what are N-Cadhering and Cadherin 9 ?
What they have in common and where is most expressed in the mouse brain.

Solutions

Expert Solution

Cadherins (Calcium-dependent ones) are a type of cell adhesion molecules (CAM) that mainly function in the formation of adherens junction to bind cells.

Cadherins are usually named according to their tissue distribution in the body. N-cadherins are named so because they are mostly distributed in neurons.

Cadherin 9 is a type II classical cadherin. It is an integral membrane protein and it mediates calcium-dependent cell-cell adhesion.

Gene expression profiles indicate that Cadherin 9 expression is important for synaptogenic specificity. Cadherin 9 expression is high in neurons of brain, and its downregulation can lead to a selective decrease in the size and number of hippocampal dentate gyrus (DG) neurons.

The most common experimental technique to perform elemental analysis is combustion analysis, where a sample is burned in a large excess of oxygen and the combustion products are trapped in a variety of ways. A 99.99% pure, 0.4831 g sample containing only carbon, hydrogen, and nitrogen is subjected to combustion analysis, resulting in the formation of 1.353 g CO2, 0.2750 g H2O, and 0.1833 g NO. What is the empirical formula of the sample?
