Study Notes
Monosaccharides
- Glucose, Fructose, and Galactose are examples of monosaccharides.
- Ribose and Deoxyribose are monosaccharides found in RNA and DNA respectively.
- Glucose and Fructose are isomers, meaning they have the same number of atoms but different arrangements.
Proteins
- Proteins are large biological molecules.
- Quaternary structure results from the association of four protein subunits.
Nucleic Acids
- A sugar-phosphate backbone is formed by covalent bonding between the phosphate of one nucleotide and the sugar of the next nucleotide.
- Nitrogenous bases extend from the sugar-phosphate backbone.
Fats
- Fats are lipids made from glycerol and fatty acids.
- Fats are important for energy storage and contain twice as much energy as a polysaccharide.
- Unsaturated fats have fewer than the maximum number of hydrogen atoms.
