Spread spectrum. In telecommunication and radio communication, spread-spectrum techniques are methods by which a signal (e.g., an electrical, electromagnetic, or acoustic signal) generated with a particular bandwidth is deliberately spread in the frequency domain, resulting in a signal with a wider bandwidth.
Lipids are one of the four major groups of organic molecules; the other three being proteins, nucleic acids (DNA), and carbohydrates (sugars). Lipids are made up of the same elements as carbohydrates: carbon, hydrogen, and oxygen.
Proteins are macromolecules made up of amino acid building blocks. There are thousands of proteins in organisms, and many are made up of several hundred amino acid monomers. Check out the table below for some examples of proteins in your body.Lipids are macromolecules that are made up of long chains of fatty acids, or carbon rings. Important lipids in your body include cholesterol, steroid hormones, triglycerides, and phospholipids.hink of a monomer as being a brick, and a polymer, or macromolecule, as being the whole brick wall composed of the building blocks. The brick wall is composed of smaller units-the bricks-just as a macromolecule is composed of monomer building blocks.
