Lipids Lipid is the collective name for fats, oils, waxes and fat-like molecules (such as steroids) found in the body. protection, waterproofing, insulation and buoyancy agents. The basic unit of lipids is a triglyceride, synthesised from glycerol (propane-1,2,3-triol) and fatty acids. Glycerol is a type of alcohol. Alcohols are organic compounds. Their molecules are characterised by hydroxyl groups, -OH. Glycerol is a trihydric alcohol, which means each molecule has three hydroxyl groups.

Functional Groups and Biomolecules Alcohols are biomolecules that contain at least one hydroxyl group (R―OH). The simplest of all oxygen-containing functional groups, hydroxyl groups add polarity to organic molecules because of the strong electronegative nature of oxygen atoms.Therefore, unless the remainder of an organic molecule is very large and nonpolar, most alcohols dissolve in water by forming hydrogen bonds.lthough it may be confusing, carbonyl and carboxyl functional groups (R―COOH) have similar names for a reason. A carboxyl group contains both a carbonyl group and a hydroxyl group, bonded to the same carbon atom. The name carboxyl derives from combining these two terms, carbonyl + hydroxyl = carboxyl.

- 1 Phospholipids consist of a glycerol molecule, two fatty acids, and a phosphate group that is modified by an alcohol. 2  The phosphate group is the negatively-charged polar head, which is hydrophilic.  The fatty acid chains are the uncharged, nonpolar tails, which are hydrophobic.

- Naturally occurring fats and oils are Triglycerides. Triglycerides consist of three fatty acids bound to a Glycerol backbone. Each fatty acid consists of a Carbon-Hydrogen chain with a Carboxyl group at the end that is attached to the Glycerol molecule.

Elements & Macromolecules in Organisms The fatty acid chains may be saturated (only single bonds between carbons) or unsaturated (contain at least one double bond). A carboxyl functional group (-COOH) is found on the end of the fatty acid that does NOT attach to glycerol. CIRCLE AND LABEL the carboxyl groups in the 2 fatty acids on this worksheet. Color the fatty acid chains the same colors for carbon, hydrogen, and oxygen as you did before.

- A glycerol molecule can have up to three fatty acids attached, and the glycerol molecule of triglycerides contains the maximum of three fatty acids. Since fatty acids are hydrophobic -- water-hating -- molecules, triglycerides cannot dissolve in water.

Structural Biochemistry/Organic Chemistry/Lipids They are phospholipids, glycolipids, and cholesterol. [Structural Biochemistry]. Fats Fats consists of glycerol and 3 fatty acids. Fats are created via 3 condensation reactions creating ester linkages that link the fatty acid carboxyl groups to the hydroxyl groups in glycerol. There are two different types of fatty acids, saturated and unsaturated.

Explain the composition of triglyceride? Answers. Best Answer: A triglyceride (triacylglycerol, TAG, or triacylglyceride) is an ester derived from glycerol and three fatty acids. Triglycerides are formed by combining glycerol with three molecules of fatty acid. The glycerol molecule has three hydroxyl (HO-) groups. Each fatty acid has a carboxyl group (COOH). In triglycerides, the hydroxyl groups of the glycerol join the carboxyl groups of the fatty acid to form ester bonds[ see the site for more. Source(s): http://en.wikipedia.org/wiki/Triglycerid...

Lipid The word triacylglycerol is sometimes used synonymously with triglyceride. In these compounds, the three hydroxyl groups of glycerol are each esterified, typically by different fatty acids. Because they function as an energy store, these lipids comprise the bulk of storage fat in animal tissues.The hydrolysis of the ester bonds of triglycerides and the release of glycerol and fatty acids from adipose tissue are the initial steps in metabolizing fat.terol lipids, such as cholesterol and its derivatives, are an important component of membrane lipids, along with the glycerophospholipids and sphingomyelins. The steroids, all derived from the same fused four-ring core structure, have different biological roles as hormones and signaling molecules.

Lipids A fat molecule consists of two main components: glycerol and fatty acids. Glycerol is an alcohol with three carbons, five hydrogens, and three hydroxyl (OH) groups. Fatty acids have a long chain of hydrocarbons with a carboxyl group attached and may have 4-36 carbons; however, most of them have 12-18.

Phospholipids, Cholesterol Phospholipids. Phospholipids are abundant in membranes and form the framework in which the other components of the membrane are embedded. Refer to the figure to the right.At the center of a phospholipid lies glycerol, which is a small three carbon molecule. A fatty acid is bonded to each of two carbons of the glycerol molecule.holesterol. Cholesterol is a lipid molecule comprised almost entirely of carbons and hydrogens. At one end is a single oxygen molecule, which is part of a hydroxyl group. Cholesterol is most abundant in plasma membranes, and influences the physical properties of the membrane.

- The most efficient of these is pump speed con-. trol. When a pump’s speed is reduced, less energy is imparted to the fluid and less. energy needs to be throttled or bypassed. Speed can be controlled in a number of. ways, with the most popular type of variable speed drive (VSD) being the variable. frequency drive (VFD). Pump speed adjustment is not appropriate for all pumping systems, however.

- A fat molecule is made up of two components: R is the fatty acid chain. It depends on the fatty acid. Each glycerol binds with three fatty acids molecules and form a triglyceride. There are several types of fatty acids, and fats are usually made up of a mixture of different types. Site hébergé par MaVille-Online.

- In amylopectin there are two types of glycosidic bonds: 1,4 and 1,6. The 1,4 links are the same as in amylose. In addition some glucose molecules have a glycosidic link from carbon atom number 6 to carbon atom number 1 in a new glucose molecule. This produces a branch point in the amylopectin molecule.oth, cellulose and starch, has a linear structure of glucose monomers connected by glyosidic bonds (1-4 glycosidic bond = Carbon atom number 1 linked with Carbon atom number … 4 of the next glucose monomer's). The basic structural difference is whether the linkage is alpha or beta glycosidic bond.
