All about fruitarianism with a long-term fruitarian, Lena

Running for Pleasure

Running and walking medium and long distance for pleasure as a fruitarian.

  • Last Runs and Walks in 2017

    Yes, today on my 17K walk I have seen this scene: two guys in red shirts were caring a white sofa through the park, and a boy in white ran around them.

    Below is a simple list of my more significant runs and walks (those much longer than 10K) in the last months of 2017, in kilometers (km, or K), starting with the most recent ones:

    • December: 17, 9, 9, 12, 9, 9, 8, 9, 7, 8, 10, 9, 7, 10
    • November: 10, 11, 8, 8, 7, 7, 7, 10, 10,11.

    I do not count those under 5K.

    It looks like I was not making my usual former 10K! I did not track the distance during the runs - it interrupts my audio-books, and I prefer to look at it later - and assumed that the distance I measured earlier was enough. Now I need to run about 1 km further to add 2K and make sure I make over 10 km (6.2 miles). There are a few days left in December, so maybe I could add a few 10s in my list.

  • 8K Walk / Run - Easing into the Morning Running

    After a too short night sleep :)

  • 8K Run + Unusual Vegan Fruitarian Salads

  • 18K Walk-Run to Newport Beach, Huntington Beach Restaurant, Berries for Lunch

  • 84K in December (10K Run)

  • 10K Walk / Run + Jump + Exercise - You Need Only Shoes

    Two-hour exercise outside on Saturday in SoCal (California).

  • 10K Walk / Run - Nature, Teens, Grand Battement, Vlogging, Personal Marketing, Lake

    Another walk and run along a destructed river and by a lake in Southern California: walking, jumping, running, accelerating, elements of ballet training, stretching, grand battement ([batmɑ̃], a movement in which both legs are kept straight and one leg is kicked outward from the body and in again). A few thoughts on freedom of mind, personal marketing on youtube, critique on building communities of loyal followers as a marketing strategy, "begging" for money and attention, cost of making videos.

  • 8K Run / Walk - Internet, Jumps, Empathy, Being in the Moment Limits

    Some thoughts during my morning walk / run: social networks and click-popularity, paying for reaching subscribers on facebook, escaping reality, fruits are not ideal food (there is no ideal food), plants matter regardless whether we can relate to them, alcohol and fast food, limited resources, we need to find ways to live together on this planet.

  • 10K Run - Eating Seeds or Fruit Only

    Another run; trees; talking about how eating juicy fruit only or adding seeds make me feel on the next days; confirmational bias, health related activities of a day: asanas and a few other exercises in the morning, then shower, and eating in the evening in two-three loads, consuming 1500 food calories; short fastings; energy for brain.

  • 13K Walk / Run To the Ocean and Back

    My tiny running story. Construction on the river. On the way back I packed my phone away, ran, and pain almost went away after a kilometer or two.

Albert Schweitzer

A man is ethical only when life, as such, is sacred to him, that of plants and animals as that of his fellow men, and when he devotes himself helpfully to all life that is in need of help. 

Protein Structure, Cooked and Denatured Proteins

Proteins are chains of amino acids. The sequence of amino acids in a chain is known as the primary structure of a protein. The chains fold up to form complex three dimensional shapes. The chains can fold on themselves locally (secondary structure) and wrap around themselves to form a specific three dimensional shape (tertiary structure).

The secondary / tertiary structure of a folded protein is directly related to its function. For example, enzymes are proteins that catalyze reactions. They have binding sites that interact with other molecules. These binding sites are created through the folding of the amino acid chains that gives rise to the three dimensional shape of the enzyme.

Denatured Protein

Denaturation of proteins involves the disruption and possible destruction of both the secondary and tertiary structures. Since denaturation reactions are not strong enough to break the peptide bonds, the primary structure (sequence of amino acids) remains the same after a denaturation process. Denaturation disrupts the normal sheets in a protein and uncoils it into a random shape.

Denaturation occurs because the bonding interactions responsible for the secondary structure (hydrogen bonds to amides) and tertiary structure are disrupted. In tertiary structure there are four types of bonding interactions between "side chains" including: hydrogen bonding, salt bridges, disulfide bonds, and non-polar hydrophobic interactions. which may be disrupted. 

Proteins can be denatured through exposure to heat or chemicals. Denatured proteins lose their three dimensional structure and thus their function. 

Digestion of Proteins and Cooking

Protein digestion begins in the stomach, where the acidic environment favors protein denaturation. Denatured proteins are more accessible as substrates for proteolysis than are native proteins. The primary proteolytic enzyme of the stomach is pepsin, a nonspecific protease that is maximally active at pH 2. Thus, pepsin can be active in the highly acidic environment of the stomach, even though other proteins undergo denaturation there.

Heat disrupts hydrogen bonds and non-polar hydrophobic interactions. This occurs because heat increases the kinetic energy and causes the molecules to vibrate so rapidly and violently that the bonds are disrupted

Foods are cooked to denature the proteins to make it easier for enzymes to digest them. Cooking food denatures some of the proteins in it and makes digestion more efficient. Heating to denature proteins in bacteria and thus destroy the bacteria.
