Organic Compounds The basic units to build the modern cells involve organic chemicals such as carbohydrates, lipids, nucleotides, and amino acids. The macromolecules for supporting life such as DNA, RNA, and proteins are assembled from these basic units. The organized sum total of these molecules becomes a cell - a living entity. Living organisms use carbohydrates for energy, lipids for body fats, cell walls, hormones, nucleic acids for DNA in cells, and protein for skin, hair, muscles, hemoglobin, antibodies, enzymes.
All living things contain organic macromolecules: Lipids, proteins, carbohydrates and nucleic acids. Characteristic for these organic molecules is that they are made up of only a small number of elements: carbon, hydrogen, oxygen, and to smaller amounts nitrogen, phosphorus and sulfur. Proteins have many important roles in organisms. 2  Structural proteins such as collagen or elastin, provide support. 3  Regulatory proteins such as enzymes control cell processes. 4  Proteins also play an important part in the immune system (antibodies), oxygen transport (hemoglobin), movement (muscles) etc.
