Biomolecules

Carbohydrates
Contains Hydrogen, Carbon and Oxygen in a 1:2:1 ratio. The polysaccharides which are polymers, are starches, and the monosaccharides which are monomers are sugars. Carbohydrates are the main source of energy in most living things
Functions - Used to build structures of the bodies of some plants and animals.
Examples - Cereal, crackers, and bread products.
Proteins
Proteins are made of carbon, hydrogen, nitrogen, and oxygen. Their monomers are amino acids, and the polymers are just proteins. Proteins must have a specific shape to work.
Functions - They increase speed of chemical reactions, create hormones, and transport molecules.
Examples - Meat, beans, and eggs.
Amino Acids (Monomer)
Amino Acids (Monomer)
Protein (Polymer)
Nucleic Acids
Nucleic acids contain hydrogen, carbon, oxygen, nitrogen, and phosphorus. The monomers are nucleotides, and the polymers are DNA and RNA.
Functions - Carries genetic material.
Examples - Adenine, thymine, and guanine
Lipids
Lipids are made of carbon and hydrogen. The monomers are glycerol and fatty acids, and the polymers are just lipids.
Function - Long term energy storage, make up cell membrane, and signaling.
Examples - Milk, cheese, and meat. All contain saturated fat.
