Describe the similarities and differences between lecithin and cephalins.

Short Answer

Expert verified
  • Choline is an amino alcohol that can be found in lecithin.
  • As an amino alcohol, cephalins contain serine or ethanolamine.

Step by step solution

01

Introduction.

Lecithin is a fat combination which is required by human cells. It can be found in a variety of foods, including soybeans and egg yolks.

Cephalins are phosphoglycerides that contain ethanolamine or the amino acid serine, both of which are linked to the phosphate group by phosphate ester bonds.

02

Given Information.

Explain the differences and similarities between lecithin and cephalins.

03

Explanation.

Choline is an amino alcohol that can be found in lecithin.

As an amino alcohol, cephalins contain serine or ethanolamine.
