The first phospholipid identified in biological tissue was:
Correct answer: A. Phosphatidylcholine
- A. Phosphatidylcholine
- B. Lethanolamine
- C. Phosphatidylserine
- D. Phosphatidic acid
Explanation
The first phospholipid identified in biological tissues was phosphatidylcholine, also known as lecithin. Theodore Nicolas Gobley discovered it in 1847 in the egg yolk of chickens. This marked a significant milestone in biochemistry, as phosphatidylcholine plays a crucial role in cell membrane structure and function. The other options, phosphatidylethanolamine, phosphatidylserine, and phosphatidic acid, were identified later and did not hold the distinction of being the first discovered phospholipids.

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
