What is the shape for lipids?
… a lipid molecule has a head group that is roughly equal to the size of the tail it gives it a “cylindrical” shape ( fig 2A). As a consequence of this physical property, these lipids tend to form a bilayer, i.e. two leaflets of lipid molecules arranged in long sheet-like structures ( fig 2B).
What macromolecule is glycogen?
Carbohydrates
Comparing the Biological Macromolecules
| Macromolecule | Basic Formula, key features | Examples |
|---|---|---|
| Lipids | C:H:O Greater than 2:1 H:O (carboxyl group) | Butter, oil, cholesterol, beeswax |
| Carbohydrates | C:H:O 1:2:1 | Glucose, Fructose, Starch, Glycogen, Cellulose |
| Nucleic Acids | CHONP pentose, nitrogenous base, phosphate | DNA, RNA |
What macromolecule is triglyceride?
Lipids
In Summary: Lipids Lipids are a class of macromolecules that are nonpolar and hydrophobic in nature. Major types include fats and oils, waxes, phospholipids, and steroids. Fats are a stored form of energy and are also known as triacylglycerols or triglycerides.
What macromolecule is polypeptide?
Proteins
Polypeptide chains are strings of amino acids, joined by peptide bonds. Proteins are formed by twisting up one or more poly peptide chains. It is the shape, or conformation, of the protein that gives it its properties. There are four levels of protein structure.
What macromolecule is amylose?
starch
Amylose is a polysaccharide made of α-D-glucose units, bonded to each other through α(1→4) glycosidic bonds. It is one of the two components of starch, making up approximately 20-30%.
What is an example common name of lipids?
Lipids are molecules that contain hydrocarbons and make up the building blocks of the structure and function of living cells. Examples of lipids include fats, oils, waxes, certain vitamins (such as A, D, E and K), hormones and most of the cell membrane that is not made up of protein.
Are polypeptides a lipid?
Peptide bond is present in proteins, not in lipids or nucleic acids.
What is the name of the polymer of lipids?
triglycerides
Lipids – polymers called diglycerides, triglycerides; monomers are glycerol and fatty acids. Proteins – polymers are known as polypeptides; monomers are amino acids.
What are the 4 main types of lipids?
The four main groups of lipids include:
- Fatty acids (saturated and unsaturated)
- Glycerides (glycerol-containing lipids)
- Nonglyceride lipids (sphingolipids, steroids, waxes)
- Complex lipids (lipoproteins, glycolipids)
