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 20–25% of it. Because of its tightly packed helical structure, amylose is more resistant to digestion than other starch molecules and is therefore an important ...
The amylose/amylopectin ratio, molecular weight and molecular fine structure influences the physicochemical properties as well as energy release of different types of starches, [28] which affects the number of calories people consume from food. Amylopectin is also sometimes used as a workout supplement due to this caloric density and a ...
A coiled coil is a structural motif in proteins in which 2–7 [1] alpha-helices are coiled together like the strands of a rope. ( Dimers and trimers are the most common types.) They have been found in roughly 5-10% of proteins and have a variety of functions. [ 2 ]
Coiled-coil research began in 1953 when Dr. Francis Crick first reported on the theory behind the packing formation of α-helices in fibrous proteins at the time, which he proposed to consist of alpha helices composed of heptad repeats, or seven-residue repeats (a-b-c-d-e-f-g), whereby 2 or more alpha helices twist around each other similar to the strands of a rope.

5. Borden American Cheese Singles. The truth is, so many of these cheeses taste identical. Borden and Harris Teeter are really similar, both lacking any distinct flavors that make them unique or ...
Here's what kale is, why it's so good for you and why some people should still avoid overconsumption.
Starch (a polymer of glucose) is used as a storage polysaccharide in plants, being found in the form of both amylose and the branched amylopectin. In animals, the structurally similar glucose polymer is the more densely branched glycogen, sometimes called "animal starch". Glycogen's properties allow it to be metabolized more quickly, which ...
Marking an end to more than 15 months of deadly conflict, Israel and Hamas reached a ceasefire deal on Wednesday that includes the release of captives held by both parties. The agreement was ...
