This document contains two passages about building biomolecules and their properties. The first passage discusses the six most abundant elements in biomolecules and how they bond to form organic molecules like hydrocarbons. It also defines isomers and explains polarity, electronegativity, and functional groups. The second passage defines monomers and polymers and how they link together. It describes the four main classes of biomolecules - lipids, carbohydrates, proteins, and nucleic acids - and lists some of their key properties and functions.
