For example, a carbohydrate is a macromolecule that is classified as a polymer because it is made up of repeating monosaccharides, but a fat (lipid) is a macromolecule that cannot be further classified …

Types of large biological molecules. Monomers, polymers, dehydration synthesis, and hydrolysis.

Nucleic acids, macromolecules made out of units called nucleotides, come in two naturally occurring varieties: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).

Chitin is a structural polysaccharide that occurs in many organisms. For example, chitin is found in the protective exoskeleton of arthropods, cell walls of fungi, and beaks of cephalopods such as squids …

Now for those of you who are familiar with the term you might associate it with things like fat molecules, and that would not be incorrect. Fat molecules are a very common form of lipid, in fact this is an …

Because of their polymeric nature and their large (sometimes huge!) size, they are classified as macromolecules, big (macro-) molecules made through the joining of smaller subunits.

As shown in the example above, the three fatty acid tails of a triglyceride need not be identical to each other. Fatty acid chains may differ in length, as well as in their degree of unsaturation.

This exoskeleton is made of the macromolecule chitin, which resembles cellulose but is made out of modified glucose units that bear a nitrogen-containing functional group.

Nucleic acids, crucial macromolecules for life, were first discovered in cell nuclei and exhibit acidic properties. DNA and RNA, composed of nucleotide building blocks, store hereditary information.
