Which of the following terms is least like the others?
a. Monosaccharide
b. Phospholipid
c. Fat
d. Steroid
e. Lipid
Verified step by step guidance1
Step 1: Begin by understanding the terms provided in the question. Monosaccharide, phospholipid, fat, steroid, and lipid are all biological molecules, but they belong to different categories based on their structure and function.
Step 2: Define each term: A monosaccharide is a simple sugar and the basic unit of carbohydrates. Phospholipids, fats, and steroids are types of lipids, which are hydrophobic molecules primarily involved in energy storage, membrane structure, and signaling.
Step 3: Recognize the relationship between the terms. Phospholipids, fats, and steroids are all classified as lipids, while a monosaccharide is not a lipid but a carbohydrate.
Step 4: Identify the term that is least like the others. Since monosaccharides are carbohydrates and not lipids, they are structurally and functionally distinct from the other terms listed.
Step 5: Conclude that the term 'monosaccharide' is the least like the others because it belongs to a different category of biological molecules (carbohydrates) compared to the rest, which are lipids.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Monosaccharides
Monosaccharides are the simplest form of carbohydrates, consisting of single sugar molecules like glucose and fructose. They serve as fundamental building blocks for more complex carbohydrates and are primarily involved in energy production and storage in living organisms.

Formation & Breakdown of Polysaccharides
Lipids
Lipids are a diverse group of hydrophobic organic molecules, including fats, phospholipids, and steroids. They play crucial roles in energy storage, cellular structure, and signaling. Unlike carbohydrates, lipids do not form polymers and are characterized by their insolubility in water.

Phospholipids, Fats, and Steroids
Phospholipids, fats, and steroids are all types of lipids. Phospholipids are key components of cell membranes, fats serve as long-term energy storage, and steroids function as hormones and signaling molecules. They share structural similarities, such as hydrophobic properties, distinguishing them from monosaccharides.
