A biological molecule is a carbohydrate if it contains carbon, hydrogen, and oxygen in the molar ratio 1:2:1. The empirical formula for carbohydrates is CH2O. The monomers of carbohydrates are sugars. They are often used to form larger molecules.

How do you identify a carbohydrate?
Carbohydrates can be represented by the stoichiometric formula (CH2O)n, where n is the number of carbons in the molecule. Therefore, the ratio of carbon to hydrogen to oxygen is 1:2:1 in carbohydrate molecules. The origin of the term “carbohydrate” is based on its components: carbon (“carbo”) and water (“hydrate”).
What classifies a molecule as a carbohydrate?
What is a carbohydrate? A carbohydrate is a naturally occurring compound, or a derivative of such a compound, with the general chemical formula Cx(H2O)y, made up of molecules of carbon (C), hydrogen (H), and oxygen (O). Carbohydrates are the most widespread organic substances and play a vital role in all life.
Are biological molecules carbohydrates?
Carbohydrates: Carbohydrates are biological macromolecules that are further divided into three subtypes: monosaccharides, disaccharides, and polysaccharides. Like all macromolecules, carbohydrates are necessary for life and are built from smaller organic molecules.
What are the 3 classifications of carbohydrates?
A chemical approach divides carbohydrates into three main groups, sugars (DP1–2), oligosaccharides (short-chain carbohydrates) (DP3–9) and polysaccharides (DP⩾10). Sugars comprise (i) monosaccharides, (ii) disaccharides and (iii) polyols (sugar alcohols).
Which molecule is not a carbohydrate?
Which molecule is not a carbohydrate? A lipid is a hydrophobic polymer, not a carbohydrate.
How can you tell a biological molecule is a lipid?
How can you tell a biological molecule is a lipid? Lipids are insoluble in water and have a high proportion of nonpolar carbon-hydrogen bonds. They are composed of glycerol and fatty acids. In a saturated fat, all of the carbons are bonded to two or more hydrogens.
What are the three biological molecules?
Biomolecules have a wide range of sizes and structures and perform a vast array of functions. The four major types of biomolecules are carbohydrates, lipids, nucleic acids, and proteins.
What is a macromolecule identify the four types of biological macromolecules?
Types of Biological Macromolecules
- Biological macromolecules are important cellular components and perform a wide array of functions necessary for the survival and growth of living organisms.
- The four major classes of biological macromolecules are carbohydrates, lipids, proteins, and nucleic acids.
Which of the following is a way to recognize a carbohydrate by looking at its name only?
Which of the following is a way to recognize a carbohydrate by looking at its name only? ANSWER: It always ends in -ase. The largest carbohydrate molecules are called polysaccharides because they are composed of ________ molecules bonded together with one another.
