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. Calories in 100 g of ...

I know that so much fats running in the bloodstream could deposit in arteries, harden forming a plaque and cause atherosclerosis. But what about veins (which are formed from same types of layers as arteries) and capillaries? Wikipedia says this: Veins do not develop atheromata, because they are not subjected to the same haemodynamic pressure that ...

Chance should always be high on our list of explanations of why the history of life turned out in some specific way. As James A. Coffman has described, there are a couple of different notions of chance. Evolutionary biochemistry is quite difficult because today's diversity of biochemical genotypes and phenotypes are a biased representation of the ancient ...

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 requirements). 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 ...

A rough answer to a rough question According to a study conducted in the 1960s, human adipose tissue, on average, contained (per 100g wet weight) 87g fat, 2g protein, 2g sodium and potassium and 10g water. (Nothing else was measured.) This suggests that approx. 3% of adipose tissue is solids other than triglyceride. The figure quoted is presumably the ...

Indeed, lipid fecal loss remains below 5% (w/w) even in situation of high fat supply in healthy humans, [30]. All about those guts and bowls folks! Niot, I., Poirier, H., Tran, T. T. T., & Besnard, P. (2009). Intestinal absorption of long-chain fatty acids: Evidence and uncertainties. Progress in Lipid Research, 48(2), 101–115. doi:10.1016/j.plipres....
