membrane, 2 layers of lipids

denature/denaturization

the unfolding of a protein into a polypeptide chain

catalyst

a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change.

digestive enzyme

breaks down molecules

synthesis enzyme

builds molecules

gene

DNA instructions on everything (hair, eye color, skin color)
