WebProteins contribute to the biochemical processes that preserve life. Proteins are complex macromolecules (polymers). They have high molecular weight and are made up of structural units (monomers) called amino acids. Amino acids are the protein’s building units. They are organic compounds made up of hydrogen, oxygen, carbon and nitrogen atoms. cub foods hours thanksgivingWebPolymers are poor conductors of heat and electricity, hence they are good thermal and electrical insulators. These properties are extremely useful for insulating electrical wiring as they prevent electric shocks and overheating.
