Glucose forms a single-ring structure known as a pyranose, while fructose forms a five-membered ring structure known as a furanose. Both molecules are monosaccharides and are important components in the structure of larger carbohydrates.
Fischer projections and Haworth projections are used to show the structures of sugars. The Haworth looks a little 3D but the position of the substituents is directly above or below the ring. Hydrogen is omitted. The Fischer looks a bit like a herring bone- which is how I remembered it- ( Fischer-herringbone ?) Best for linear monosaccharides. It shows hydrogens unlike Haworth. One convention is for D and L forms. Best to look at pictures. Wikipedia shows reasonable pictures but detail is good at vanderbilt link
Monosaccharides primarily exist in cyclic forms, which are known as ring conformations. The two most common forms are the pyranose (six-membered ring) and furanose (five-membered ring) structures. In pyranose forms, the anomeric carbon can adopt either the alpha or beta configuration, depending on the orientation of the hydroxyl group relative to the CH2OH group. These ring forms can also exhibit different chair or boat conformations, influencing their stability and reactivity.
These are ribose sugars. In DNA, there are deoxyribose sugars. In ribose sugar (pyranose or furanose), we can see H and OH bond to the second carbon other than two carbon bonds.
A pseudopod is a temporary cytoplasmic projection used by cells such as amoebas for feeding and movement. It forms through the extension and retraction of the cell's cytoplasm, allowing the cell to engulf food particles or move in a particular direction.

1.when the cyclic sturcture of glucose(hexose) is six-membered ring resembling the pyran ring, thus they are called pyranosewhile when hexoses are found in five-membered ring resembling furan ring, thus they are called furanose2.in aldohexose:The interaction between c=o and the secondary OH is found at c5 if it was pyranosethe interaction between c=o and the secondary OH is found at c4 if it was furanosein ketohexose:the interaction between c=o and the secondary OH is found at c6 if it was pyranosethe interaction between c=o and the secondary OH is found at c5 if it was furanose

Denial is the act of asserting that a particluar allegation or fact is not true. There are three different forms or types of denial, including: projection, simple denial, and minimisation.

The perpendicular plate, which forms the superior part of the septum, descends from the cribiform plate of the ethmoid bone.

The acromion process of the scapula can be palpated at the tip of the shoulder. It is a bony projection that forms the highest point of the shoulder and is easily felt just above the shoulder joint.

The kinetoscope was invented by Thomas Edison and his team as a way to create a device that could show short films individually to viewers. It was a precursor to modern motion picture technology and was one of the earliest forms of film projection for entertainment purposes.
The framework of the outer ear is formed by three main structures: the helix, the antihelix, and the tragus. The helix is the curved rim that surrounds the ear, the antihelix is the ridge located inside the helix, and the tragus is the small cartilaginous projection in front of the ear canal.
