Humans cannot digest cellulose due to the absence of the enzyme cellulase, which is necessary to break down cellulose into glucose molecules. Cellulose is a polysaccharide and a major component of the cell walls in plants. It provides structural support to plants. In the human digestive system, cellulose acts as dietary fiber. While it is not digested and absorbed, it is crucial for maintaining a healthy digestive system, promoting bowel movements, and preventing constipation. The beneficial effects of fiber in the diet also include lowering cholesterol levels, regulating blood sugar, and aiding in weight management. Although humans cannot digest cellulose to absorb its constituent sugars for energy, the inclusion of cellulose as fiber in the diet has significant health benefits.
To draw molecular orbitals for 1,3-butadiene, start by acknowledging its structure: a four-carbon chain with two double bonds in conjugation. There are four π orbitals arising from the p_z atomic orbitals of the carbons. The constructive and destructive combinations of these atomic orbitals result in four molecular orbitals: two bonding (π and π2) and two antibonding (π* and π2*).
1. Begin with the four p_z atomic orbitals aligning above and below the plane of the carbon atoms.
2. Combine them constructively to form the lowest energy π orbital, where all lobes are in phase.
3. The next higher energy, π2, involves one node, with a phase change between the second and third carbon.
4. The π* (antibonding) introduces another node, and the lobes adjacent to the node are out of phase.
5. The highest energy, π2*, has two nodes with corresponding phase changes.
Graph these as diagrams showing the phase (plus or minus) of the orbitals, and indicate nodes. Highlighting the constructive and destructive interference helps to clarify the bonding and antibonding character of these molecular orbitals.
PVC, or Polyvinyl Chloride, is a widely used synthetic plastic polymer. It comes in two basic forms: rigid (used in construction for pipes, doors, windows, etc.) and flexible (used in clothing, electrical cable insulation, etc.). PVC is made through a process called polymerization, where vinyl chloride monomer (VCM) molecules are chemically combined under pressure and heat in the presence of a catalyst. This process forms long chains of PVC polymer. The addition of plasticizers makes PVC flexible. Its durability, low cost, and versatility make PVC a popular choice for various applications, despite environmental concerns over its production and disposal, which releases toxic chlorine-based chemicals.
