Detailed explanation-1: -A protein molecule is made from a long chain of these amino acids, each linked to its neighbor through a covalent peptide bond (Figure 3-1). Proteins are therefore also known as polypeptides.

Detailed explanation-2: -Hydrocarbons are organic molecules consisting entirely of carbon and hydrogen. We often use hydrocarbons in our daily lives: for instance, the propane in a gas grill and the butane in a lighter are both hydrocarbons.

Detailed explanation-3: -A fatty acid is a molecule composed of a carboxyl group attached to a long chain of carbon atoms bonded with hydrogen atoms. This is called a “hydrocarbon chain, ‘’ and it is a characteristic all lipids share. The hydrocarbon chain is also what gives lipids their nonpolar property and makes them insoluble in water.

Detailed explanation-4: -ORGANIC MOLECULES-BACKGROUND READING. Organic compounds contain carbon atoms linked together to form chains or rings. Four classes of organic compounds-carbohydrates, lipids, proteins and nucleic acids-are found in large amounts in living organisms.

Detailed explanation-5: -Proteins contain carbon, hydrogen, oxygen, nitrogen, and sulfur. A protein molecule is made from one or more long chains of amino acids, each linked to its neighbors by covalent bonds. Multiple chains of a protein are held together by weaker bonds. Proteins are the most numerous and diverse biochemical compounds.
