Do you mean “Bone and collagen are made up of type I (collagen)”? If so, yes — here’s a short summary:

- Bone’s organic matrix is primarily type I collagen (it makes up most of the organic portion of bone).
- Bone also contains mineral (hydroxyapatite, Ca10(PO4)6(OH)2) that is deposited on the type I collagen scaffold, plus small amounts of noncollagenous proteins and proteoglycans.
- Type I collagen is also the main collagen in tendon, skin, and dentin. Other collagens: type II predominates in hyaline cartilage; type III in reticular fibers/early wound tissue; type IV in basement membranes, etc.
- Brief biology: type I collagen is a triple helix rich in Gly–X–Y (often proline/hydroxyproline). Its synthesis requires vitamin C (for proline/lysine hydroxylation) and crosslinking for tensile strength.

If you meant something else by “ti,” or want more detail (composition percentages, synthesis pathway, clinical implications), tell me and I’ll expand.
