CC1 CARBOHYDRATES 2 MIDTERM

Question 1

• chemically diverse group of compounds with a general feature of insolubility in water
• composed of carbon-hydrogen bonds
• Have lower specific gravity than water

Answer 1

Lipids

Question 2

In LIPIDS, mostly are utilized for:

Answer 2

-Energy
-Structural elements
-Electron carriers
-Enzyme cofactors

Question 3

• Simple linear chains of C-H bonds that ends with a carboxyl group
• Majority are part of triglycerides or phospholipids
• Can be used for gluconeogenesis

Answer 3

Fatty Acids

Question 4

In plasma, only a few amount exist as free or
unesterified form and most are bound to

Answer 4

albumin

Question 5

• “Neutral Fat” or simply “Fats”
• Composed of 3 Fatty acids + Glycerol connected by Ester bonds
• Very hydrophobic
• The main storage lipid and used for energy
• constitutes 95% of tissue storage fat and are predominant form of glyceryl esters found in plasma

Answer 5

Triglycerides

Question 6

Breakdown of triglycerides is carried by:

Answer 6

• LPL
• Epinephrine
• Cortisol

Question 7

Advantages of Triglycerides as energy:

Answer 7

• Carbon atoms of fatty acids are more reduced than those of sugars
• Triglycerides are hydrophobic, and therefore unhydrated, the organisms that
  carries fat as fuel does not have to carry extra weight of water

Question 8

Triglycerides specimen:

Answer 8

-Serum or Plasma

Question 9

Triglycerides preparation:

Answer 9

-Fasting of 12-14 hours

Question 10

Triglycerides levels:

Answer 10

• Normal: <150 mg/dL
• Border: 150-199 mg/dL
• High: 200-499 mg/dL
• Very High: > 500 mg/dL

Answer 11
