chained carbon
Oleic acid
C atoms are numbered from the carboxy
C (C1)
C atoms adjacent to the carboxyl C (C2, C3, C4) are known as α
β, γ respectively and the terminal
methyl (CH3 ) C is known as the
ω– or n-carbon.
Various conventions use (blank) for indicating the number and position of the double bond

Prostaglandin
Prostaglandins Synthesized in vivo by cyclization of the center of the carbon chain of arachidonic acid to form a
cyclopentane ring
