A saturated fat is a type of fat in which the fatty acid chains have all single bonds between the carbon atoms. A fat known as a glyceride is made of two kinds of smaller molecules: a short glycerol backbone and fatty acids that each contain a long linear or branched chain of carbon (C) atoms.

Saturated fatty acids 16 and 18 carbons in length are the dominant types in the epidermis, [35] [36] while unsaturated fatty acids and saturated fatty acids of various other lengths are also present. [35] [36] The relative abundance of the different fatty acids in the epidermis is dependent on the body site the skin is covering. [36]
It is a major component of palm oil from the fruit of Elaeis guineensis , making up to 44% of total fats. Meats, cheeses, butter, and other dairy products also contain palmitic acid, amounting to 50–60% of total fats. [11] Palmitates are the salts and esters of palmitic acid. The palmitate anion is the observed form of palmitic acid at ...
Pentadecylic acid, also known as pentadecanoic acid or C15:0, is an odd-chain saturated fatty acid. Its molecular formula is CH 3 (CH 2) 13 CO 2 H. It is a colorless solid. A laboratory preparation involves permanganate oxidation of 1-hexadecene (CH 3 (CH 2) 13 CH=CH 2). [2] It is one of the most common odd-chain fatty acids, although it is ...
A young adult human's fat stores average between about 15–20 kg (33–44 lb), but varies greatly depending on age, sex, and individual disposition. [10] In contrast, the human body stores only about 400 g (0.9 lb) of glycogen , of which 300 g (0.7 lb) is locked inside the skeletal muscles and is unavailable to the body as a whole.
Put another way, if the human body relied on carbohydrates to store energy, then a person would need to carry 31 kg (67.5 lb) of hydrated glycogen to have the energy equivalent to 4.6 kg (10 lb) of fat. [10] Hibernating animals provide a good example for utilization of fat reserves as fuel. For example, bears hibernate for about 7 months, and ...
Trans fat has been found to act like saturated in raising the blood level of LDL ("bad cholesterol"); but, unlike saturated fat, it also decreases levels of HDL ("good cholesterol"). The net increase in LDL/HDL ratio with trans fat, a widely accepted indicator of risk for coronary artery disease, is approximately double that due to saturated fat.
