Interpretation Introduction

Interpretation:

The two differences in the reactions for fatty acid synthesis and the reaction for fatty acid degradation should be described.

Concept introduction:

Fatty acids are aliphatic mono-carboxylic acids that are mostly obtained from the hydrolysis of natural fats and oils. They have a general formula R(CH2)nCOOH, n is mostly an even number of carbon atoms (4 to 20) with a few exceptions that have an odd number.

β-oxidation is the oxidation and splitting of two carbon units at β- carbon atom. This results in sequential removal of 2 carbon fragments as acetyl CoA until the complete oxidation of fatty acids.

The four important steps of β-oxidation are,

Step 1: Dehydrogenation of the fatty acyl-CoA to make ‘trans’ double bond between α and β carbon.

  • Short, medium and long chain acyl-CoAdehydrogenases
  • Electron removed transferred to FAD

Step 2: Hydration of the double bond.

Step 3: Dehydrogenation of the β-hydroxyl group to a ketone.

  • Electron removed transferred to NAD+

Step 4: Acylation-addition of CoA and production of and production of acetyl-CoA

Lipogenesis is the metabolic pathway by which fatty acids are synthesized from acetyl-CoA.

Lipogenesis requires;

Synthesis of fatty acids and glycerol

Activation of fatty acids by CoA and glycerol by glycerokinase

The combination of activated fatty acids and activated glycerol to produce TAG (triacylglycerol)

At a pH equal to the isoelectric point (pl) of alanine, the net charge of alanine is zero. Two structures can be drawn that have a net charge of zero, but the predominant form of alanine at its pl is zwitterionic. CH3 H,N CH3 ** H¸N-C H Zwitterionic H Uncharged OH Select statements that explain why alanine is predominantly zwitterionic at its pl. pk of alanine's amino group is more than its pl. pk of alanine's carboxyl group is more than its pl. PK of alanine's carboxyl group is less than its pl. pk of alanine's amino group is less than its pl. Correct Answer What fraction of alanine is in the completely uncharged form at its pl? 1 in 2.2 × 107 1 in 1.6 × 10² 1 in 4680 1 in 9460
How does a voltage-gated sodium channel work? Specifically, how and why does a change in voltage trigger their opening? Please be detailed
When sodium ions enter a neuron during depolarization, they trigger the opening of additional voltage-gated sodium channels nearby, creating a positive feedback loop where the influx of sodium ions further depolarizes the membrane, causing even more sodium channels to open and allowing more sodium ions to enter the cell, thus sustaining the depolarization process until the action potential peaks. But how and why exactly does the influx of sodium ions trigger more sodium channels to let in more sodium? Please explain
