SIXTEEN FIGUKES
Prominent among the functional implications of alkaline phosphatase, as suggested by numerous chemical and histochcrnical studies rcvicwed by X o o g ( '46), Sols ( '49), and Bradfield ( '51), are its association wiih transport mechanisms, with calcification, and with growth and diff crentiatioii. A correlation between alkaline phosphatase and glycogun is apparent from the studies of Harris ( ' 3 2 ) , Glock ( '40), and Horowitz ('42) which support the view that glycogen is a source for the production of gluco-phosphoric esters from which the enzyme liberates the phosphate ions used in calcification. Other examples of a reciprocal relation between the cnayme and polysaccharide are seen in the observations of Johnson and Bevelander who found alkaline phosphatase and glycogen simultaneously present in developing hairs ( '46) and developing down feathers ( '47).
Caspersson ('47) and Brachck ('47%) callcd attention to a correlation between ribonucleic acid content of a cell and its
