A sample from this course

One topic, as StudyPath teaches it.

Biochemistry of raw hides and skins

Raw hides and skins are complex biological materials composed mainly of collagen, lipids, and various non‑collagenous proteins. Mastering the biochemical composition and the changes that occur during skinning, tanning, and curing is essential for predicting texture, durability, and suitability for different leather products.
