Now, for instance, if we eat a piece of chicken, that chicken not only has protein and fat, it also contains polysaccharides carbohydrates store in a form we call glycogen, which is the same form that we mentioned just a moment ago. Now, if we ingest things like pasta or bread or cereal, these are actually polysaccharides that come from plants. And so what we're ingesting is starch. And there are two types of starch. So we have amylose and amylopectin. So one of them is basically a linear helical structure that's the amylose.
