Part 1:
The reading assignment for this week introduced you to the four types of biological macromolecules. For each category of macromolecule (carbohydrate, lipid, protein and nucleic acid), a) select an example of the polymer and b) explain its biological function. c) Why is each macromolecule (carbohydrate, lipid, protein, and nucleic acid) characteristic of the class of molecules it belongs to? Discuss their monomer subunits, basic chemical structure, and how the monomers are connected to one another.

The chemical connection formed between amino acideates the essential connectivity in all protein structures. One amino acid's carboxyl group (COOH) joins with an another's amino group (NH2) to form the sequence CONH and release water in a peptide bond (H20). Phosphate groups and sugar residues alternately make up DNA strands, with the nitrogenous bases each connected to a distinct region of the sugar section. By creating hydrogen bonds between the phosphate group of one nucleotide and the sugar residue of the following one, a DNA or RNA strand can grow longer (Beck, 2018).
