birthday and your recent doctor’s visit alerted you of the fact you have HTN and are very overweight. In order to keep CVD at bay‚ your doctor recommended the following diet: 20-25 kcal/kg‚ .8 g pro ( or- 15% kcals as pro)‚ 30% kcal from fat ( follow TLC guidelines) and 1500 mg Na. Be sure to eat no less than 35 gm fiber/d. 1. Meal Pattern A. wt: 184# ( 84 kg) Ht: 6’0” (72 in/ 183 cm/ 1.83 m) Age: 22 YOWM Kcal: 25 kcal/kg x 72 kg = 1900 kcals 655 + (9.6x 72) + (1.8 x 183cm)

Thin layer chromatography (TLC) is a technique employed in chemistry laboratories intended to analyze the progress of a chemical reaction in a visual sense. The chemical characteristics of the components present in this method allow for comparison (separation) of different chemical compounds by polarity. The silica gel TLC plate is polar in nature (a form of silicon dioxide)‚ meaning that when a compound or liquid sample is spotted on the bottom of the plate (origin) for it to be analyzed‚ the polarity

Client Report 1 5/29/15 Clients: T.J. Maxx and Burlington Coat Factory Social Media and PR This week‚ I looked at the social media activity of T.J. Maxx and Burlington Coat Factory on Instagram‚ Twitter‚ and Facebook. In terms of Instagram‚ T.J. Maxx seemed to focus on spring fashions and trends this week. The pictures they used were sent to them by followers‚ whom they tagged and acknowledged in their posts. I thought this was a smart business strategy‚ because not only were they showcasing their

them to improve the amount of numbers they were able to recall. Many researchers have suggested that ingesting dark chocolate at least once a week will improve memory because of the high amounts of flavonoids in dark chocolate. Many studies suggest that eating chocolate and other foods high in flavonoids will improve memory in the elderly and also protect the brain from normal memory loss due to age (Russell‚ February 2016). Despite the general assumption that chocolate improves memory‚ six of the

Stock solutions of the test compounds were prepared in the carrier solvents. Further dilution was done in emulsified water by maintaining emulsifier (Tween – 80) level at 0.5 % to yield various concentrations. Castor leaf discs (4 cm diameter) were punched out from the washed and dried castor leaves. Leaf discs were dipped

concentrate (C1)‚ however concentrate 1 did not create a visible spot on the TLC plate‚ so it is unclear whether or not carotenoids were present in concentrate 1. However‚ since concentrate 2 (C2) yielded 2 spots on the TLC plate‚ it is possible one of these spots was a carotenoid. In particular‚ spot 2 has the largest Rf value‚ indicating it was the least polar compound because it had the largest A value‚ traveling the farthest up the TLC plate with the non-polar developing solvent. It can be hypothesized

Stereochemistry of Dihydroxylation Reactions Question: Can the stereochemical outcome of dihydroxylation reactions be determined by thin layer chromatography? Overview: In this experiment‚ you will perform two reactions that transform alkenes into diols. While similar in functional group transformation‚ these reactions may lead to stereochemically different products. The two possible products are diastereomers of one another‚ and therefore have different physical chracteristics. After

To do this you will first extract carotenoid pigments from the paste and then use column chromatography to isolate the lycopene from the other pigments. You will then use TLC to evaluate the column chromatography separation. Note: because lycopene is light-sensitive‚ prevent any unnecessary exposure to light. Procedure: Weigh roughly 1.0 g of tomato paste into a 15 mL centrifuge tube. Add 4 mL of a 50/50 (% volume)
