Question

match each macromolecule to the correct picture.
monosaccharides
polysaccharides
fatty acid
triglycerides
phospholipids

Explanation:

• Monosaccharides: Simple sugar units, often represented as single-ring or small molecular structures (e.g., the small ring - like or simple molecular - looking diagram, maybe the fourth or a small single - unit diagram).
• Polysaccharides: Long chains of monosaccharides, so the diagram with many connected ring - like structures (the second diagram with clustered rings) as they are polymers of sugars.
• Fatty acid: Long hydrocarbon chains with a carboxyl group, the third diagram with a long chain of carbons and a carboxyl - like group at the end fits.
• Triglycerides: Formed from glycerol and three fatty acids, the fifth diagram with a glycerol - like head and three fatty - acid - like tails (the blue head with three red tails) matches.
• Phospholipids: Have a phosphate - containing head and two fatty - acid tails, the first diagram with a polar head (the colored top part) and two non - polar tails (the lower chains) is correct.

Answer:

• monosaccharides: The small single - unit or ring - like diagram (e.g., the fourth diagram with a single - unit structure).
• polysaccharides: The second diagram with clustered ring - like structures.
• fatty acid: The third diagram with a long carbon chain and a carboxyl - like group.
• triglycerides: The fifth diagram with a blue head and three red tails.
• phospholipids: The first diagram with a polar head and two non - polar tails.
