Expert Solution

Step 1: Proteins and Carbohydrates
Proteins are high molecular weight, three-dimensional biochemical polymers that serve diverse functional roles within a cell. Proteins are folded polypeptides. Polypeptides are long chains of amino acid residues linked together via the peptide bond.
Chemically carbohydrates are polyhydroxy aldehydes or ketones. Based on their size they can be classified into:
- monosaccharides: single polyhydroxy aldehyde or ketone.
- disaccharides: two monosaccharides linked via a glycosidic bond.
- oligosaccharides: a short chain of monosaccharides linked via glycosidic bonds
- polysaccharides: monosaccharide polymers with 20 to 1000 or more units.
