Which statement describes how polymerization relates to proteins and amino acids?
many different proteins join together to form an amino acid.
many different amino acids join together to form a protein.
a single large protein breaks down to form many amino acids.
a single large amino acid breaks down to form many proteins.

The statement “Many different amino acids join together to form a protein” best describes polymerization. Amino acids are the basic molecules in proteins. Polymerization is the bonding of two or more molecules in order to create a larger molecule, which in this case is protein. The bonding agent between the amino acids is called the peptide bond.

For cyclohexane compounds drawn in a chair conformation:   -axial bonds are vertical  -equatorial bonds are parallel to two bonds within the ring.  thus, as i assume the chair conformation is drawn:   -the x group is in an axial position, as are the five other vertical bonds.  -three axial bonds are on the top face of the ring  -the other three axial bonds are on the bottom face  the position of the second substituent on each ring carbon is equatorial.  gauche groups must be on an adjacent carbon such as carbon 6 and carbon 2, and also gauche groups are rotated by 60 degrees relative to each other.  drawing the newman projections for c1–c2 and c1–c6 aids in visualizing the groups that are gauche to the y group on c1.  click this link and watch some academic videos that may you more understand the topic
