8239996313MonosaccharideA monomer which makes up carbohydrates. Carbohydrates can also be present in this form. These are typically sweet-tasting and used as an immediate energy source for cells Ex: glucose, fructose and galactose.0
8240022386DisaccharideA double sugar, consisting of two monosaccharides joined by dehydration synthesis, forming a glycosidic linkage. These are small enough to be soluble in water and are used as a transport form. Ex: lactose, maltose, sucrose1
8240030540PolysaccharideA polymer of thousands of simple sugars formed by dehydration synthesis. These are used in energy storage, cell structure or in cell recognition Ex: cellulose, glycogen, starch2
8241592217CelluloseA polysaccharide found in plant cell walls It is a linear molecule composed of beta-glucose in a 1,4 arrangement.3
8241609429StarchA polysaccharide used for energy storage in plants It is composed of alpha-glucose in a 1,4 arrangement Exists in two forms4
8241737602Fatty AcidLong hydrocarbon chains found in certain types of lipids (triglycerides and phospholipids) They may differ in length (4-24 carbons typically) and in the number of double bonds5
8241787146Saturated Fatty AcidThis type of fatty acid does not possess any double bonds. Therefore, it has the maximum possible number of Hydrogen atoms. They are linear in structure, originate from animal sources (ex.: fats) and are typically solid at room temperature.6
8241811934Monounsaturated Fatty AcidThis type of fatty acid possesses one double bond It is bent in structure, originates from plant sources (oils) and is typically liquid at room temperature.7
8241848539Polyunsaturated Fatty AcidThis type of fatty acid possess more than one double bond It is bent in structure, originates from plant sources (oils) and is typically liquid at room temperature.8
8241851571Cis (fatty acid)One type of unsaturated fatty acid isomer. The hydrogen atoms attached to the carbon double bond are on the same side9
8241869858Trans (fatty acid)One type of unsaturated fatty acid isomer The hydrogen atoms attached to the carbon double bond are on different sides These do not commonly occur in nature and are typically produced by an industrial process called hydrogenation They are generally linear in structure (despite being unsaturated) and are usually solid at room temperature10
8241907373TriglycerideLargest class of lipids which function primarily as long-term energy storage molecules They are formed when condensation reactions occur between one glycerol and three fatty acids (the condensation reactions created 3 molecules of water) Animals tend to store these as fats (solid), while plants tend to store these as oils (liquid)11
