Which three elements are found in all monosaccharide sugars?
A
Carbon, hydrogen, and oxygen
B
Carbon, nitrogen, and oxygen
C
Carbon, phosphorus, and hydrogen
D
Hydrogen, oxygen, and sulfur
Verified step by step guidance1
Step 1: Begin by understanding the structure of monosaccharides. Monosaccharides are the simplest form of carbohydrates and are composed of atoms that form the backbone of their molecular structure.
Step 2: Recall the general chemical formula for monosaccharides, which is typically expressed as \( C_xH_{2x}O_x \). This indicates that monosaccharides are composed of carbon (C), hydrogen (H), and oxygen (O).
Step 3: Eliminate options that include elements not typically found in monosaccharides. For example, nitrogen (N), phosphorus (P), and sulfur (S) are not part of the basic structure of monosaccharides.
Step 4: Confirm that the correct answer must include carbon, hydrogen, and oxygen, as these are the three elements universally present in all monosaccharide sugars.
Step 5: Conclude that the correct answer is 'Carbon, hydrogen, and oxygen' based on the chemical composition and structure of monosaccharides.
