The average estimated cash rent was $202 per acre on top quality land, $161 per acre on average quality land, and $124 per acre on poor quality land. This was an increase in rental rates of 2.0% for top quality land, 1.9% for average quality land, and 2.5% for poor quality land.
R-Group. In solution it is the nature of the amino acid R-groups that dictate structure-function relationships of peptides and proteins.
Explain how a peptide bond forms between two amino acids. A peptide bond links the carboxyl group of one amino acid with the amino group. List and describe the three major components of an amino acid. Explain amino acids may be grouped according to the physical and chemical properties of the R group. At the pH in a cell, the amino and carboxyl groups are usually ionized.
