Fat
Fats consist of a wide group of compounds that are generally soluble in organic solvents and generally insoluble in water. Chemically, fats are triglycerides, triesters of glycerol and any of several fatty acids. Fats may be either solid or liquid at room temperature, depending on their structure and composition. Although the words "oils", "fats", and "lipids" are all used to refer to fats, "oils" is usually used to refer to fats that are liquids at normal room temperature, while "fats" is usually used to refer to fats that are solids at normal room temperature. "Lipids" is used to refer to both liquid and solid fats, along with other related substances, usually in a medical or biochemical context. The word "oil" is also used for any substance that does not mix with water and has a greasy feel, such as petroleum (or crude oil), heating oil, and essential oils, regardless of its chemical structure.

Famous quotes containing the word fat:
“O fat white woman whom nobody loves,
Why do you walk through the fields in gloves,
When the grass is soft as the breast of doves
And shivering-sweet to the touch?”

That we insensately forbore to fleece.
On this we blame our last
Threadbare perspectives, seasonal decrease.”

On a white heal-all, holding up a moth
Like a white piece of rigid satin cloth—
Assorted characters of death and blight”
