This lecture covers fundamental concepts in biochemistry, including bioenergetics, protein structure, metabolic pathways, and modes of metabolism regulation. It delves into the chemistry of living systems, focusing on carbon molecules and water properties. Students will learn to calculate bioenergetic parameters, analyze protein structure, trace key metabolites, and compare metabolic regulation modes. The course emphasizes the importance of carbon chemistry in understanding cellular processes and metabolic pathways. Resources such as animations and detailed explanations are provided to aid comprehension.

Why Carbon What can we learn from this? • C – C bond is stronger than C – O • Stable in oxygen rich environment! • Two C – C bonds are stronger than one C = C • Chains are stable! • C – H bond is strong • Hydrocarbons stable at room temperature!
