yeah

Test 2

SAPONIABLE- These can be broken down (hydrolyzed) using a strong base (like NaOH).

They contain ester bonds, which react with base to form soap.

Examples:

⦁ Triglycerides

⦁ Phospholipids (like phosphoglycerides)

⦁ Waxes

⦁ Triglycerides are three fatty acids attached to a glycerol molecule (glycerin).

⦁ Fatty acids, glycerolipids,glycerophospholipids,spingholipids,glycolipids

NON SPONIABLE- These cannot be broken down by base.

They do not contain ester bonds.

Texamples:

⦁ Steroids (like cholesterol)

⦁ Fat-soluble vitamins (A, D, E, K)

⦁ Terpenes

Test 4:

Essential fatty acid is needed in the body and must be obtained from the dietery sources since it cannot be synthesized within the body. These are the Linoleic acid and Linolenic acid. These fatty acids helps in the proper structure of membrane and serves as the starting material for the production of omega-6 and omega-3 acids. Linoleic acid which synthesizes the arachidonic acid(omega0i6 fatty acids) where it is the major starting material for eicosanoids, a substance that helps in regulating blood pressure, clotting, and several other important body function. And, Linolenic acid whicg synthesizes EPA AND DHA(omega-3 fatty acids) which are important in normal brain development. Also it activates the retina of the eyes.

(Essential fatty acids, like linoleic and linolenic acids, are needed by the body but must come from food since the body can't make them. Linoleic acid helps produce omega-6 fatty acids, which are important for blood pressure, clotting, and other functions. Linolenic acid makes omega-3 fatty acids like EPA and DHA, which support brain development and eye health.)

TEST 5:

PHOSPHOGLYCERIDES

⦁ The backbone is glcerol.

⦁ There are two esters formed with two fatty acids.

SPHINGOLIPIDS

⦁ The backbone is sphingosine.

⦁ Contains amide.
