Lipids Vocab

Molecules that have a glycerol base

• Oils

• Lipids

• Glyceride

• Fats

Organic molecules that consist of a carbon chain with a carboxyl group at one end. Can be saturated or unsaturated.

• Triglyceride

• Fatty Acids

• Phospholipid

• Fats

Answer explanation

Neutral in nature. Fats fall into this category meaning that they have an even distribution of electrons across the molecule and do not have regions of partial positive or partial negative charge.

• Unsaturated

• Saturated

• Essential Fatty Acids

• Nonpolar

Cluster of lipid and protein molecules. Cholesterol is transported throughout the body by these.

• Antioxidants

• Adipose Tissue

• Lipoproteins

• Plaque

One atom of hydrogen and one atom of oxygen. One way to write the chemical formula -OH and is usually found attached to organic compounds converting them into important substances.

• Hydroxyl Group

• Phospholipid

• Lipid

• Glyceride

This is the temperature at which a substance changes from a solid to a liquid. The numbers of hydrogen and carbon atoms on a fatty acid chain determine the temperature at which lipids liquefy.

• Flash Point

• Hydrogenation

• Melting Point

• Smoke Point

a colorless, odorless, viscous liquid that is sweet-tasting and non-toxic found in plant and animal sources. The backbone is found in lipids known as glycerides.

• Unsaturated

• Glycerol base

• Marbeling

• Hydrogenation

Category of organic compounds that are insoluble in water and have a greasy feel. Examples are: fats, oils, shortening, phospholipids, sterols, and cholesterol.

• Lipids

• Diglycerides

• Fats

• Oils

A basic type of lipid with a glycerol base with two fatty acids and a phosphorus-containing acid attached. An example: egg yolks contain this, and are used in mayonnaise to keep it from separating.

• Monounsaturated

• Omega fatty acids

• Phospholipid

• Lipoproteins

Temperature at which lipids will flame.

• Flash point

• Smoke point

• Hydrogenation

• Rancidity
