In lipid polymorphism, if the packing ratio [clarification needed] of lipids is greater or less than one, lipid membranes can form two separate hexagonal phases, or nonlamellar phases, in which long, tubular aggregates form according to the environment in which the lipid is introduced.
The second step in lipid metabolism is absorption of fats. Short chain fatty acids can be absorbed in the stomach, while most absorption of fats occurs only in the small intestines. Once the triglycerides are broken down into individual fatty acids and glycerols, along with cholesterol, they will aggregate into structures called micelles. Fatty ...
The fatty acid structure is one of the most fundamental categories of biological lipids and is commonly used as a building-block of more structurally complex lipids. The carbon chain, typically between four and 24 carbons long, [ 23 ] may be saturated or unsaturated , and may be attached to functional groups containing oxygen , halogens ...
Phospholipids [1] are a class of lipids whose molecule has a hydrophilic "head" containing a phosphate group and two hydrophobic "tails" derived from fatty acids, joined by an alcohol residue (usually a glycerol molecule). Marine phospholipids typically have omega-3 fatty acids EPA and DHA integrated as part of the phospholipid molecule. [2]
The value of the equilibrium constant determine the following: 1) if monomers are mixed ideally (K = 4.0) 2) when the monomers are mixed homogenously also referred to as a homo-association (K < 4.0) and 3) if the monomers have interchanged heterogeneously which is referred to as an hetero-association (K > 4.0) A plot of (K) is then created ...
The structure of simple macromolecules, such as homopolymers, may be described in terms of the individual monomer subunit and total molecular mass. Complicated biomacromolecules, on the other hand, require multi-faceted structural description such as the hierarchy of structures used to describe proteins.
The surface of a curved lipid bilayer. Lipidology is the scientific study of lipids. Lipids are a group of biological macromolecules that have a multitude of functions in the body. [1] [2] [3] Clinical studies on lipid metabolism in the body have led to developments in therapeutic lipidology for disorders such as cardiovascular disease. [4]
These structures vary in their fatty acid alkyl groups as they can contain different carbon numbers, different degrees of unsaturation, and different configurations and positions of olefins.
