Glycobiology involves the study of biological sugars (glycans) which the body uses to create receptors on the surface of each cell. Missing glycans affect not only every disease, but nearly every biological process going on in the body. This means that basic functions within the cell can be disrupted when miscommunication takes place. Five functions common to all cells include nutrient uptake, reproduction, growth, waste removal and reacting to external changes. All living things are made up of cells, which serve as the basic building blocks of life, and all cells have a purpose in a living organism. Apoptosis or programmed cell death is also a function of the cell on its journey from life to death.

Apoptosis

It seems funny to talk about death while discussing the things of life, but it is a normal and necessary aspect of all mortal life. Cells wear out and need to be replaced so the organism (animal or human being) can continue living. Apoptosis is the name given to the myriad biological processes that can result in the death of the cell. Almost all cells have a programmed death date. Cells can initiate self-destruction internally when the time comes or respond to signals externally. When old cells die, they leave room for a new generation of cells to be born; in this way, the health of the larger organism is maintained and enhanced. Missing or altered sugars can disrupt this process and wreak havoc on the life of the organism. When apoptosis does not happen properly, degenerative diseases like cancer develop.

Cellular Biology—Life and Death

The human body loses between 50 and 86.4 billion cells every day, and the body needs to replace them with new cells to maintain normal function. There are millions of biological processes going on within each cell in the body every day. Apoptosis is just one of them and sugars are involved in facilitating almost all of these activities. If the sugars are not in place structurally, communication fails and the process cannot be completed properly. The cell functions then break down in a multitude of ways. Truly, disease begins at the cell level and missing sugars are an important part of that equation.

    Kitchen cooking oils will not last forever. Depending upon the oil, it can go rancid in a matter of months or a few years. You don't want to cook with rancid oil because it smells like wet socks and the living components have lost their vitality. But the good news is, expired oil won't hurt you. There is no water in it, so no mold can grow to make it rotten and dangerous. It can still be used for creative applications. According to the United States Department of Agriculture Forest Service, “Vegetable oils have many good natural properties including good lubricity, good resistance to shear, a high flash point, and a high viscosity index.” These qualities make them quite versatile in a number of applications. You might consider keeping your old oil rather than throwing it out. Recycling expired oil could prove to be a valuable asset in emergency situations.

    Disposable face masks, such as those health officials encouraged (or in some cases, mandated) the public to wear during the COVID-19 pandemic, are made of synthetic fibers and may contain chemical compounds. Many people have questioned the wisdom of wearing masks made of synthetic fibers for long periods, asking whether inhaling the chemical compounds masks release could lead to health problems.

    Deaths from Alzheimer's more than doubled between 2000 and 2019. In 2023, nearly 7 million Americans have been diagnosed with the disease. Today, 1 in 3 seniors dies with Alzheimer's or dementia—the death toll exceeds the total of breast- and prostate cancer combined. Officially, it's the sixth-leading cause of death, but a 2014 study suggests that it is actually one of the top three (just behind heart disease and cancer). The discrepancy being how death certificates underreport the disese because they record the more immediate cause of death (pneumonia or heart attack) rather than listing the underlyings causes.

    True confessions: I never liked flossing, so I rarely used the string. Angie used all of the flossing strings I collected from the dentist to cut the dough when making cinnamon rolls—I thought that was a better and tastier use! I always brushed my teeth (manually and with a battery operated toothbrush). My teeth felt clean enough, but still, I had a lot of dental guilt every 6 months when I had to admit I wasn't flossing. A few years ago, I found a device that removed all my guilt and shame! I discovered the waterpik. A waterpik (also known as a dental water jet) is a brand of water flosser or oral irrigator that sprays water to remove food from between your teeth. Water flossers are a fabulous option for people who have trouble with traditional flossing—the kind that involves threading string-like material between your teeth. The girl in the picture looks like me trying to floss!
