3) living system are actively engaged in energy transformations.
4) living systems have a remarkable capacity for self-replication.
simple organic compounds that are intermediates in cellular energy transformation and in the biosynthesis of various sets of building blocks: amino acids, sugars, nucleotides, fatty acids, and glycerol.
1) amino acids
4) fatty acids
5) and glycerol.
Chlorophyll a (Planar)
Interactions among macromolecules les to the next level of structural organization, known as Supramolecular complexes.
the respiratory of genetic information as contained within the linear sequences of nucleotides in the DNA of chromosomes.
are the "power plants" of cells by virtue of their ability to carry out the energy-releasing aerobic metabolism of carbohydrates and fatty acids, capturing the energy in metabolically useful forms such as ATP.
Van der Waals forces
are the result of induced electrical interactions between closely approaching atoms or molecules as their negativity charged electron clouds fluctuate instantaneously in time.
Van der Waals contact distance
the interatomic distance that results if only Van der Waals forces hold two atoms together.
form between a hydrogen atom covalently bonded to an electronegative atom (such as oxygen or nitrogen) and a second electronegative atom that serves as the hydrogen bond acceptor.
are the result of attractive forces between oppositely charged structures, such as negative carboxyl groups and positive amino groups.
