Question

fatty acid nucleotide is a building block of triglycerides contains hydrogen has a phosphate group

Explanation:

• Triglycerides are made of glycerol and fatty acids. So, fatty acid is a building block of triglycerides.
• Both fatty acids (e.g., \(C_{n}H_{2n + 1}COOH\)) and nucleotides (e.g., composed of carbon, hydrogen, oxygen, nitrogen, and phosphorus) contain hydrogen.
• Nucleotides have a phosphate group as part of their structure (nucleotide = nitrogen - containing base + pentose sugar + phosphate group), while fatty acids do not.

Answer:

• Is a building block of triglycerides: Fatty acid
• Contains hydrogen: Fatty acid, Nucleotide
• Has a phosphate group: Nucleotide
