Molecule: containing a huge amount of atoms.
A macromolecule is a biopolymers such as carbohydrates, proteins, lipids, and nucleic acids.
A carbohydrates or carbs is made up of carbon hydrogen oxygen. The subunit it monoascharride. The carbohydrates is used for short term energy and also it structures the exoskeletons. Some examples include; mono-glucose, di- sucrose lactose poly-starch, cellulose glycogen. A special characteristic is it usually ends in ose.
Proteins are composed of carbon hydrogen oxygen nitrogen sulfur. They are used for hair, digestion, nails and they also carry oxygen in your blood. Some examples include hemaglobin, enzymes, kreatin , and antibodies. Some special characteristics are the peptide bond (covalent). Finally, the subunit is amino acids.
These are made up of Carbon hydrogen oxygens. They are used for insulation, long term energy storage, helps protect organs and immunity. Also, some examples include; waxes, oils, steroids, (cholesterol, estrogen, and testerone heroin. ) The subunit is fatty acids and glycerol. The special characteristics are non- polar and hydrophobic.
Nucleic acids include; DNA, RNA, and ATP. Which are all made up of carbon hydrogen, oxygen nitrogen and phosphorus. They are used to make the proteins. Also they are found in every nucleus in the cell. Nucleotides is its subunit.
