Gelatin or poly-L-tyrosyl gelatin shows extensive degradation when exposed to ultraviolet radiation at a wavelength of 230 nm. Bovine serum albumin, a globular protein, exposed either to such ultraviolet radiation or to gamma-irradiation in the solid state resists the photolysis of peptide bonds. Molecular weights are determined by the ultracentrifugal "low speed" sedimentation equilibrium method. The effect of different speeds on the apparent average molecular weight of heterogenous material is clearly illustrated.
明胶或聚-L-酪氨酰明胶在波长为230nm的紫外线照射下会发生广泛降解。球状蛋白牛血清白蛋白，无论是在固态下受到这种紫外线照射还是γ射线照射，都能抵抗肽键的光解。分子量通过超速离心“低速”沉降平衡法测定。不同速度对异质材料表观平均分子量的影响得到了清晰的说明。
