Verified step by step guidance

Step 1: Begin by understanding the definition of carbohydrates. Carbohydrates are organic molecules composed of carbon (C), hydrogen (H), and oxygen (O), typically in a ratio of 1:2:1. They serve as a primary energy source and structural components in living organisms.

Step 2: Review the classifications of carbohydrates. Carbohydrates are categorized into three main types: monosaccharides (simple sugars like glucose), disaccharides (two monosaccharides linked together, such as sucrose), and polysaccharides (long chains of monosaccharides, such as starch or cellulose).

Step 3: Examine the term 'lipids.' Lipids are a distinct class of biomolecules that are hydrophobic or amphipathic. They include fats, oils, phospholipids, and steroids. Unlike carbohydrates, lipids are not composed of repeating sugar units and are primarily involved in energy storage, membrane structure, and signaling.

Step 4: Compare the given options. Monosaccharides, disaccharides, and polysaccharides are all types of carbohydrates, as they are composed of sugar units. Lipids, however, are not classified as carbohydrates because they have a different chemical structure and function.

Step 5: Conclude that the biomolecule type NOT classified as a carbohydrate is 'Lipids,' based on their distinct properties and functions compared to carbohydrates.
