what is lipid and all its types, bonds and structure ?

Question

Any one can help me. explain for me how it works; which kind of bond and everything ?
thanks 4 ur helping

and if thr is any good web site which i can start with

Answer 1

Lipids are a class of hydrocarbon-containing organic compounds. Lipids are categorized by the fact that they are soluble in nonpolar solvents (such as ether and chloroform) and are relatively insoluble in water. Lipid molecules have these properties because they consist largely of long hydrocarbon tails which are hydrophobic in nature. In living organisms, lipids are used for energy storage, serve as structural components of cell membranes, and constitute important signaling molecules.
Chemically, fatty acids can be described as long-chain monocarboxylic acids and have a general structure of CH3(CH2)nCOOH. The length of the chain usually ranges from 12 to 24, always with an even number of carbons. When the carbon chain contains no double bonds, it is called saturated. If it contains one or more such bonds, it is unsaturated. The presence of double bonds generally reduces the melting point of fatty acids. Furthermore, unsaturated fatty acids can occur either in cis or trans geometric isomers. In most naturally occurring fatty acids, the double bonds are in the cis configuration.

Glycerides are lipids possessing a glycerol (propan-1, 2, 3-triol) core structure with one or more fatty acyl groups, which are fatty acid-derived chains attached to the glycerol backbone by ester linkages. Glycerides with three acyl groups (triglycerides or neutral fats) are the main storage form of fat in animals and plants.

Answer 2

It is well explicated in my link

Lipids are organic compounds with a large hydrocarbone chain and a Polar group as OH

The hydrocarbon chain is not soluble in water but the polar group is

So, liids can be fixed at the interface of liquid (water solvent) and membranes since the polar end is soluble

Answer 3

fat basically... you can have low density lipidproteins LDL and HDL
