Detailed explanation-1: -Carbon-based molecules have three fundamental structures-straight chains, branched chains, and rings.
Detailed explanation-2: -Carbohydrates and lipids are made of only carbon, hydrogen, and oxygen (CHO). Proteins are made of carbon, hydrogen, oxygen, and nitrogen (CHON). Nucleic acids such as DNA and RNA contain carbon, hydrogen, oxygen, nitrogen, and phosphorus (CHON P).
Detailed explanation-3: -Answer: The definition of a molecule is very specific and followed rigorously in chemistry. However, a biomolecule is a rather generic term used for molecules and ions that are present in living organisms.
Detailed explanation-4: -Carbohydrates contain only carbon, hydrogen and oxygen atoms; prior to any oxidation or reduction, most have the empirical formula Cm(H2O)n. Compounds obtained from carbohydrates by substitution, etc., are known as carbohydrate derivatives and may contain other elements.
