The Macromolecules of Life: Proteins, Carbohydrates, and Lipids
The cells of living organisms are composed of large molecules (macromolecules) sometimes also referred to as organic molecules because of the presence of the element carbon. Very many of the organic molecules found in living organisms are carbohydrates, proteins, lipids, and nucleic acids. Each of these macromolecules is made of smaller subunits. The different molecules have different chemical properties. For example, monosaccharides such as glucose will react with a chemical agent called Benedict’s solution but disaccharides, like sucrose, and polysaccharides, like starch will not. Similarly, proteins will react with a mix of potassium hydroxide and copper sulfate but free amino acids, carbohydrates, and lipids will not.
Mark: Drop Everything; Empty Hands, Open Hands October 27, 2019 — Costa Mesa As we step into following Jesus, we discover the “drop everything” is an ongoing process of releasing everything that gets in the way of our becoming like Him. (1-11) The barren fig-tree cursed, The temple cleansed. (12-18) Prayer in faith. (19-26) The priests and elders questioned concerning John the Baptist. (27-33)1-11 Christ's coming into Jerusalem thus remarkably, shows that he was not afraid of the power and malice of his enemies. This would encourage his disciples who were full of fear.

Today, we will focus on three of these molecular types: lipids, proteins and carbohydrates. You will work with nucleic acids in another lab. You may want to review the properties of the biomolecules of life.
