Lecithin and cephalins are the alternate names for:

Phosphatidylethanolamine and phosphatidylserine respectively

Explanation:

1. Introduction
Lecithin and cephalins are types of phospholipids that play important roles in various biological processes. They are essential components of cell membranes and are involved in processes such as cell signaling, membrane fluidity, and lipid transport.

2. Lecithin (Phosphatidylethanolamine)
Lecithin, also known as phosphatidylethanolamine, is a type of phospholipid that consists of a glycerol molecule, two fatty acid chains, a phosphate group, and an ethanolamine group. It is commonly found in cell membranes and is involved in membrane structure and function. Lecithin is also a major source of choline, which is a nutrient important for brain health and function.

3. Cephalins (Phosphatidylserine)
Cephalins, also known as phosphatidylserine, are a group of phospholipids that contain a serine amino acid instead of an ethanolamine group. Like lecithin, cephalins are important components of cell membranes and are involved in various cellular processes. They are particularly abundant in brain tissue and are believed to play a role in neurotransmitter release and cell signaling.

4. Alternate Names
According to the given options, lecithin is an alternate name for phosphatidylethanolamine, and cephalins are an alternate name for phosphatidylserine. This means that lecithin and phosphatidylethanolamine can be used interchangeably, as can cephalins and phosphatidylserine.

5. Conclusion
In conclusion, lecithin and cephalins are alternate names for phosphatidylethanolamine and phosphatidylserine, respectively. These phospholipids are important components of cell membranes and are involved in various cellular processes.
