Prototype Class to jquery


Hi,
I'am novice in Jquery.
I would like to make like in prototype to create a class :
Sample.Portal = Class.create();
Sample.Portail.prototype = {
initialize: function(options) {
....
    },
    load: function() {
}
}
var portal = new Sample.Portal();
How i can do that with jQuery ?
Thx
