Draw the amino acids alanine ( r group-ch3) and serine
(rgroupch2oh) and then show how a dehydration
reactionwill form a peptide bond between them.

As shown in figure.

Explanation:

The dehydration reaction implies the appearance of water as a residue after the bond is formed.

The reaction is carried on in various steps, as shown in the figure below.

First, the oxigen in the carboxilic acid takes the pairing electron an debonds from the molecule, after which the amino in the other aminoacid attacks this positive charge and attachs to the first molecule.

The negatively charged hydroxyl group remaining attacks the hydrogen in the amino removing the positive charge ballancing the reaction and forming water, remaining a peptide bond between both aminoacids and lefting water as a residue.

1. loamy sand is about 80% sand with 10% clay and defined mostly by sand particles with some clay to provide structure and fertility. the sand particles are easily visible and the soil holds structure but breaks apart easily.

2. scott sand can improve his soil quality by incorporating more silt and organic matter into the soil. peat moss and organic matter can also be incorporated.
