Re: Enzymes

Ok I now understand what you all have been trying to explain to me for the last 2 days. (By understand I mean understand on a very basic level!) But I have managed to put it into my powerpoint presentation- huzzah! And better, I know what enzymes are for and what saccharides etc are so hopefully I w...

Re: Enzymes

Ahh polypeptides that does actually sort of answer another question I had- are polypeptides broken down into peptides? And then into amino acids? Or are polypeptides and peptides in reality the same thing? Are there 'dipeptides'? Or have I just made that word up? I'm going to be honest, much of that...

Re: Enzymes

So amylase breaks polysaccharides into disaccharides in the mouth. This disaccharide (in the form of maltose) travles through to the small intestine where maltese breaks the disaccharide into monosaccharide (glucose)? Do you know how disaccharides reach the small intestine? I assume it isn't through...

Re: Enzymes

Ok that actually all made sense. I think maybe I am trying to be too reductionist and group it all into an easy to read table consisting of set categories, like enzyme, substrate, result etc when really it doesn't quite work like that. (unfortunately!) Or at least it does but there are so many enzym...

Re: Enzymes

Ah right ok, it's starting to make sense. Ok would I be right in saying that in the stomach, the enzyme Pepsin (belonging to the enzyme group peptidase) breaks down the substrate protein into peptides. These then pass into the duodenum where the peptides now become the substrate? So the amylase tryp...

Re: Enzymes

Swede: pepsin is protease! m Muska: OK, you need to acount, that in the body there is both anabolism (building up) and catabolism (break down). Also, if you want something to break down, you have first to build that, right? So, basically everything can be both substrate as well as product, but of d...

Re:

If you by "pepides" meant "peptides" I think you had better change that to monosaccharides or disaccharides. You could also change the "substrate group"-example to polysaccharides. Pepsin acts on polysacharides to make mainlu disaccharides. Peptides are amino acids bou...

Re: Enzymes

laymans terms- simplified or easier to explain. Ie I don't want to get into too much depth because my understanding is minimal, and I'm not a biology studen but rather a psychology student who has taken an extra biology module to better understand the bodies physiology. I have to give a presentation...

Enzymes

Argh. Firstly apologies if this is in the wrong forum (I usually end up managing to post stuff in the wrong forum, it's not deliberate- honest!) I need help with enzymes. Or rather, I need some sort of enzyme for dummies advice. I understand what enzymes do, and how they break down molecules. After ...
