Lipids

• Fats
• Oils
• Waxes
• Steroids
• Phospholipids

Yes

They are Hydrophobic (water fearing)

Because they all have Large Sections which are Hydrocarbons (just Hydrogen and Carbon)making them Non-Polor

Glycerol and 3 Fatty Acids

Dehydration Synthesis 3 times

3 Hydrolysis Reactions

• Energy
• Aid in Absorption and Storage of Fat Soluble Vitamins (A,D,E, and K)
• Heat Insulation
• Protection and Cushion organs

• Saturated
• Solid at room temp
• Come from Animals

• Unsaturated
• Liquis at room temp
• Come from Plants

• The Hydrogen chains of Saturated Fatty Acids are Straight
• There are No Double Bonds
• Saturated Fatty Acids are packed together and tend to be solid

• Double bonds with Carbons makes the formation bent
• The Bonds tend to slide past one another therefore they can not form a tight bond

Hydrogenation

• The process of taking a Liquid Oil to a Solid Fat
• This is the conversion of Double Bonds to Single Bonds
• Never goes to full completion (all double bonds are not converted to single bonds)
• Double bonds not converted to single bonds are converted to Tran Fatty Acids and is bad for your health (hydrogens on eather side of the double bond)

• Trans
• There are Hydrogen atoms on either side of the double bonded carbon
• Trans arrangement tend to be more Solid than a normal unsaturated fatty acid
• May increase the chances of Heart Disease

• Waxes
• Phospholipids
• Steroids

• Waxes are Hydrophobic Lipids that are Solid at room temperatur and relatively hard.
• Functions of waxes in nature include Ear Wax that traps microorganisms, and wax is on plants to protect the plant against water loss.

They come from the Cell Membrane

All Steroids are composed of Four Hydrocarbon Rings, but differ in terms of Functional Group, for example Cholesterol is a Lipid that is a component of Cell Membrane, Testosterone is Male Sex Hormone, Aldosterone is a Hormone that regulates Water Balance, and Estrogen is Female Sex Hormone
