molecule

A group of atoms bonded together

photosynthesis

process by which plants and some other organisms use light energy to convert water and carbon dioxide into oxygen and high-energy carbohydrates such as sugars and starches

amino acid

monomer of protein

pH

A measure of a compound's acidity or strength as a base

sugar

a molecule of or containing glucose

lipid

macromolecule made mostly from carbon and hydrogen atoms; includes fats, oils, and waxes

nucleic acid

a complex organic substance present in living cells, especially DNA or RNA, whose molecules consist of many nucleotides linked in a long chain.

organic

Carbon-containing

inorganic

Not formed from living things or the remains of living things

carbon
