Cholesterol
Cholesterol is a sterol (a combination steroid and alcohol) and a lipid found in the cell membranes of all body tissues and transported in the blood plasma of all animals. The name originates from the Greek chole- (bile) and stereos (solid), and the chemical suffix -ol for an alcohol. This is because researchers first identified cholesterol in solid form in gallstones in 1784. In the body, cholesterol can exist in either the free form or as an ester with a single fatty acid (of 10-20 carbons in length) covalently attached to the hydroxyl group at position 3 of the cholesterol ring. Due to the mechanism of synthesis, plasma cholesterol esters tend to contain relatively high proportions of polyunsaturated fatty acids. Most of the cholesterol consumed as a dietary lipid exists as cholesterol esters. Cholesterol esters have a lower solubility in water than cholesterol and are more hydrophobic. They are hydrolyzed by the pancreatic enzyme cholesterol esterase to produce cholesterol and free fatty acids. Cholesterol has vital structural roles in membranes and in lipid metabolism in general. It is a biosynthetic precursor of bile acids, vitamin D, and steroid hormones (glucocorticoids, estrogens, progesterones, androgens and aldosterone). In addition, it contributes to the development and functioning of the central nervous system, and it has major functions in signal transduction and sperm development. Cholesterol is a ubiquitous component of all animal tissues where much of it is located in the membranes, although it is not evenly distributed. The highest proportion of unesterified cholesterol is in the plasma membrane (roughly 30-50\\\\% of the lipid in the membrane or 60-80\\\\% of the cholesterol in the cell), while mitochondria and the endoplasmic reticulum have very low cholesterol contents. Cholesterol is also enriched in early and recycling endosomes, but not in late endosomes. The brain contains more cholesterol than any other organ where it comprises roughly a quarter of the total free cholesterol in the human body. Of all the organic constituents of blood, only glucose is present in a higher molar concentration than cholesterol. Cholesterol esters appear to be the preferred form for transport in plasma and as a biologically inert storage (de-toxified) form. They do not contribute to membranes but are packed into intracellular lipid particles. Cholesterol molecules (i.e. cholesterol esters) are transported throughout the body via lipoprotein particles. The largest lipoproteins, which primarily transport fats from the intestinal mucosa to the liver, are called chylomicrons. They carry mostly triglyceride fats and cholesterol that are from food, especially internal cholesterol secreted by the liver into the bile. In the liver, chylomicron particles give up triglycerides and some cholesterol. They are then converted into low-density lipoprotein (LDL) particles, which carry triglycerides and cholesterol on to other body cells. In healthy individuals, the LDL particles are large and relatively few in number. In contrast, large numbers of small LDL particles are strongly associated with promoting atheromatous disease within the arteries. (Lack of information on LDL particle number and size is one of the major problems of conventional lipid tests.). In conditions with elevated concentrations of oxidized LDL particles, especially small LDL particles, cholesterol promotes atheroma plaque deposits in the walls of arteries, a condition known as atherosclerosis, which is a major contributor to coronary heart disease and other forms of cardiovascular disease. There is a worldwide trend to believe that lower total cholesterol levels tend to correlate with lower atherosclerosis event rates (though some studies refute this idea). As a result, cholesterol has become a very large focus for the scientific community trying to determine the proper amount of cholesterol needed in a healthy diet.

Brassicasterol
Brassicasterol belongs to the class of organic compounds known as ergosterols and derivatives. These are steroids containing ergosta-5,7,22-trien-3beta-ol or a derivative thereof, which is based on the 3beta-hydroxylated ergostane skeleton. Thus, brassicasterol is considered to be a sterol lipid molecule. Brassicasterol is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Brassicasterol is a potential CSF biomarker for Alzheimer’s disease (PMID: 21585343).

Heptanal
Heptanal, also known as enanthal or N-heptaldehyde, belongs to the class of organic compounds known as medium-chain aldehydes. These are an aldehyde with a chain length containing between 6 and 12 carbon atoms. Thus, heptanal is considered to be a fatty aldehyde lipid molecule. It is a colourless liquid with a strong fruity odor, which is used as precursor to components in perfumes and lubricants. Heptanal is a very hydrophobic molecule, practically insoluble in water, and relatively neutral. Heptanal exists in all eukaryotes, ranging from yeast to humans. Heptanal is an aldehydic, citrus, and fat tasting compound. heptanal is found, on average, in the highest concentration in a few different foods, such as corns, tea, and sweet oranges and in a lower concentration in lemons, wild carrots, and carrots. heptanal has also been detected, but not quantified, in several different foods, such as horned melons, common beets, dills, red bell peppers, and malus (crab apple). This could make heptanal a potential biomarker for the consumption of these foods. The formation of heptanal in the fractional distillation of castor oil was already described in 1878. The large-scale production is based on the pyrolytic cleavage of ricinoleic acid ester (Arkema method) and on the hydroformylation of 1-hexene with rhodium 2-ethylhexanoate as a catalyst upon addition of some 2-ethylhexanoic acid (Oxea method):Heptanal naturally occurs in the essential oils of ylang-ylang (Cananga odorata), clary sage (Salvia sclarea), lemon (Citrus x limon), bitter orange (Citrus x aurantium), rose (Rosa) and hyacinth (Hyacinthus). Heptanal is a potentially toxic compound. Heptanal has been found to be associated with several diseases such as ulcerative colitis, crohns disease, uremia, and nonalcoholic fatty liver disease; also heptanal has been linked to the inborn metabolic disorders including celiac disease. The compound has a flash point of 39.5 °C. The explosion range is between 1.1\\% by volume as the lower explosion limit (LEL) and 5.2\\% by volume as the upper explosion limit. Heptanal or heptanaldehyde is an alkyl aldehyde. Full hydrogenation provides the branched primary alcohol 2-pentylnonan-1-ol, also accessible from the Guerbet reaction from heptanol. A by-product of the given reaction is the unpleasant rancid smelling (Z)-2-pentyl-2-nonenal. Heptanal forms flammable vapor-air mixtures. Heptanal is a flammable, slightly volatile colorless liquid of pervasive fruity to oily-greasy odor, which is miscible with alcohols and practically insoluble in water. Heptanal reacts with benzaldehyde in a Knoevenagel reaction under basic catalysis with high yield and selectivity (> 90\\%) to alpha-pentylcinnamaldehyde (also called jasmine aldehyde because of the typical jasmine odor), which is mostly used in many fragrances as a cis/trans isomer mixture. Found in essential oils of ylang-ylang, clary sage, California orange, bitter orange and others. Flavouring agent
