How can I carry DC component to negative side?
How can I carry it to negative side?

Assuming that you mean 'How can I add a negative offset to the sine wave', this is my solution:

The 100n capacitor is use for DC blocking and the two 10k resistors are used to bias the signal to -2.5V, so it will swing around that point. You can change the DC offset by changing the resistor values.
