  2. Method of complements - Wikipedia

    en.wikipedia.org/wiki/Method_of_complements

    In the decimal numbering system, the radix complement is called the ten's complement and the diminished radix complement the nines' complement. In binary, the radix complement is called the two's complement and the diminished radix complement the ones' complement. The naming of complements in other bases is similar.

  3. Total complement activity - Wikipedia

    One can interpret the CH50 value along with the individual's complement factor values to help determine the etiology. For example, if and individual has normal C3/C4 values but a decreased CH50, that can indicate a terminal complement pathway deficiency while if one has low C3 and CH50 values that can indicate an autoimmune condition such as ...

  4. C1 complex - Wikipedia

    en.wikipedia.org/wiki/C1_complex

    The C1 complex (complement component 1, C1) is a protein complex involved in the complement system. It is the first component of the classical complement pathway and is composed of the subcomponents C1q, C1r and C1s. [1] [2] [3]

  5. Complementarity (molecular biology) - Wikipedia

    en.wikipedia.org/wiki/Complementarity_(molecular...

    Purines are larger than pyrimidines. Both types of molecules complement each other and can only base pair with the opposing type of nucleobase. In nucleic acid, nucleobases are held together by hydrogen bonding, which only works efficiently between adenine and thymine and between guanine and cytosine. The base complement A = T shares two ...

  6. Component (thermodynamics) - Wikipedia

    en.wikipedia.org/wiki/Component_(thermodynamics)

    Calculating the number of components in a system is necessary when applying Gibbs' phase rule in determination of the number of degrees of freedom of a system. The number of components is equal to the number of distinct chemical species (constituents), minus the number of chemical reactions between them, minus the number of any constraints ...

  7. Immune adherence - Wikipedia

    en.wikipedia.org/wiki/Immune_adherence

    The phenomenon is now resolved as a complement-dependent binding reaction of erythrocytes to microorganisms where specific antibodies are engaged in the process. [3] The reaction process is as follows: any microorganisms are bound with their specific antibodies, if they are produced, which activate the classical pathway of the complement system.

  8. Molecular mechanics - Wikipedia

    A force field is used to minimize the bond stretching energy of this ethane molecule.. Molecular mechanics uses classical mechanics to model molecular systems. The Born–Oppenheimer approximation is assumed valid and the potential energy of all systems is calculated as a function of the nuclear coordinates using force fields.

  9. Complement system - Wikipedia

    en.wikipedia.org/wiki/Complement_system

    Scheme of the complement system. The complement system, also known as complement cascade, is a part of the humoral, innate immune system and enhances (complements) the ability of antibodies and phagocytic cells to clear microbes and damaged cells from an organism, promote inflammation, and attack the pathogen's cell membrane.
