Q. 15.81 - An Introduction to General, Organic, and Biological Chemistry

Question

15.81 Identify the components ($1$ to $6$ ) contained in each of the following lipids (a to d):

1. glycerol

2. fatty acid

3. phosphate

4. amino alcohol

5. steroid nucleus

6. sphingosine

a. estrogen

b. cephalin

c. wax

d. triacylglycerol

Step-by-Step Solution

Answer

( part  a) Estrogen - (5). Nucleus on hormone 

( part   b) Cephalins - (1). glycerol, glycerol, glycerol (2). The fatty acid (3). phosphorus (4). Alcoholic amino acid residues. 

(part   c) Wax - (2). the fatty acid. 

(part   d)  triacyiglycerol - (1). triglyceride, propylene glycol,  (2), the fatty acid.

Step 1: Introduction ( part a)

Lipids are found naturally components this included fats, waxes, and sterols. triglycerides, for illustration Cholesterol are fats that have included glycerol bonded to three fatty acids, such like fats and oils.     

Step 2: Given Information (part a)

 Steroids lack a fatty acid chain and then have a steroidal ring. 

Step 3: Explanation (part a)

(a) The steroidal core is formed by three six-membered rings and a five-membered ring joined combined.

Consequently, Estrogen - (5). Nucleus on hormone

Step 4: Given Information (part b)

Cephalins contain phosphatidylethanolamines and phosphatidyiserines.

Step 5: Explanation (part b)

(b) That are phospoacylglycerols. Polymer has to have a chromophore bonded to this now.

Accordingly, Cephalins - (1). triglyceride, propylene glycol,  (2). The fatty acid (3). phosphorus (4). Glutamate remnants containing alcohol.

Step 6: Given Information (part c)

Waxes are protracted alcohol derivatives of essential fatty acids. 

Step 7: Explanation (part c)

(c). Waxes are protracted alcohol derivatives of essential fatty acids.

Thus, Wax - (2). the fatty acid.

Step 8: Given Information (part d)

A tricarboxylic acid contains glycerol.

Step 9: Explanation (part d)

(d) The triglyceride for lipid synthesis is joined here to three fatty acids by such an ester bond, producing in either a "triglyceride or triacyigiycerol."

Consequently, triacyiglycerol - (1). glycerol, glycerol, glycerol (2). t he fatty acid
