In both humans and animals, the body fat stores appear as triglycerides, which can be composed of different fatty acids, but they all have about 9 kilocalories per gram (USDA).
There can be different amounts of fat in different fat cells, so there can be slightly different amounts of fat in 100 grams of different types of fat tissue.

The question suggests unfamiliarity with the nature of biochemical oxidations and their relation to energy transfer in biology. The naïve reader is recommended to consult a text for a coverage of this subject: all I feel is appropriate here is a general summary followed by a brief indication of the key reactions.
General principles of energetic ...
This is simplified version of a complex situation, but in summary:
A key role of liver is to control the distribution of metabolic fuel
for the other tissues (it always has enough for its own
The way it behaves differs in the fed and fasted states (because of control by hormones and the concentration of metabolites).
In the fed state (after ...
Here's a study in which they measured a decrease in endogenous cholesterol synthesis after various amounts of dietary cholesterol: Dietary Cholesterol Feeding Suppresses Human Cholesterol Synthesis Measured by Deuterium Incorporation and Urinary Mevalonic Acid Levels (Arteriosclerosis, Thrombosis, and Vascular Biology, 1996):
The objective of this study ...

According to Reverse Cholesterol Transport: Molecular Mechanisms and the Non-medical Approach to Enhance HDL Cholesterol (Frontiers in Physiology, 2018), both HDL and LDL are involved in reverse cholesterol transport.
In short: HDL takes cholesterol from the blood (from lipid-laden macrophages) and delivers it to the liver 1) via scavenger receptors (SR-B1)...
