As basic building blocks of life, all living organisms use nucleic acids, proteins, lipids, and carbohydrates, as well as a variety of small molecules such as metabolites, messengers, and energy carriers.
Nucleic acids
macromolecules essential for the storage and transmission of genetic information in living organisms. Made up of simple unit of nucleotides.
Cholesterol
a fatty substance that is essential for building cells and producing certain hormones in the body.
Carbohydrates
________ are organic compounds that contain carbon, hydrogen, and oxygen.
Haemoglobin
________ is a molecule in the blood that helps distribute oxygen to the tissues in the body.
Hydrolysis
________ is when polymers can also be broken down into monomers.
Monosaccharides
