Testosterone is the primary male sex hormone and an anabolic steroid.
Tetracyclines are broad-spectrum antibiotics whose general usefulness has been reduced with the onset of antibiotic resistance.
Theodore (Nicolas) Gobley, who first isolated, and ultimately determined the chemical structure of lecithin, the first identified and characterized member of the phospholipids class, and a pioneer researcher in the study and analysis of the chemical components of brain tissues, was born in Paris on 11 May 1811 and died in Bagneres-de-Luchon (a small city in central Pyrenees famous in the second half of the 19th century for its thermal waters) on 1 September 1876.

Thromboxane is a member of the family of lipids known as eicosanoids.
Tocopherols (TCP) are a class of organic chemical compounds (more precisely, various methylated phenols), many of which have vitamin E activity.
Trans fat, also called trans-unsaturated fatty acids or trans fatty acids, are a type of unsaturated fat that occur in small amounts in nature but became widely produced industrially from vegetable fats starting in the 1950s for use in margarine, snack food, and packaged baked goods and for frying fast food.
A triglyceride (TG, triacylglycerol, TAG, or triacylglyceride) is an ester derived from glycerol and three fatty acids (from tri- and glyceride).
An unilamellar liposome is a spherical chamber/vesicle, bounded by a single bilayer of an amphiphilic lipid or a mixture of such lipids, containing aqueous solution inside the chamber.
An unsaturated fat is a fat or fatty acid in which there is at least one double bond within the fatty acid chain.
Vegetable oils, or vegetable fats, are fats extracted from seeds, or less often, from other parts of fruits.
In cell biology, a vesicle is a small structure within a cell, or extracellular, consisting of fluid enclosed by a lipid bilayer.
A vitamin is an organic molecule (or related set of molecules) which is an essential micronutrient - that is, a substance which an organism needs in small quantities for the proper functioning of its metabolism - but cannot synthesize it (either at all, or in sufficient quantities), and therefore it must be obtained through the diet.
Vitamin A is a group of unsaturated nutritional organic compounds that includes retinol, retinal, retinoic acid, and several provitamin A carotenoids (most notably beta-carotene).
Vitamin D is a group of fat-soluble secosteroids responsible for increasing intestinal absorption of calcium, magnesium, and phosphate, and multiple other biological effects.
Vitamin E is a group of eight compounds that include four tocopherols and four tocotrienols.
Vitamin K is a group of structurally similar, fat-soluble vitamins that the human body requires for complete synthesis of certain proteins that are prerequisites for blood coagulation (K from Koagulation, Danish for "coagulation") and which the body also needs for controlling binding of calcium in bones and other tissues.
