Abstract
Summary
The collagen and hexosamine contents of the femurs of growing rats were determined. Regression equations were derived upon the basis that there is a linear relationship between the logarithm of body weight and of femur length and the logarithm of the quantity of collagen and hexosamine. Rate of collagen deposition decreases somewhat as the animal grows. Rate of deposition of hexosamine-containing material, decreases markedly so that the ratio of hexosamine to collagen decreases with growth.
