Answer 2

Lipid is a more general term refering to anything that dissolved in an organic solvent.Lipids could be fats, oils, sterols, some vitamins, and waxes ( long chained alcohols ). One example of a lipid that is a free fatty acid is the polyunsaturated fat Linoleic acid, and omega-6 fatty acid with a chemical formula of C18H32O2. This particular molecule has a COOH group at one end that is acidic, and a methyl group at the other.

Answer 3

While there are several different classes of lipids, we will mention only three major categories. 1. Triglycerides ( or neutral fat)s

Lipids. Lipids are one of the four major building blocks of life, along with ...

Answer 4

Dietary Forms with Type Description

1-Fatty Acid

Hydrocarbon chain with carboxylic acid

2-Saturated

· Has maximum number of hydrogens on the carbon chain

· Solid at room temperature

· High melting point

· Found in meats, poultry, and dairy foods; coconut and palm oils

3-Trans

· Product of hydrogenation which increases the saturation of fatty acids within oils and converts natural cis to trans configuration

· Consist of straighter chains than natural unsaturated fatty acids

· Industrial process that chemically transforms a low melting point oil into a solid fat with a higher melting point to enhance product taste, stability and shelf life.

· Found in commercially fried foods, commercial baked goods and snacks, margarine, and vegetable shortenings

4-Monounsaturated

· Contain one double bond

· Liquid at room temperature.

· Found in olive, peanut and canola oils; nuts, avocados, and olives.

5-Polyunsaturated

· Contain two or more double bonds

· Liquid at room temperature.

· Found in corn, soybean, safflower and sunflower seed oils, and fish.

· w (omega) 3 FATTY ACIDS:

1) Linolenic acid (18:3w3)

2) Eicosapentaenoic acid (20:5w3)

3) Docosahexaenoic acid (22:6w3)

· w (omega) 6 FATTY ACIDS

1) Linoleic acid (18:2w6)

2) Arachidonic fatty acid (20:4w6)

· ESSENTIAL FATTY ACIDS (must be obtained from the diet)

1) Linoleic acid (18:2w6)

2) Linolenic acid (18:3w3)

6-Triglycerides

· Neutral esters of glycerol and fatty acids

· Most contain different types of fatty acids (mixed)

· Most common form of dietary fats and oils
