And these are shown on the board. So this is glybular domain g one, glylor domain g two and glybular domain g three. And this entire purple structure is that protein component of the aggregate of the proteoglycan. Now, between g two and g three, we have this long section of amino acids, and it's the sequence of amino acids between the g two and the g three glybular domains of agriculture that basically are able to actually bind two important types of glycose aminoglycans, namely, the conjoitin six sulfate, which is shown in red, and the keratin sulfate, which is shown in brown. So these red projections are conroytin six sulfate, the brown projections are the keratin sulfate and they're bound to the actual sequence of amino acids between the g three and the g two globular domains of agriculture. Now, if we take a look at g one, the g one domain of aggregate is actually bound to this green fiber.
