What defines a food as being processed? A food is considered processed when it has been altered from its natural state for safety or convenience. The NOVA classification system defines processing levels from unprocessed or minimally processed (like cleaned and packaged fruits) to ultra-processed (li...
What Defines a Cell? Figure 1: Transport proteins in the cell membrane A plasma membrane is permeable to specific molecules that a cell needs. Transport proteins in the cell membrane allow for selective passage of specific molecules from the external environment. Each transport protein is specific ...
To create soy protein, manufacturers strip away the hulls and most of the fat from soybeans. The remaining portion of the soybean can then be ground down and turned into soy protein isolate. Soy foods are cholesterol-free and low in saturated fat, which defines soy as a healthy protein tha...
There seems to be a tendency to regard necrotic cell death as boring ± the inevitable consequence of energetic failure. However, there still must be a point of no return, and many intriguing questions remain. What defines the degree of energetic failure that can be tolerated and that which ...
In mammals, telomeres are composed of TTAGGG repeats, which are bound by a protein complex termed shelterin. Cell divisions lead to the progressive erosion of telomeric repeats. When telomeres become too short to recruit the shelterin complex, they become dysfunctional, leading to telomere ...
Technology companies are investing more in moonshots that address some of the world's greatest problems.Alphabet, parent company of Google, defines a moonshot as a project or proposal that does the following: addresses a huge problem that affects millions or billions of people; ...
There is an extremely long and very precise DNA molecule that defines all of the enzymes the cell needs. There are RNA polymerase enzymes attaching to the DNA strand at the starting points of different genes and copying the DNA for the gene into an mRNA molecule. The mRNA molecule floats ov...
Beans are high in protein, fiber, vitamins, and minerals, making them an excellent part of a healthy diet. 7 What defines a legume? A legume can refer to the plant, the pod, or the seeds of the Fabaceae family, known for their nitrogen-fixing ability and nutritional seeds. 6 Are peanu...
What defines a peptide? A peptide is defined as a short chain of amino acids linked by peptide bonds, generally not exceeding 50 units. 11 Do peptides have catalytic functions? Peptides generally do not have catalytic functions; their roles are mainly structural and signaling. 10 Are all enzy...
