what is it about niacin that makes it important for extracting energy from foods?
Niacin causes dilation of the small blood vessels in the skin so that more blood can rush through and this require extracting more energy from foods.
what is it about niacin that makes it important for extracting energy from foods?
1. Describe the process of extracting energy from a molecule of glucose in the presence of oxygen via cellular respiration. Make sure to mention where in the cell the reactions involved in extracting energy from glucose are occurring and what the chemical inputs and outputs are for each of those reaction processes.
Why is it important to open the stopcock on the separatory funnel when extracting from one phase (say, organic phase,) into another phase (say, aqueous phase)?
What is it about “tenacity” that makes it such an important characteristic of entrepreneurship? 300 words
Example: pH from Ka The K, for niacin is 1.5 x105. What is the pH of a 0.010 M solution of niacin? Find the percent dissociation.
Review what fermentation is and how it is an important process in the production of foods of microbial origin.
1. Water is an important part of our diet because A. transports energy throughout the body B. Makes me happy in the heart C. Is a main source of energy D Carries waste out of the body 2. Using visual portion guides, an average size fist is equal to what measurement and should be used for which foods a 3 ounces, cooked meat b.1 cup cooked pasta c 3 ounces dried fruit d 1 cup shredded cheese
Example: K, from pH Niacin is one of the B vitamins. A 0.020 M solution of niacin has a pH of 3.26. What is the acid-dissociation constant for niacin? Find the percent dissociation (ionization)
In the acid/base extraction lab, a carboxylic acid was separated
from fluorene by extracting the carboxylic acid into the aqueous
layer using NaOH solution (a review of this experiment before lab
will be helpful). Phenols (aromatic alcohols) can also be separated
using this method. In a mixture of a phenol and a non-reacting
organic compound, the phenol may be selectively removed from an
organic solvent by extracting with a dilute NaOH solution. After
separating the organic and aqueous layers, the...
Post lab question help. This lab was about extracting limonene from
orange peels. Chemical tests were then done with limonene using Br2
and MnO4.
a. A pure sample of (R)-limonene has a specific rotation of +125.6". If a sample had a specific rotation of +80.4º, how much of each enantiomer is present in the sample? Show your work b. Why is a large excess of water used in the distilling flask in the steam distillation of limonene? c. After your...
What is the change in energy ΔEΔEDeltaE of the hydrogen atom as the electron makes the transition from the n=3n=3 energy level to the n=1n=1 energy level? Express your answer numerically in electron volts.
