The Cell and Its Environment

The Cell and Its Environment. Spring 2010. What is a cell?. A cell is the basic unit of living things. Some living things are composed of only one cell and are called UNICELLULAR organsims. Organisms that have many different cells are called MULTICELLULAR organisms.

Amide Bond Formation

Amide Bond Formation. Amide bonds form upon reaction of carboxylic acids with ammonia, primary amines or secondary amines. When amide bonds form between amino acids we call it a peptide bond. Amino Acids. Proteins. Proteins are polymers of amino acid monomers held together by peptide bonds.
