They initially start making less of the proteoglycans and more Type II collagen, but soon switch over to making a different collagen type, type I collagen.

他们最开始形成少量的蛋白聚糖和更多的二型胶原，将很快转向产生另一类胶原：一型胶原。

Potato peels also contain many biofunctional compounds. A 2019 study showed that potato peel extract stimulated the synthesis of type I collagen, an effect that may have anti-aging benefits.

土豆皮还含有许多生物活性成分。2019年的一项研究表明，土豆皮提取物刺激了I型胶原蛋白的合成，可能具有抗衰老的功效。

Unfortunately, type I collagen doesn't interact with the proteoglycans in the same way and there is an overall decrease in elasticity in the cartilage matrix, allowing it to breakdown.

不幸的是，一型胶原并不能和蛋白聚糖正常地相互作用，导致软骨基质整体弹性减弱，容易分解。
