Book The Hidden Life of Trees

In March 23 2017, I borrowed in my local library an audio-book published in 2015 and titled: 

The Hidden Life of Trees: What They Feel, How They Communicate – Discoveries from a Secret World (English)

Das geheime Leben der Bäume:Was sie fühlen, wie sie kommunizieren - die Entdeckung einer verborgenen Welt (German original)

I wish most people had the information in it. I am deeply thankful to the author, Peter Wohlleben, and the researchers for their work. This was my tiny review of it at that time.

Some chapters touched me even deeper than others, and the last one brought me to tears. It was an invaluable read for me as a fruitarian and a human being.

Trees are living organisms - a tree that was recently cut in my area

My friend saved a tree, which someone had thrown out almost without roots, by planting it in his garden, and sent me another email update with "Poor tree" in the subject.

An admin  note to the members of the FruitDate group on Facebook:
Guys, this group exists as a tool for you to find each other, as an extension to and - please message each other privately if you see a friendly face, check their profiles, message them, and possibly develop friendships and intimate relationships.
Posts are now possible again but not necessary. Introducing yourself could be a nice idea, no one outside the group should know.
Please do not use this place for promotion. And remember that hardly anything shared through the internet could be considered truly private.

This is a good book for a fruitarian artist like me: about plants, beauty, and passion. The main topics are apples, tulips, marijuana, potato. Yo can learn - surprisingly - about specifics of opium high or flying penises (bees). Additionally, the author offers some interesting observations about life of plants and his position on GMO as a gardener.

Since September 2016, I watched quite a few videos on a YouTube channel à-bas-le-ciel by Eisel Mazard. I started with his critique on Durianrider and Freelee the Banana Girl, but then switched somehow to his older videos on veganism, and liked many of them. Even though I disagree with many of his views and his style of argumentation, I find it is good to have a channel like this in the vegan online world.

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. Apple
