Study Notes
Carbohydrates
- Common dietary sources of carbohydrates include potatoes, bread, pasta, and rice.
- Carbohydrates are essential macronutrients providing energy.
D-Glucose
- The "D" in D-glucose indicates the orientation of the hydroxyl group on the chiral carbon that is furthest from the carbonyl group in the molecule's chain.
- It plays a crucial role in distinguishing glucose forms.
Glycosidic Bonds
- Monosaccharides are linked together in di- and polysaccharides via glycosidic bonds.
- These bonds are essential for forming complex carbohydrates from simple sugars.
Peptide Bonds
- A peptide bond connects the carboxylic acid group of one amino acid to the amino group of another, resulting in the release of a water molecule (H2O).
- This bond is fundamental in protein synthesis, forming the backbone of protein chains.
Protein Structures
- The primary structure of proteins involves the linear sequence of amino acids connected by peptide bonds.
- The secondary structure consists of the coiling (alpha helix) or folding (beta pleated sheet) of the peptide chain, which contributes to the protein’s overall shape and functionality.
