Which articles from the un convention on the rights of the child relate to child protection?

i need to do an assignment based on this, i have researched so much through the articles but can not decide which ones they are. this is mainly because some internet websites have highlighted fewer articles than i did, therefore leaving me confused! i know for definite that they are stated in part 1 and range from articles 1 - 41 but im struggling to identify which ones actually are related to child protection, can anyone please help me on this?
