Biological polymers(carbohydrates,proteins, and nucleic acids) are all formed and broken by two processes. Identify the process and explain what is happening in them in 25 words or less(total).

Stereochemistry in biological molecules is often denoted by the D- and L- convention, instead of the R- and S- configurations determined by the Cahn-Ingold-Prelog methodology. Naturally occurring α-amino acids are typically in the L-configuration. The Fischer projection of L-alanine is shown. L-alanine H₂N- H3C- HOOC Identify which structures are equivalent to the L-configuration. H COOH H CH3 NH₂ -COOH NH₂ CH3 -H CH3 COOH H -NH₂ H₂N- H CH3 COOH NH₂ H CH3 -COOH

Reaction 1 H Monomer Reaction 2 H H OH + H H H₂O H H₂O OH + H H OH OH + H H₂O H₂O OH OH + H OH OH OH OH B) What are the main chemical interactions that determine and maintain the quaternary structure of proteins. Also, what are the conditions that can alter these interactions? [
