#Unit 2. Cellular Organization

Two types of plant peroxisomes:

Present in leaves - participates in photorespiration.

Present in germinating seeds (glyoxysomes) - converts fatty acids into sugars.

Plasmalogens

• most abundant class of PL in myelin sheaths

• Analogous to PC

• Contain an unusual fatty alcohol that is attached through an ether linkage.
