Productomschrijving


In de natuur komen ongeveer vijfhonderd aminozuren voor. Twintig hiervan zijn aminozuren die als bouwstenen dienen voor eiwitten in het menselijk lichaam, deze worden aangeduid met de term ‘fundamentele aminozuren’. Deze fundamentele aminozuren kunnen weer onderverdeeld worden in de categorieën ‘essentieel’, ‘semi-essentieel’ en ‘niet-essentieel’. L-tryptofaan hoort bij de zogenaamde essentiële aminozuren, wat wil zeggen dat het lichaam deze niet zelf kan aanmaken uit andere aminozuren, en dat men om te kunnen voorzien in de dagelijkse behoefte volledig afhankelijk is van de voeding.

Tryptofaan komt in voeding in te kleine hoeveelheden voor om dit als bron te kunnen gebruiken voor de productie van supplementen. Tryptofaan voor gebruik in een supplement wordt daarom doorgaans vervaardigd door middel van een speciaal ontwikkeld fermentatieproces. Micro-organismen kunnen namelijk wél zelf tryptofaan synthetiseren, en van deze eigenschap wordt bij dit proces gebruikgemaakt. Hierbij wordt de natuurlijke L-vorm van tryptofaan aangemaakt. De synthetische D-vorm is niet werkzaam en kan de biologische beschikbaarheid van de natuurlijke L-vorm verminderen. Suppletie met D-tryptofaan wordt daarom afgeraden.

Tryptofaan is onder andere de voorloperstof van niacine (vitamine B3), 5-HTP (5-hydroxytryptofaan), de neurotransmitter serotonine en het hormoon melatonine. Het kan de bloed-hersenbarrière passeren, maar is hierbij gevoelig voor concurrentie met andere aminozuren. Een tryptofaansupplement moet daarom bij voorkeur op een nuchtere maag, los van andere aminozuren, ingenomen worden.

Reasonably adequate room divider
Size: 4 Panel-88'', Color: Beige
I'm reviewing this as I assemble it. Couple things: 1. I didn't expect as much assembly. I've ordered dividers before and they more-or-less came as one unit. Sometimes the panels needed screwing together. These require complete assembly and come largely as three rods: two make up vertical columns and snap together. Another one (called part "C") makes the horizontal columns and you have two of these per panel (one attaches to part "A" and the other part "B"). These parts are metal with a plastic shim. Using the wood screws to attach to part "C" is a real pain in the neck. There's not much holding the panel in place so it's a little tricky. One tactic I've found while I'm assembling that works for the initial connections from parts A and B to their respective "C" rods is to hold the screw in place with a screw driver and then rotating the rod around the screw. This will do a number on your hands if you aren't wearing gloves. This obviously doesn't work when completing the connection. Using a driller driver on this is really near impossible because there isn't anything you can use to secure it in place. You can use it on the first panel, but as it gets longer, it becomes increasingly difficult and because it isn't wood, it's really tight. I considered drilling larger pilot holes but since there are only 4x4=16 screws I need to screw in, I just decided to use my screw driver to complete it. 2. Also related to assembly. When completing the panels (attaching parts "A" and "B" to parts "C" that have the cloth cover on it), you have to be careful that when you tighten that side that it isn't loosening the other side. Because the pilot holes are so tight, you can end up rotating the rod, which rotates it in the same direction as looser on the original side. Having someone hold the "C" rod in place while you screw it in is probably the easiest approach. I didn't have a 2nd person, so I just had to keep flipping back and forth and tightening both sides as I screwed it in. Not the worlds biggest deal, but annoying nonetheless. 3. The way the instructions are written, they seem to suggest building this thing progressively; that is, you do panel 1, then 2, connect them together, then do 3 and connect it, etc. I took a different route that I suspect saved me quite a bit of trouble, and I assembled all four panels first and THEN connected everything together. 4. For the love of God make sure you check that the plastic tip is on the same side for every panel. Otherwise, you have to take one side apart again and reverse it. On the bright side, if this happens, you've essentially bored out the pilot holes to be the correct size... which is having me question if I shouldn't have just bored them out to the appropriate width in the first place. 5. Attaching all of the panels together is also an enormous pain in the ass unless you happen to have an 88" long elevated surface. Attaching the legs either requires you to elevate one side, which will invariably twist the inexplicably cheap material in the bottom connectors... or you can attach them sideways... or you can put this thing upright, having two people hold the panels in place while you use the allen wrench to tighten the bolts on the underside. None of those are particularly great options. NOW on to the utility itself. 1. The panels do let some light through (I didn't believe their advertising, and that was one of the reasons that I bought beige, is that I wanted it to not be too dark). They aren't transparent though, so it isn't that far off from their description. They functionally work great, and keep the mess of wires hidden and when I'm sitting at my desk, actually reflect quite a bit of light into my office. Great! 2. My wife has described these as "the most hideous piece of furniture ever conceived of by man." So it does not have spouse approval factor. Granted, she will seldom be in my office area, so that isn't the end of the world. 3. These are really hard to align in a way that doesn't look a little tacky. There are some plastic connectors but they don't do a bang up job of keeping these in place. Each panel is slightly tilted and it's... quite obvious. I may at some point make my own improvements to these to help make them more level. It's not a particularly expensive product so I wasn't expecting much so it's fine and I'm not going to ding them on the rating because of it. All said, would I buy this product again? Probably not. It's assembly was ~90 minutes which is about 75 minutes longer than I was anticipating spending on this (not including the 5 minute writeup that I'm doing here). But am I going to return it? Also no, if for no other reason I'd be just as annoyed taking it apart and putting it in the original box to return it.

Quick and pretty privacy screen
Color: Beige, Size: 4 Panel-67”
Relatively easy to assemble. Looks very nice at the nursing home of my friend and is sturdy. Unfortunately, aides place towels and sometimes clothes over it and it stands stable. The bamboo color is nice to look at. It is lightweight and can be moved easily!

Esthetically sound, materially flimsy
Color: Beige, Size: 4 Panel-67”
The item at first seemed okay and quality was good. But it’s a little flimsy and tips over frequently. I’m thinking of returning and replacing pretty soon.
