Title: Polymers, Monomers, and Lipids


1
Polymers, Monomers, and Lipids
Lipid monomers are less persistent than the above
monomers
Consequently, lipids are less-readily described
using the same polymeric terms (other than
triacylglycerides, well ignore lipid synthesis)
2
Various Lipids
Fat
Steroid hormone
Fatty acid
Sex hormone
Palmitic acid
Testosterone
Triacylglycerol
Estrogen
Lipids do not share a common core structure
Triglyceride
Waxes
Saturated fatty acid
Lard
Unsaturated fatty acid
Omega-3-fatty acids
Monounsaturated fatty acid
Free fatty acids
Trans fatty acid
Butter
What is common to lipids is their hydrophobicity
Polyunsaturated fatty acid
Margarine
Stearic acid
Olive oil
Oleic acid
Flax seed oil
Oil
Toasted Sesame oil
Phospholipid
Bile salts
Phosphatidylcholine
Vegetable shortening
Steroid
Hydrogenated vegetable shortening
Cholesterol
Partially hydrogenated veg. short.

Solid at Room Temp.
Liquid at Room Temp.
Greater High-Temp. Stability
Greater Low-Temp. Fluidity
