Carbohydrates, Nucleotides, and Lipids

aldehyde, primary alcohol, ketone, secondary alcohol

ketone

Answer B

Saturated fatty acids

no carbon double bonds—→ all carbons have hydrogens

Answer B

1,2, 3

A. a decrease in LDL or ceramides

B. a degrease in glycolipids or increase in cholesterol

C. An increase in free omega 3 fatty acids or increase in sphingolipids

D. An increase int erpenes or a decrease in saturated lipids

Answer: C

decrease in LDL will help withatherosclerosis as stated in passage, but not Psoriasis where it needs increase ceramids (A)

decrease in glycolipids doesn’t do anything as nothing is mentioned of it, while icnreasing cholesterol doesn’t help with atherosclerosis (B)

How is lipid processed during digestion?

All lipids can be emulsified, and triglycerides and phospholipids are hydrolyzed

Answer: Low levels of testosterone

B. Carboxyl oxygen atoms in acetyl gorups form hydrogen bonds with nitrogenous bases

C. salt bridges between charged amino acids and phosphate groups are disrupted

D. lysine residues in histones associate with positive charged phosphate groups in DNA

Answer C

Answer C

What does glucosidase do?

Prostaglandin

Terpenes

precursors in the synthesis of cholesterol and steroid hormones

catecholamines are derived from

tyrosine and play a role in inflammatory responses but generally do so as endocrine signals

use true or false and then select the answer

A. true, dFTP is incorporated by KF as shown in graph

B. false, dFTP is incorporated and it isn’t watson crick

C. false, dFTP isn’t in the template (as shown in passage)

so answer is B

guanine

Phospholipids at higher temperatures increase fluidity as the kinetic energy of the phospholipids molecules increases. Adding saturated phospholipids (all with hydrogen) allow tight packing with other saturated fatty acids as it provides large surface area for london forces—> decreasing fluidity

Answer: And so, the sample with highest idodine value would be the 30ºC one. The lowest temp would decrease fluidity, having more unsaturated fatty acid would restores fluidity and it has double bonds.

Answer C
