Csak az a furcsa, hogy a biokémiában csak ezt az egy vegyületcsoportot (3 db vegyületet)
nevezik "body"-knak ... |
|

.... "In physics, a physical body or physical object (or simply a body or object) is an identifiable collection of matter, which may be constrained by an identifiable boundary, and may move as a unit by translation or rotation, in 3-dimensional space."
https://en.wikipedia.org/wiki/Physical_body
És ez persze (hasonlóan) értelmezhető a (bio)kémiában is, szvsz.

a gúgli (vissza)fordítója pl.:
"antitest" --> "antibody"
|
|
| Walaki |
|
Szerintem itt is csak annyit jelent mint pl. a magyarban a 'test'.
pl. "antitest" ....
Rész, részecske értelemben, szvsz.

Miért hívják "ketone body"-nak az acetont és társait ?
A könyv csak annyit ír, hogy ennek történeti oka van, de nem írja le, hogy mi ez az ok ! |

Komplett kis gyártósorok  :
"Central to the process are the swinging lipoyllysyl arms of E2, which pass the two
electrons and the acetyl group derived from pyruvate from E1 to E3. All these enzymes and
coenzymes are clustered, allowing the intermediates to react quickly without ever diffusing
away from the surface of the enzyme complex."

"These two steps occur at separate active sites; the long flexible arm of biocytin permits
the transfer of activated carboxyl groups from the first active site to the second, much as
the long lipoyllysyl arm of E2 functions in the pyruvate dehydrogenase complex.

Szószedet: concert (együttműködés)
Some proteins endow cells and organisms with the ability to contract, to change shape,
or to move about. Actin and myosin function in the contractile system of skeletal muscle
and also in many nonmuscle cells. Tubulin is the protein from which microtubules are
built. Microtubules act in concert with the protein dynein in flagella and cilia (Fig. 6–1d)
to propel cells.

A hormone (from the Greek participle “ὁρμῶ”, "to set in motion, urge on") is any member of
a class of signaling molecules produced by glands in multicellular organisms that are
transported by the circulatory system to target distant organs to regulate physiology and
behaviour.

Szószedet: language of biochemistry (bioinformatika)
We begin in each case by considering the covalent structure of the simple subunits (amino
acids, fatty acids, monosaccharides, and nucleotides). These subunits are a major part of
the language of biochemistry; familiarity with them is a prerequisite for understanding more
advanced topics covered in this book, as well as the rapidly growing and exciting literature
of biochemistry.

Szószedet: simplicity (egyszerűség)
The relevant facts of biochemistry are many; the student approaching this subject for the
first time may occasionally feel overwhelmed. Perhaps the most encouraging development
in twentieth-century biology is the realization that, for all of the enormous diversity in
the biological world, there is a fundamental unity and simplicity to life. The organizing
principles, the biochemical unity, and the evolutionary perspective of diversity, provided
at the molecular level, will serve as helpful frames of reference for the study of
biochemistry.

Although living organisms contain a very large number of different proteins and different
nucleic acids, a fundamental simplicity underlies their structure (Chapter 1). The simple
monomeric subunits from which all proteins and all nucleic acids are constructed are few
in number and identical in all living species. Proteins and nucleic acids are informational
macromolecules: each protein and each nucleic acid has a characteristic information-rich
subunit sequence (Fig. 3–15).
Polysaccharides built from only a single kind of unit, or from two different alternating
units, are not informational molecules in the same sense as are proteins and nucleic acids
(Fig. 3–15). However, complex polysaccharides made up of six or more different kinds of
sugars connected in branched chains do have the structural and stereochemical variety
that enables them to carry information recognizable by other macromolecules.
